Please read these instructions carefully before performing
any of the procedures contained in this manual.
•
DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT
WITH POWER APPLIED. Have a qualified electrical technician
install, adjust and service this equipment. Follow the National
Electrical Code and all other applicable electrical and safety
codes, including the provisions of the Occupational Safety and
Health Act (OSHA), when installing equipment.
•
Reduce the chance of an electrical fire, shock, or explosion by
proper grounding, over-current protection, thermal protection,
and enclosure. Follow sound maintenance procedures.
It is possible for a drive to run at full speed as a result
of a component failure. Minarik strongly recommends the
installation of a master switch in the main power input to
stop the drive in an emergency.
Circuit potentials are at 115 VAC or 230 VAC above earth
ground. Avoid direct contact with the printed circuit board or
with circuit elements to prevent the risk of serious injury or
fatality. Use a non-metallic screwdriver for adjusting the
calibration trimpots. Use approved personal protective
equipment and insulated tools if working on this drive with
power applied.

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 Quadrant 3 if the drive is reversible (see
Figure 1, page viii). 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.
Regenerative drives can reverse a motor without contactors,
switches, brake resistors and inhibit plugs. They can also control
an overhauling load and decelerate a load faster than it would take
to coast to a lower speed.

the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of
the drive.
Drive mounting (MMRGD)
• Mount the drive with its board in either a horizontal or vertical
plane. Eight (8) 0.188 inch [4.8 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 drive must be earth grounded for noise suppression.
Connect earth ground to the earth ground terminal on the drive’s
bottom board (see Figure 10, page 19, for location).

Wiring
Warning
Do not install, remove, or rewire this equipment with 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 may destroy the drive.
• Use 18 AWG wire for speed adjust potentiometer wiring. Use 16
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 logic
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
MMRGD10 series drives require heat sink kit 223-0159 when the
continuous armature current is above 5 ADC. C1RGD10 series
drives require heat sink kit 223-0355 when the continuous armature
current is above 5 ADC. MMRGD03 and C1RGD03 series drives
do not require an additional heat sink. Refer to Figure 6 (page 6)
for C1RGD heat sink mounting hole locations.
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 require fuses for protection. Use fast acting fuses
rated for 250 VAC or higher and approximately 150% of the
maximum armature current. Install a fuse on L1 if the input is 115
VAC. Fuse both L1 and L2 when the line voltage is 230 VAC. The
C1RGD drive is pre-wired with two internal 5A fuses (for C1RGD03
drives), or two 15A fuses (for C1RGD10 drives).
Table 1 lists the recommended line fuse sizes.

Speed adjust potentiometer installation
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 8). 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. (457 mm), use shielded cable. Keep speed
adjust potentiometer wires separate from power leads (L1, L2, A1,
A2).

Speed adjust potentiometer connections
MMRGD
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 9(a) on
page 16 for bidirectional operation. The motor should stop when
the wiper is in the center position. Turning the wiper CW from
center causes the motor to rotate in one direction, while turning the
wiper CCW from center causes rotation in the opposite direction.
Connect the speed adjust potentiometer as shown in Figure 9(b) on
page 16 for unidirectional operation in the forward direction.
Connect the speed adjust potentiometer as shown in Figure 9(c) on
page 16 for unidirectional operation in the reverse direction.
Refer to the Application Notes for additional speed adjust
potentiometer connections.
CIRGD
The speed adjust potentiometer is prewired for bidirectional
operation on C1RGD series drives. Reversing is accomplished by
setting the FWD/REV switch on the front panel to the desired
direction.

Connections
Warning
Do not connect this equipment with power applied.
Failure to heed this directive may result in fire or serious
injury.
When installing an MMRGD series drive, Minarik strongly
recommends the installation of a master power switch in
the voltage input line, as shown in Figure 10, page 19.
The switch contacts should be rated at a minimum of 200% of
motor nameplate current and 250 volts.
MMRGD
Connect the power input leads, an external line fuse and a DC
motor to TB501 on the drive’s printed circuit board (PCB) as shown
in Figure 10, page 19.
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.
Connect a DC motor to PCB terminals A1 and A2 as shown in
Figure 10, page 19. Ensure that the motor voltage rating is
consistent with the drive’s output voltage.

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 L1 terminal on the PCB. An additional line fuse should be
installed on L2 if the input voltage is 230 VAC. The line fuse(s)
should be rated at 250 volts and 150 - 200% of maximum motor
nameplate current. Refer to the line fuse chart on page 13 for fuse
ratings.

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 Connections section, page 17).
Line starting and stopping
When AC line voltage is applied to the drive, the motor accelerates
to the set speed. When AC line voltage is removed, the motor
coasts to a stop. Line stopping (removing AC line voltage) is
recommended for stopping in emergency situations only. It is not
recommended for frequent starting and stopping.

regeneratively brake at a rate controlled by the REV ACC trimpot.
Opening the switch will cause the motor to accelerate at a rate
controlled by the FWD ACC trimpot.
Twist logic wires and separate them from 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.

Calibration
RGD Series drives have eight user adjustable trimpots: MIN SPD,
MAX SPD, FWD TQ, REV TQ, IR COMP, FWD ACC, REV ACC,
and TACH. Each drive is factory calibrated to its maximum current
rating. Readjust the calibration trimpot settings to accommodate
lower current rated motors. See page 41 for calibration trimpot
layouts.
All adjustments increase with clockwise rotation (CW), and
decrease with counter-clockwise rotation (CCW) . Use a
non-metallic screwdriver for calibration. Each trimpot is identified on
the printed circuit board.

Minimum Speed (MIN SPD)
Note: The minimum speed feature applies only when the drive is
operating in unidirectional mode.
Note: Although the C1RGD drive is wired to operate bidirectional
mode, the minimum speed feature is still operational.
The MIN SPD setting determines the minimum speed that the
motor will rotate. It is factory set to zero speed.
To calibrate, set the speed adjust potentiometer full CCW. Adjust
the MIN SPD trimpot clockwise until the motor turns at the desired
minimum speed.
Maximum Speed (MAX SPD)
The MAX SPD setting determines the maximum motor speed that
the motor will rotate. It is factory set for maximum rated motor
speed.
To calibrate, set the speed adjust potentiometer full CW. Adjust the
MAX SPD trimpot clockwise until the motor turns at the desired
maximum speed.

Forward Torque (FWD TQ)
Warning
Although FORWARD TORQUE (FWD TQ) should be set to
115% of motor nameplate current rating, continuous operation
beyond this rating may damage the motor. If you intend to
operate beyond the rating, contact your Minarik representative
for assistance.
The FWD TQ setting determines the maximum torque for
accelerating and driving the motor in the forward direction. It also
sets the maximum torque for decelerating the motor in the reverse
direction. To recalibrate FWD TQ, refer to the recommended FWD
TQ settings in Figure 25, page 50, or use the following procedure:
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, voltage input signal, or
current input signal for maximum forward speed.
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 until the armature current
is 115% of the motor nameplate current rating.
7. Turn the speed adjust potentiometer (or voltage input signal or
current input signal to zero, if used) CCW until the motor stops.
8. Disconnect line power.
9. Remove the stall from the motor.

10. Remove the ammeter in series with the motor armature if it is
no longer needed.
If the time it takes to accelerate a load is too long due to the
forward torque setting, increase the forward torque setting to 130%
of rated motor current. The decision to change the forward torque
setting must be made after considering the gearbox and drivetrain
ratings, duty cycle, and motor characteristics.
Reverse Torque (REV TQ)
Warning
Although REVERSE TORQUE (REV TQ) is set to 115% of
motor nameplate current rating, continuous operation beyond
that rating may damage the motor. If you intend to operate
beyond the rating, contact your Minarik representative for
assistance.
The REV TQ setting determines the maximum torque for
accelerating and driving the motor in the reverse direction. It also
sets the maximum torque for decelerating in the forward direction.
To recalibrate REV TQ, refer to the recommended REV TQ settings
in Figure 25, page 50, or use the following procedure:

2. Set the REV TQ trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer, voltage input signal, or
current input signal for maximum reverse speed.
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 until the armature current
is 115% of motor nameplate current rating.
7. Turn the speed adjust potentiometer (or voltage input signal or
current input signal, to zero if used) CCW until the the motor
stops.
8. Disconnect line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is
no longer needed.
If the time it takes to accelerate a load is too long due to the
reverse torque setting, increase the reverse torque setting to 130%
of rated motor current. The decision to change the reverse torque
setting must be made after considering the gearbox and drivetrain
ratings, duty cycle, and motor characteristics.

Calibration
IR Compensation (IR COMP)
The IR COMP setting (also known as Regulation) determines the
degree to which motor speed is held constant as the motor load
changes. It is factory set for optimum motor regulation.
Recalibrate the IR COMP setting when using a lower current rated
motor. See Figure 25, page 50, for typical IR COMP settings, or
recalibrate using the following procedure:
1. Set the IR COMP trimpot to minimum (full CCW).
2. Rotate the speed adjust potentiometer until the motor runs at
midspeed without load (for example, adjust to 900 RPM for an
1800 RPM motor). A handheld 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 drive.
5. Unload the motor.

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.

Tachogenerator (TACH)
NOTE: 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 on terminal block
S0502. The polarity is + for T1 and – for T2 when the motor
running in the forward direction.
2. Set switch SW504 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 SW504 to TACH for tachogenerator feedback.
6. Set the IR COMP trimpot full CCW.
7. Set the TACH trimpot full CW.
8. Set the speed adjust potentiometer full CW.
9. 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 set speed when SW504 is set to either
armature or tachogenerator feedback

-PCM Only: Signal Adjustment (SIGNAL
ADJUST)
The SIGNAL ADJUST trimpot establishes the motor speed
obtained in response to the maximum input signal.
To calibrate the SIGNAL ADJUST pot:
1. Adjust the MAX SPD trimpot full CW.
2. Apply the maximum signal.
3. Adjust the SIGNAL ADJUST trimpot until the motor runs at
the desired speed.
To Switch directions, short TB501-4, DIR, to TB501-3, COM. This
inverts the signal to the MMRGD. Use a relay contact, switch or
jumper to change directions.
