Regenerative Drives
Most non-regenerative, variable speed, DC drives control current
flow to a motor in one direction. The direction of current flow is the
same direction as the motor rotation. Non-regenerative drives
operate in Quadrant 1, and also in Quadrant 3 if the drive is
reversible (see Figure 1, page VI). Motors must stop before
reversing direction. Unless dynamic braking is used, non-
regenerative drives cannot decelerate a load faster than coasting to
a lower speed.
Regenerative drives operate in two additional quadrants: Quadrant
2 and Quadrant 4. In these quadrants, motor torque is in the
opposite direction of motor rotation.
This allows regenerative drives to reverse a motor without
contactors or switches, to control an overhauling load, and to
decelerate a load faster than it would take to coast to a lower
speed.

Installation
Mounting
Warning
Do not install, rewire, or remove this control with input power applied. Doing so may cause fire or serious injury. Make sure you have read and understood the Safety Warnings on page i before attempting installation.
• Drive components are sensitive to electrostatic fields. Avoid
direct contact with the circuit board. Hold drive by the chassis
only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and
calibration trimpots.
• Mount the drive away from heat sources. Operate the drive
within the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of the
drive.
• 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 head
screws. Fasten either the large base or the narrow flange of the
chassis to the subplate.
• The chassis should be earth grounded. Use a star washer
beneath the head of at least one of the mounting screws to
penetrate the anodized chassis surface and to reach bare metal.
Wiring
Warning
Do 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. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements.
Do not disconnect any of the motor leads from the drive unless power is removed or the drive is disabled. Opening any one motor lead while the drive is running may destroy the drive.
• Use 18 AWG wire for speed adjust potentiometer wiring. Use 14
AWG wire for AC line (L1, L2) and motor (A1, A2) wiring.

Shielding guidelines
Warning
Under no circumstances should power and logic leads be bundled together. Induced voltage can cause unpredictable behavior 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, Minarik
recommends shielding all logic-level leads. If shielding of all logic-
level leads is not practical, the user should twist all logic leads with
themselves to minimize induced noise.
It may be necessary to earth ground the shielded cable. If noise is
produced by devices other than the drive, ground the shield at the
drive end. If noise is generated by a device on the drive, ground
the shield at the end away from the drive. Do not ground both ends
of the shield.
If the drive continues to pick up noise after grounding the shield, it
may be necessary to add AC line filtering devices, or to mount the
drive in a less noisy environment.
Logic wires from other input devices, such as motion controllers
and PLL velocity controllers, must be separated from power lines in
the same manner as the logic I/O on this drive.
Heat sinking
The RG60U drive requires an additional heat sink when the
continuous armature current is above 5 ADC. Use Minarik heat sink
kit part number 223-0159. Use a thermally conductive heat sink
compound (such as Dow Corning®340 Heat Sink compound)
between the drive chassis and the heat sink surface for optimum
heat transfer.
Line fusing
Minarik drives should be used with fuses for protection. Use fast
acting fuses rated for 250 VAC or higher. Fuse L1 only when the
line voltage is 115 VAC. Fuse both L1 and L2 when the line voltage
is 230 VAC.
Table 1 on page 8 lists the recommended line fuse sizes.

Speed adjust potentiometer
Warning
Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the drive.
Mount the speed adjust potentiometer through a 0.38 in. (10 mm)
hole with the hardware provided (Figure 4). Install the circular
insulating disk between the panel and the 10K ohm speed adjust
potentiometer.
Twist the speed adjust potentiometer wire to avoid picking up
unwanted electrical noise. If speed adjust potentiometer wires are
longer than 18 in. (46 cm), use shielded cable. Keep speed adjust
potentiometer wires separate from power leads (L1, L2, A1, A2).

Connections
Screw terminal block
Most connections to the RG60U drive are made to a screw terminal block (part number 160-0171). Using a screwdriver, turn the terminal block screw counterclockwise to open the wire clamp. Insert 18 AWG stripped wire into the wire clamp. Turn the terminal block screw clockwise to clamp the wire.
Cage-clamp terminal block
Inhibit and enable connections are made to a cage-clamp terminal block. To insert a wire into the terminal block, press down on the lever arm using a small screwdriver. Insert 20 AWG stripped wire into the wire clamp in front of the terminal block. Release the lever arm to clamp the wire.

Installation
Warning
Do not connect this equipment with power applied. Failure to heed this directive may result in fire or serious injury.
Minarik strongly recommends the installation of a master power switch in the voltage input line, as shown in Figure 7, page 13. The switch contacts should be rated at a minimum
of 200% of motor nameplate current and 250 volts.
Power, fuse and motor connections
Connect the power input leads, an external line fuse and a DC
motor to the drive’s printed circuit board (PCB) as shown in Figure
7, page 13.
Motor
Minarik drives supply motor voltage from A1 and A2 terminals. It is
assumed throughout this manual that, when A1 is positive with
respect to A2 , the motor will rotate clockwise (CW) while looking at
the output shaft protruding from the front of the motor. If this is
opposite of the desired rotation, simply reverse the wiring of A1 and
A2 with each other (A1 - and A2 +).
11
Connect a DC motor to PCB terminals A1 and A2 as shown in
Figure 7, page 13. Ensure that the motor voltage rating is
consistent with the drive’s output voltage.
12
Installation
Power input
Connect the AC line power leads to terminals L1 and L2, or to a
double-throw, single-pole master power switch (recommended).
Line fuse
Wire an external line fuse between the stop switch (if installed) and
the terminal board (Figure 7, page 13). An additional line fuse
should be installed on L2 if the input voltage is 230 VAC. Refer to
the line fuse table (Table 1 on page 8) for fuse ratings.

Speed adjust potentiometer connections
The motor can operate in one direction (unidirectional) or two
directions (bidirectional) depending on how the speed adjust
potentiometer 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 operate
when the wiper is in the center position. Turning the wiper
clockwise (CW) from the center position causes the motor to rotate
in 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 adjust
potentiometer connections.

Voltage or Current Follower (non-isolated signal, -PCM models)
PCM series drives can be configured to follow a grounded (non-
isolated) voltage or current signal. To configure the drive to follow
a voltage or current signal, connect the signal leads to the +IN and
-IN terminals on TB501, observing proper polarity. Ensure that the
following jumper terminals are properly set:
J501 Settings
Open pins 1 & 2 for -10 to +10 VDC signal or pot input.
Jumper pins 1 & 2 for 4 to 20 mA signal input.
J502 Settings
Jumper 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 input
polarity, connect the DIR terminal to the +5V terminal on TB501 of
the PCM board. A single-pole, single-throw switch can be used as
a polarity reversal switch. Close the switch to reverse the output
voltage polarity. Open the switch to return the output voltage back
to its original polarity. See Figure 12, page 20 for polarity reversal
switch connections.

Operation
Warning
Dangerous voltages exist on the drive when it is powered. BE ALERT. High voltages can cause serious or fatal injury. For your safety, use personal protective equipment (PPE) when operating this drive.
Before applying power:
1. Verify that no conductive material is present on the printed
circuit board.
2. Ensure that all switches and jumpers are properly set.
21
22
Operation
Startup and shutdown
To start the drive:
1. Set the speed adjust potentiometer or reference voltage to zero
speed.
2. Apply AC line voltage.
3. Slowly turn the speed adjust potentiometer clockwise or
counterclockwise to rotate the motor in the forward or reverse
direction. If in a voltage follower mode, slowly increase the
voltage in either the positive or negative direction to rotate the
motor in the forward or reverse direction. Continue until the
desired speed is reached.
4. To decelerate the motor from set speed to a stop, reset the
speed adjust potentiometer to zero speed, or reference voltage
to zero. To coast the motor from set speed to a stop, remove
AC line voltage from the drive .
If the motor or drive does not perform as described, disconnect the
AC line voltage immediately. Refer to the Troubleshooting section
for further assistance.
Starting and Stopping Methods
Warning
Decelerating to minimum speed, regenerative braking, or coasting to a stop is recommended for frequent starts and stops. Do not use any of these methods for emergency stopping. They may not stop a drive that is malfunctioning. Removing AC line power (both L1 and L2) is the only acceptable method for emergency stopping.
For this reason, Minarik strongly recommends installing an emergency stop switch on both the L1 and L2 inputs (see Figure 7, page 13).
Frequent decelerating to minimum speed or regenerative braking produces high torque. This may cause damage to motors, especially gearmotors that are not properly sized for the application
Automatic restart upon power restoration
All drives automatically run to set speed when power is applied and
enabled.
23
24
Operation
Decelerate to a stop
The RUN/STOP switch in Figure 13 may be used to decelerate a
motor to a stop. Closing the switch between RB1 and RB2
decelerates the motor from set speed to a stop. The FWD ACC and
REV ACC trimpot settings determine the rate at which the will drive
decelerate to a stop and accelerate back to set speed. Set the switch
to the RUN position to accelerate the motor to set speed.

Operation
Regenerative brake
To regeneratively brake the motor, short the INHIBIT terminals on
TB503. Reopening the INHIBIT terminals causes the motor to
accelerate to set speed (see Figure 14, page 27 for INHIBIT
terminal locations and Figure 15, page 28 for INHIBIT settings).
Twist inhibit wires and separate them from other power-carrying
wires or sources of electrical noise. Use shielded cable if the inhibit
wires are longer than 18 in. (46 cm). If shielded cable is used,
ground only one end of the shield to earth ground. Do not ground
both ends of the shield.
Coast to a stop
To coast the motor to a stop without removing power to the drive,
short the ENABLE terminals on TB503 (see Figure 14, page 27 for
ENABLE terminal locations and Figure 16, page 29 for ENABLE
settings).
Momentarily shorting the ENABLE terminals will coast the motor to
zero speed, then accelerate back to set speed.
25
Completely shorting the ENABLE terminals will coast the motor to a
complete stop. Reopening the ENABLE terminals causes the
motor to accelerate to set speed.
26
Operation
Invert Inhibit and Invert Enable
INVERT modes reverse the function of the INHIBIT and ENABLE
terminals. Each drive is assembled with the INVERT INHIBIT and
INVERT ENABLE jumper settings open (jumpers on location 1 and
4 of JP502). See Figure 14, page 27 for JP502 location.
To activate the INVERT INHIBIT mode, jumper locations 1 and 2 of
JP502 (see Figure 15, page 28). In INVERT INHIBIT mode, the
motor will regeneratively brake when inhibit terminals are open. To
accelerate 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 motor
will coast to a stop when the enable terminals are open. To
accelerate the motor to set speed, close the enable terminals.

Calibration
Warning
Dangerous voltages exist on the drive when it is powered. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots must be adjusted with power applied, use insulated tools and the appropriate personal protection equipment. BE ALERT. High voltages can cause serious or fatal injury.
The RG60U has nine user adjustable trimpots: FWD ACC, REV
ACC, MAX SPD, IR COMP, REV TQ, FWD TQ, DB, MIN SPD, and
TACH. Each drive is factory calibrated to its maximum current
rating. Readjust the calibration trimpot settings to accommodate
lower current rated motors.
All adjustments increase with clockwise rotation, (CW) and
decrease with counterclockwise (CCW) rotation. Use a non-metallic
screwdriver for calibration. Each trimpot is identified on the printed
circuit board. See Figure 17, page 31 for RG60U calibration
trimpot locations.

Calibration
MINIMUM SPEED (MIN SPD)
The MIN SPD trimpot setting determines the minimum speed when
the speed adjust potentiometer is turned full CCW. It is factory set
to zero speed. The minimum speed feature applies only when the
drive is operating in unidirectional mode.
To calibrate MIN SPD:
1. Set the speed adjust potentiometer to full CCW.
2. Adjust the MIN SPD trimpot until the desired minimum motor
speed is reached.
MAXIMUM SPEED (MAX SPD)
The MAX SPD trimpot setting determines the maximum
forward and reverse speed. It is factory set for maximum rated
motor speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Turn the speed adjust potentiometer CW so that the motor is
running at full speed.
3. Adjust the MAX SPD trimpot until the desired maximum motor
speed is reached.
Caution! Do not attempt to run motor above 90 VDC on 115 VAC
or above 180 VDC on 230 VAC.
Calibration
FORWARD TORQUE (FWD TQ)
Warning
Although FWD TQ can be set to 120% of motor nameplate current rating, continuous operation beyond this rating may damage the motor. If you intend to operate beyond this rating, contact your Minarik representative for assistance.
The FWD TQ setting determines the maximum current limit for accelerating and driving the motor in the forward direction. It is factory set at 120% of maximum rated drive current.
See Figure 19 (page 39) for typical FWD TQ calibration settings or
use the following procedure to recalibrate FWD TQ:
1. With the power disconnected from the drive, connect a DC ammeter in series with the armature.
2. Set the FWD TQ trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum (full CW).
4. Carefully lock the motor armature. Be sure that the motor is firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the FWD TQ trimpot CW slowly until the armature current is 120% of motor rated armature current.
7. Set the speed adjust potentiometer to minimum.
8. Remove the power from the drive.
9. Unlock the motor shaft.
10. Remove the ammeter in series with the motor armature if it is
no longer needed and re-apply power to the drive.
33
34
Calibration
REVERSE TORQUE (REV TQ)
Warning
Although REV TQ can be set to 120% of motor nameplate curren rating, continuous operation beyond this rating may damage the motor. If you intend to operate beyond this rating, contact your Minarik representative for assistance.
The REV TQ setting determines the maximum current limit for accelerating and driving the motor in the reverse direction. It is factory set at 120% of maximum rated drive current.
See Figure 19 (page 39) for typical REV TQ calibration settings or
use the following procedure to recalibrate REV TQ:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the REV TQ trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum (full CW).
4. Carefully lock the motor armature. Be sure that the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the REV TQ trimpot CW slowly until the armature
current is 120% of motor rated armature current.
7. Set the speed adjust potentiometer to minimum.
8. Remove the power from the drive.
9. Unlock the motor shaft.
10. Remove the ammeter in series with the motor armature if it is
no longer needed and re-apply power to the drive.
Calibration
IR COMPENSATION (IR COMP)
The IR COMP trimpot setting determines the degree to which
motor speed is held constant as the motor load changes. It is
factory set for optimum motor regulation.
See Figure 19 (page 39) for typical IR COMP calibration settings or
use the following procedure to recalibrate the IR COMP setting:
1. Set the IR COMP trimpot to minimum (full CCW).
2. Rotate the speed adjust potentiometer until the motor runs at
mid-speed without load (for example, 900 RPM for an 1800
RPM motor). A hand held tachometer may be used to measure
motor speed.
3. Load the motor armature to its full load armature current rating.
The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP
trimpot until the motor runs at the speed measured in step 2. If
the motor oscillates (overcompensation), the IR COMP trimpot
may be set too high (CW). Turn the IR COMP trimpot CCW to
stabilize the motor.
5. Unload the motor.
35
36
Calibration
FORWARD ACCELERATION (FWD ACC)
The FWD ACC setting determines the time the motor takes to ramp
to either a higher speed in the forward direction or a lower speed in
the reverse direction, within the limits of available torque. The
FWD ACC setting is factory set for its fastest forward acceleration
time.
Turn the FWD ACC trimpot CW to increase the forward
acceleration time, and CCW to decrease the forward acceleration
time.
REVERSE ACCELERATION (REV ACC)
The REV ACC setting determines the time the motor takes to ramp
to either a higher speed in the reverse direction or a lower speed in
the forward direction, within the limits of available torque. The REV
ACC setting is factory set for its fastest reverse acceleration time.
Turn the REV ACC trimpot CW to increase the reverse acceleration
time, and CCW to decrease the reverse acceleration time.
App

s
Calibration
DEADBAND (DB)
The deadband trimmer potentiometer determines the time that will
elapse between the application of current in one direction before
current is applied in the opposite direction.
The deadband trimmer potentiometer affects the resistance that a
motor has to changes in shaft position at zero speed. It does this
by applying AC voltage to the motor armature.
Deadband is factory calibrated with the notch at approximately the
3 o’clock position for 60 Hz AC line operation. Recalibrate the
deadband with the notch at the 9 o’clock position for 50 Hz AC line
operation. If you hear motor noise (humming), the deadband might
be set too high. Turn the deadband trimpot CCW until the motor
noise ceases.

Calibration
TACH GENERATOR (TACH)
Calibrate the TACH setting only when a tachogenerator is used.
The TACH setting, like the IR COMP setting, determines the
degree to which motor speed is held constant as the motor load
changes.
To calibrate the TACH trimpot:
1. Connect the tachogenerator to T1 and T2. The polarity is
positive (+) for T1 and negative (-) for T2 with the motor running
in forward direction.
2. Set SW503 to ARM for armature feedback.
3. Set the speed adjust potentiometer full CW. Measure the
armature voltage across A1 and A2 using a voltmeter.
4. Set the speed adjust potentiometer to 0 (zero speed).
5. Set SW503 to TACH for tachogenerator feedback.
6. Set the IR COMP trimpot to full CCW.
7. Set the TACH trimpot to full CW.
8. Apply line power.
9. Set the speed adjust potentiometer to full CW.
10. Adjust the TACH trimpot until the armature voltage is the same
value as the voltage measured in step 3.
Check that the tachogenerator is properly calibrated. The motor
should run at the same speed when SW503 is set to either
armature or tachogenerator feedback.

Warning
This trimpot is set at the factory and should not need adjustment. Do not adjust this trimpot unless you are experiencing drift problems. Contact your Minarik representative before attempting adjustment.
The RG60U-PCM has a factory-set offset to guarantee stability in a stopped motor. To calibrate the OFFSET trimpot:
1. Ensure that the input power is turned OFF.
2. Set the input signal to zero.
3. Set the OFFSET trimpot to the approximate midrange or 50%.
Note: This is a 25-turn potentiometer. After setting the trimpot to zero full CCW, make 5 full rotations to reach midrange, or 50%.
4. Apply power and observe the motor.
5. If the motor shaft drifts, or slowly rotates with no signal applied, adjust the OFFSET trimpot until the motor shaft stops. The direction and amount of trimpot adjustment depends on the direction of the shaft rotation and connection of the motor leads.
See Figure 20 on page 40 for OFFSET trimpot location.

Troubleshooting
Warning
Dangerous voltages exist on the drive when it is powered. When possible, disconnect the drive while troubleshooting. High voltages can cause serious or fatal injury.
Before applying power
Check the following steps before proceeding:
1. The AC line voltage must be connected to the proper terminals.
2. Check that the voltage switches and jumpers are set correctly.
3. The motor must be rated for the drive’s rated armature voltage
and current.
4. Check that all terminal block connections are correct.
For additional assistance, contact your local Minarik distributor, or
the factory direct:
1-800-MINARIK (646-2745) or Fax: 1-800-394-6334
49Troubleshooting
Problem Possible
Causes
Line fuse blows. 1. Line fuse is the
wrong size.
2. Motor cable or armature is shorted to ground.
3. Nuisance tripping caused by a combination of ambient conditions and high-current spikes (i.e. reversing).
Suggested Solutions
1. Check that the line fuse is correct for the motor size.
2. Check motor cable and armature for shorts.
3. Add a blower to cool the drive components; decrease FWD TQ and REV TQ settings, or resize motor and drive for actual load demand, or check for incorrectly aligned mechanical components or “jams”.
50
Troubleshooting
Problem Possible
Causes
Line fuse does not blow, but the motor does not run.
1. Speed adjust potentiometer or speed reference voltage is set to zero speed.
2. Speed adjust potentiometer or speed reference voltage is not connected to drive input properly; connections are open.
3. INHIBIT terminals are shorted.
4. S2 is shorted to S0.
5. Drive is in current limit.
6. Drive is not receiving AC line voltage.
7. Motor is not
connected.
Suggested Solutions
1. Increase the speed adjust potentiometer setting or speed reference voltage.
2. Check connections to input. Verify that connections are not open.
3. Remove the short from the INHIBIT terminals.
4. Remove short.
5. Verify that motor is not jammed. Increase FWD TQ or REV TQ setting if they are set too low.
6. Apply AC line voltage to L1 and L2.
7. Connect motor to A1 and A2.
Troubleshooting
51
Problem Possible
Causes
Motor runs too fast.
Motor will not reach the desired speed.
Motor pulsates or surges under load.
MAX SPD not calibrated.
1. MAX SPD setting is too low.
2. IR COMP setting is too low.
3. Motor is overloaded.
4. Drive is in current limit.
1. IR COMP is set too high.
2. Motor bouncing in and out of current limit.
Suggested Solutions
Calibrate MAX SPD.
1. Increase MAX SPD setting.
2. Increase IR COMP setting.
3. Check motor load. Resize the motor if necessary.
4. Verify torque
settings.
1. Adjust the IR COMP setting slightly CCW until the motor speed stabilizes.
2. Make sure motor is not undersized for load; adjust FWD TQ and REV TQ trimpot CW.
