vRegenerative DrivesMost non-regenerative, variable speed, DC drives control currentflow to a motor in one direction. The direction of current flow is thesame direction as the motor rotation. Non-regenerative drivesoperate in Quadrant 1, and also in Quadrant 3 if the drive isreversible (see Figure 1, page VI). Motors must stop beforereversing direction. Unless dynamic braking is used, nonregenerative drives cannot decelerate a load faster than coasting toa lower speed.Regenerative drives operate in two additional quadrants: Quadrant2 and Quadrant 4. In these quadrants, motor torque is in theopposite direction of motor rotation.This allows regenerative drives to reverse a motor withoutcontactors or switches, to control an overhauling load, and todecelerate a load faster than it would take to coast to a lowerspeed.

4InstallationMounting WarningDo not install, rewire, or remove this control with input powerapplied. Doing so may cause fire or serious injury. Make sureyou have read and understood the Safety Warnings on page ibefore attempting installation. Drive components are sensitive to electrostatic fields. Avoiddirect contact with the circuit board. Hold drive by the chassisonly. Protect the drive from dirt, moisture, and accidental contact. Provide sufficient room for access to the terminal block andcalibration trimpots. Mount the drive away from heat sources. Operate the drivewithin the specified ambient operating temperature range. Prevent loose connections by avoiding excessive vibration of thedrive. Mount drive with its board in either a horizontal or vertical plane.Six 0.19 in. (5 mm) wide slots in the chassis accept #8 pan headscrews. Fasten either the large base or the narrow flange of thechassis to the subplate. The chassis should be earth grounded. Use a star washerbeneath the head of at least one of the mounting screws topenetrate the anodized chassis surface and to reach bare metal.
Installation5Wiring WarningDo not install, rewire, or remove this control with input power applied. Failure to heed this warning may result in fire,explosion, or serious injury.Circuit potentials are at 115 or 230 VAC above ground. Toprevent the risk of injury or fatality, avoid direct contact with theprinted circuit board or with circuit elements.Do not disconnect any of the motor leads from the drive unlesspower is removed or the drive is disabled. Opening any onemotor lead while the drive is running may destroy the drive. Use 18 AWG wire for speed adjust potentiometer wiring. Use 14AWG wire for AC line (L1, L2) and motor (A1, A2) wiring.
6InstallationShielding guidelines WarningUnder no circumstances should power and logic leads bebundled together. Induced voltage can cause unpredictablebehavior in any electronic device, including motor controls.As a general rule, Minarik recommends shielding of all conductors.If it is not practical to shield power conductors, Minarikrecommends shielding all logic-level leads. If shielding of all logiclevel leads is not practical, the user should twist all logic leads withthemselves to minimize induced noise.It may be necessary to earth ground the shielded cable. If noise isproduced by devices other than the drive, ground the shield at thedrive end. If noise is generated by a device on the drive, groundthe shield at the end away from the drive. Do not ground both endsof the shield.If the drive continues to pick up noise after grounding the shield, itmay be necessary to add AC line filtering devices, or to mount thedrive in a less noisy environment.Logic wires from other input devices, such as motion controllersand PLL velocity controllers, must be separated from power lines inthe same manner as the logic I/O on this drive.
Installation7Heat sinkingThe RG60U drive requires an additional heat sink when thecontinuous armature current is above 5 ADC. Use Minarik heat sinkkit part number 223-0159. Use a thermally conductive heat sinkcompound (such as Dow Corning 340 Heat Sink compound)between the drive chassis and the heat sink surface for optimumheat transfer.Line fusingMinarik drives should be used with fuses for protection. Use fastacting fuses rated for 250 VAC or higher. Fuse L1 only when theline voltage is 115 VAC. Fuse both L1 and L2 when the line voltageis 230 VAC.Table 1 on page 8 lists the recommended line fuse sizes.

InstallationSpeed adjust potentiometer WarningBe sure that the potentiometer tabs do not make contact withthe potentiometer enclosure. Grounding the input will causedamage to the drive.Mount the speed adjust potentiometer through a 0.38 in. (10 mm)hole with the hardware provided (Figure 4). Install the circularinsulating disk between the panel and the 10K ohm speed adjustpotentiometer.Twist the speed adjust potentiometer wire to avoid picking upunwanted electrical noise. If speed adjust potentiometer wires arelonger than 18 in. (46 cm), use shielded cable. Keep speed adjustpotentiometer wires separate from power leads (L1, L2, A1, A2).MOUNT THROUGH A 0.38 IN.

Installation11 WarningDo not connect this equipment with power applied. Failureto heed this directive may result in fire or serious injury.Minarik strongly recommends the installation of a masterpower switch in the voltage input line, as shown in Figure7, page 13. The switch contacts should be rated at a minimumof 200% of motor nameplate current and 250 volts.Power, fuse and motor connectionsConnect the power input leads, an external line fuse and a DCmotor to the drive’s printed circuit board (PCB) as shown in Figure7, page 13.MotorMinarik drives supply motor voltage from A1 and A2 terminals. It isassumed throughout this manual that, when A1 is positive withrespect to A2 , the motor will rotate clockwise (CW) while looking atthe output shaft protruding from the front of the motor. If this isopposite of the desired rotation, simply reverse the wiring of A1 andA2 with each other (A1 - and A2 ).Connect a DC motor to PCB terminals A1 and A2 as shown inFigure 7, page 13. Ensure that the motor voltage rating isconsistent with the drive’s output voltage.
12InstallationPower inputConnect the AC line power leads to terminals L1 and L2, or to adouble-throw, single-pole master power switch (recommended).Line fuseWire an external line fuse between the stop switch (if installed) andthe terminal board (Figure 7, page 13). An additional line fuseshould be installed on L2 if the input voltage is 230 VAC. Refer tothe line fuse table (Table 1 on page 8) for fuse ratings.

14InstallationSpeed adjust potentiometer connectionsThe motor can operate in one direction (unidirectional) or twodirections (bidirectional) depending on how the speed adjustpotentiometer is connected to the drive.Connect the speed adjust potentiometer as shown in Figure 8(a),page 15 for bidirectional operation. The motor does not operatewhen the wiper is in the center position. Turning the wiperclockwise (CW) from the center position causes the motor to rotatein one direction, while turning the wiper counterclockwise (CCW)causes rotation in the opposite direction.Connect the speed adjust potentiometer as shown in Figure 8(b),page 15 for unidirectional operation in the forward direction.Connect the speed adjust potentiometer as shown in Figure 8(c),page 15 for unidirectional operation in the reverse direction.Refer to the Application Notes section for additional speed adjustpotentiometer connections.

Installation19Voltage or Current Follower (non-isolatedsignal, -PCM models)PCM series drives can be configured to follow a grounded (nonisolated) voltage or current signal. To configure the drive to followa voltage or current signal, connect the signal leads to the IN and-IN terminals on TB501, observing proper polarity. Ensure that thefollowing jumper terminals are properly set:J501 SettingsOpen pins 1 & 2 for -10 to 10 VDC signal or pot input.Jumper pins 1 & 2 for 4 to 20 mA signal input.J502 SettingsJumper pins 2 & 3 for -10 to 10 VDC signal or pot input.Jumper pins 1 & 2 for 4 to 20 mA signal input.See Figure 12, page 20 for jumper and terminal locations.Polarity reversal switch (-PCM models)To reverse the output voltage polarity without changing the inputpolarity, connect the DIR terminal to the 5V terminal on TB501 ofthe PCM board. A single-pole, single-throw switch can be used asa polarity reversal switch. Close the switch to reverse the outputvoltage polarity. Open the switch to return the output voltage backto its original polarity. See Figure 12, page 20 for polarity reversalswitch connections.

21Operation WarningDangerous voltages exist on the drive when it is powered. BEALERT. High voltages can cause serious or fatal injury. Foryour safety, use personal protective equipment (PPE) whenoperating this drive.Before applying power:1. Verify that no conductive material is present on the printedcircuit board.2. Ensure that all switches and jumpers are properly set.
22OperationStartup and shutdownTo start the drive:1. Set the speed adjust potentiometer or reference voltage to zerospeed.2. Apply AC line voltage.3. Slowly turn the speed adjust potentiometer clockwise orcounterclockwise to rotate the motor in the forward or reversedirection. If in a voltage follower mode, slowly increase thevoltage in either the positive or negative direction to rotate themotor in the forward or reverse direction. Continue until thedesired speed is reached.4. To decelerate the motor from set speed to a stop, reset thespeed adjust potentiometer to zero speed, or reference voltageto zero. To coast the motor from set speed to a stop, removeAC line voltage from the drive .If the motor or drive does not perform as described, disconnect theAC line voltage immediately. Refer to the Troubleshooting sectionfor further assistance.
23Starting and Stopping Methods WarningDecelerating to minimum speed, regenerative braking, orcoasting to a stop is recommended for frequent starts andstops. Do not use any of these methods for emergencystopping. They may not stop a drive that is malfunctioning.Removing AC line power (both L1 and L2) is the onlyacceptable method for emergency stopping.For this reason, Minarik strongly recommends installing anemergency stop switch on both the L1 and L2 inputs (seeFigure 7, page 13).Frequent decelerating to minimum speed or regenerativebraking produces high torque. This may cause damage tomotors, especially gearmotors that are not properly sized forthe applicationAutomatic restart upon power restorationAll drives automatically run to set speed when power is applied andenabled.
24OperationDecelerate to a stopThe RUN/STOP switch in Figure 13 may be used to decelerate amotor to a stop. Closing the switch between RB1 and RB2decelerates the motor from set speed to a stop. The FWD ACC andREV ACC trimpot settings determine the rate at which the will drivedecelerate to a stop and accelerate back to set speed.

Operation25Regenerative brakeTo regeneratively brake the motor, short the INHIBIT terminals onTB503. Reopening the INHIBIT terminals causes the motor toaccelerate to set speed (see Figure 14, page 27 for INHIBITterminal locations and Figure 15, page 28 for INHIBIT settings).Twist inhibit wires and separate them from other power-carryingwires or sources of electrical noise. Use shielded cable if the inhibitwires are longer than 18 in. (46 cm). If shielded cable is used,ground only one end of the shield to earth ground. Do not groundboth ends of the shield.Coast to a stopTo coast the motor to a stop without removing power to the drive,short the ENABLE terminals on TB503 (see Figure 14, page 27 forENABLE terminal locations and Figure 16, page 29 for ENABLEsettings).Momentarily shorting the ENABLE terminals will coast the motor tozero speed, then accelerate back to set speed.Completely shorting the ENABLE terminals will coast the motor to acomplete stop. Reopening the ENABLE terminals causes themotor to accelerate to set speed.
26OperationInvert Inhibit and Invert EnableINVERT modes reverse the function of the INHIBIT and ENABLEterminals. Each drive is assembled with the INVERT INHIBIT andINVERT ENABLE jumper settings open (jumpers on location 1 and4 of JP502). See Figure 14, page 27 for JP502 location.To activate the INVERT INHIBIT mode, jumper locations 1 and 2 ofJP502 (see Figure 15, page 28). In INVERT INHIBIT mode, themotor will regeneratively brake when inhibit terminals are open. Toaccelerate the motor to set speed, close the inhibit terminals.To activate the INVERT ENABLE mode, jumper locations 3 and 4,(see Figure 16, page 29). In INVERT ENABLE mode, the motorwill coast to a stop when the enable terminals are open. Toaccelerate the motor to set speed, close the enable terminals.

However, PCM cells can endure only a maximum of 107-108 writes, making a PCM based memory sys-tem have a lifetime of only a few years under ideal conditions. Fur-thermore, we show that non-uniformity in writes to different cells reduces the achievable lifetime of PCM system by 20x. Writes to PCM cells
