Section 1. 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 I,
and also in Quadrant III if
the drive is reversible (see
Figure 1). 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.
Quadrant II
Quadrant I
Quadrant III
Quadrant IV
MOTOR
ROTATION
MOTOR
TORQUE
NOTE: ARROWS IN SAME DIRECTION = MOTOR ACTION
ARROWS IN OPPOSITE DIRECTION = REGENERATIVE ACTION
Regenerative drives operate
in two additional quadrants:
Quadrant II and Quadrant
Figure 1. Four Quadrant Operation
IV. In these quadrants,
motor torque is in the
opposite direction of motor rotation.
This allows regenerative drives to reverse a motor without contractors
or switches, to control an overhauling load, and to decelerate a load
faster than it would to coast to a lower speed.

or serious injury. Make sure you read and understand the Safety
Precautions on page i before attempting to install this product.
Heat Sinking
Chassis
Models MMRGD10-D230AC and MMRGD10-D230AC-PCM require an
additional heat sink when the continuous armature current is above 5
amps. Use Minarik Drives heat sink kit part number 223-0159. All other
chassis drives have sufficient heat sinking in their basic configuration.
Use a thermally conductive heat sink compound (such as Dow Corning®
340 Heat Sink Compound) between the chassis and the heat sink surface
for optimum heat transfer.

Mounting
Chassis
• Drive components are sensitive to electrostatic discharge. Avoid
direct contact with the circuit board. Hold the drive by the chassis
or heat sink only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminals and calibration
trim pots.
• 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 the drive with its board in either a horizontal or vertical
plane. Eight 0.19” (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 surface and to reach bare metal.

!
WARNING!
Be sure that the potentiometer tabs do not make contact with the
potentiometer’s body. Grounding the input will cause damage to
the drive.
If using a remote potentiometer with a chassis drive, mount the speed
adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware
provided (Figure 7). 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 the speed adjust potentiometer wires are longer than
18 in. (46 cm), use shielded cable. Keep the speed adjust potentiometer
wires separate from power leads (L1, L2, A1, A2).

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.
This product does not have internal solid state motor overload
protection. It does not contain speed-sensitive overload
protection, thermal memory retention or provisions to receive
and act upon signal from remote devices for over temperature
protection. If motor over protection is needed in the end-use
product, it needs to be provided by additional equipment in
accordance with NEC standards.
• Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for
AC line and motor wiring.
13
RGD Series
Shielding Guidelines

!
WARNING!
Under no circumstances should power and logic level leads be
bundled together. Induced voltage can cause unpredictable
behavior in any electronic device, including motor controls.
As a general rule, Minarik Drives recommends shielding of all conductors.
If it is not practical to shield power conductors, it is recommended
to shield 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.
14
RGD Series
Line Fusing
Chassis drives should be fused for protection. Use fast acting fuses rated
for 250 VAC or higher and 150% of maximum armature current. Fuse HOT
L1 only when the line voltage is 115 VAC. Fuse both L1 and L2 when the
line voltage is 230 VAC. Table 1 lists the recommended line fuse sizes.
Cased models come with preinstalled fuses. Model C1RGD03-D230AC is
preinstalled with 5 amp fuses. Model C1RGD10-D230AC is preinstalled
with 15 amp fuses.
Preinstalled line fuses are rated for maximum horsepower. If the
horsepower rating of the motor being used is less than the maximum
horsepower rating of the drive, the line fuse may have to be replaced
with a lower rated one. Fuses should be rated for 250 VAC or higher and
approximately 150% of the maximum armature current. Refer to Table 1
to install a lower rated fuse.

Connections

!
Do not connect this equipment with power applied. Failure to
heed this warning may result in fire, explosion, or serious injury.
WARNING!
Minarik Drives strongly recommends the installation of a
master power switch in the voltage input line, as shown in
Figure 8 (page 17). The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250 volts.
Power Input
For chassis models, connect the AC line power leads to terminals L1 and
L2. Minarik Drives recommends the use of a single-throw, double-pole
master power switch. The switch should be rated at a minimum of 250
volts and 200% of motor current. Refer to Figure 8 on page 17.
For enclosed models, connect the AC line power leads to terminals L1
and L2(115) if using a 115 VAC line or to terminals L1 and L2(230) if using
a 230 VAC line. Refer to Figure 9 on page 17.
Motor
Drives supply motor armature 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 the motor does not
spin in the desired direction, remove power and reverse the A1 and A2
connections.
Connect a DC motor to terminals A1 and A2. For chassis models, refer to
Figure 8 on page 17. For enclosed models, refer to Figure 9 on page 17.
Ensure that the motor voltage rating is consistent with the drive’s output
voltage.

Speed Adjust Potentiometer
For chassis drives, use a 10K ohm, 1/4 W potentiometer for speed control.
The motor can operate in one direction (unidirectional) or two directions
(bidirectional) depending on how the speed adjust potentiometer is
connected to the drive.
For unidirectional operation in the foward direction, connect the speed
adjust potentiometer as shown in Figure 10(a).
For unidirectional operation in the reverse direction, connect the speed
adjust potentiometer as shown in Figure 10(b).
For bidirectional operation, connect the speed adjust potentiometer
as shown in Figure 10(c). The motor does not operate when the
potentiometer is in the center position. Turning the potentiometer
clockwise (CW) from the center position causes the motor to rotate in
the forward direction, while turning the potentiometer counterclockwise
(CCW) causes rotation in the reverse direction.
For enclosed models, the speed adjust potentiometer is factory installed
and prewired for unidirctional operation. Use the Forward/Reverse
switch on the front cover to determine motor direction.

Analog Input Signal (non -PCM models)
Instead of using a speed adjust potentiometer, the drive may be wired to
follow an analog input voltage signal that is isolated from earth ground
(Figure 11). Connect the signal common (–) S0. Connect the signal input
(+) to S2. A potentiometer can be used to scale the analog input voltage.
An interface device, such as Minarik Drives model PCM4, may be used to
scale and isolate an analog input voltage.

Instead of using a speed adjust potentiometer, the drive may be wired
to follow an analog input voltage signal that is isolated or non-isolated
(Figure 12). Connect the signal common (–) to terminal NEG. Connect the
signal input (+) to terminal POS. A potentiometer can be used to scale the
analog input voltage.
An analog input voltage range of 0 - 10 VDC is required to produce
an armature voltage range of 0 - 90 VDC with 115 VAC line voltage or
0 - 180 VDC with 230 VAC line voltage. To change direction, use the
direction switch.

Direction Switch
For MMRGD models, refer to Section 7. Application Notes on page 38 for
wiring a direction switch.
For MMRGD-PCM models, a single-pole, single-throw switch can be used
as a reversal switch. Connect the switch to terminals COM and DIR. Close
the switch to reverse the motor. Open the switch to return the motor
back to it’s original direction. Connections can be made to the spade
terminals or to cage clamp terminal TB501. Refer to Figure 12 on page
20.
For enclosed models, the direction switch is factory installed on the front
cover.
Enable, Regen Brake, and Inhibit
See the “Starting and Stopping Methods” section on pages 25 through
29 for a detailed description of the Enable, Inhibit, and Regen Braking
connections.
Tachogenerator Feedback
Using tachogenerator feedback improves speed regulation from
approximately 1% of motor base speed to approximately 0.1% of motor
base speed. Use tachogenerators rated from 7 VDC per 1000 RPM to 50
VDC per 1000 RPM. Connect the tachogenerator to terminals T1 and T2
of terminal block TB501. The polarity is positive (+) for T1 and negative
(-) for T2 when the motor is running in the forward direction. Place
SW503 in the TACH position. The TACH trim pot must be adjusted prior to
operating with tachogenerator feedback. Refer to the Calibration section
for instructions on calibrating the TACH trim pot.

Section 5. Operation

!
WARNING!
Change voltage switch settings only when the drive is
disconnected from AC line voltage. Make sure both switches are
set to their correct position. If the switches are improperly set
to a lower voltage position, the motor will not run at full voltage
and may cause damage to the transformer. If the switches are
improperly set to a higher voltage position, the motor will
overspeed, which may cause motor damage, or result in bodily
injury or loss of life.
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.
If the motor or drive does not perform as described, disconnect
the AC line voltage immediately. Refer to the Troubleshooting
section, page 47, for further assistance.
Before Applying Power
1. Verify that no foreign conductive material is present on the
printed circuit board.
2.

Starting and Stopping Methods

!
WARNING!
Regenerative braking, coasting to a stop, or decelerating to
minimum speed 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 lines) is the only acceptable method for emergency
stopping.
For this reason, Minarik Drives strongly recommends installing
an emergency stop switch on both AC line inputs (see Figure 8
on page 17).
Frequent starting and stopping can produce 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 the
Enable, Regen Brake, and Inhibit are open.
Line Starting and Stopping
Line starting and stopping (applying and removing AC line voltage) is
recommended for infrequent starting and stopping of a drive only. When
AC line voltage is applied to the drive, the motor accelerates to the speed
set by the speed adjust potentiometer or analog signal. When AC line
voltage is removed, the motor coasts to a stop.
25
RGD Series
Inhibit - Regenerative Brake to Zero Speed
Short the inhibit terminals RB1/COM and RB3 to regeneratively brake
the motor to zero speed (see Figure 14). The inhibit bypasses both the
MIN SPD trim pot and the deceleration rate set by the FWD ACC or REV
ACC trim pots. Open the inhibit terminals to accelerate the motor to set
speed.
On -PCM models, either the spade lug or cage clamp terminals can be
used.
Twist inhibit wires and separate them from power-carrying wires or
sources of electrical noise. Use shielded cable if the inhibit wires are
longer than 18 inches (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.

Section 6. Calibration

!
WARNING!
Dangerous voltages exist on the drive when it is powered. When
possible, disconnect the voltage input from the drive before
adjusting the trim pots. If the trim pots 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.
MMRGD series drives have user-adjustable trim pots. Each drive is
factory calibrated to its maximum current rating. Readjust the calibration
trim pot settings to accommodate lower current rated motors.
All adjustments increase with CW rotation, and decrease with CCW
rotation. Use a non-metallic screwdriver for calibration. Each trim pot is
identified on the printed circuit board.
30
RGD Series
Minimum Speed (MIN SPEED)
The MIN SPD setting determines the minimum motor speed in
unidirectional operation when the speed adjust potentiometer or input
voltage or current signal is set for minimum speed.
To calibrate the MIN SPD:
1.
Set the speed adjust potentiometer or input voltage signal for
minimum speed.
2.
Adjust MIN SPD until the desired minimum speed is reached or
is just at the threshold of rotation.
Maximum Speed (MAX SPEED)
The MAX SPD setting determines the maximum motor speed when the
speed adjust potentiometer or input voltage signal is set for maximum
speed.
To calibrate MAX SPD:
1.
Set the MAX SPD trim pot full CCW.
2.
Set the speed adjust potentiometer or input voltage signal for
maximum speed.
3. Adjust MAX SPD until the desired maximum speed is reached.
If using a -PCM model, set the MAX SPD trim pot fully CW.
31
RGD Series
Forward Torque (FWD TQ)

!
WARNING!
FWD TQ should be set to 120% 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 Drives representative for assistance.
The FWD TQ setting determines the maximum torque for accelerating
and driving the motor in the forward direction. To calibrate FWD TQ,
refer to the recommended FWD TQ settings in Figure 18 on page 35 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 trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer full CW or input voltage
signal to maximum 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 trim pot CW until the armature
current is 120% of motor rated armature current.
7. Turn the speed adjust potentiometer CCW or decrease the
input voltage signal.
8. Remove 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.
32
RGD Series
Reverse Torque (REV TQ)

!
WARNING!
REV TQ should be set to 120% 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
Drives representative for assistance.
The REV TQ setting determines the maximum torque for accelerating and
driving the motor in the reverse direction. To calibrate REV TQ, refer to
the recommended REV TQ settings in Figure 18 on page 35 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 REV TQ trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer full CW or input voltage
signal to maximum 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 trim pot CW until the armature
current is 120% of motor rated armature current.
7. Turn the speed adjust potentiometer CCW or decrease the
input voltage signal.
8. Remove 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.
33
RGD Series
IR Compensation (IR COMP)
The IR COMP setting determines the degree to which motor speed is held
constant as the motor load changes.
Use the following procedure to recalibrate the IR COMP setting:
1.
Set the IR COMP trim pot to minimum (full CCW).
2. Increase the speed adjust potentiometer or input voltage signal
until the motor runs at midspeed without load (for example,
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 trim
pot until the motor runs at the speed measured in step 2. If
the motor oscillates (overcompensation), the IR COMP trim pot
may be set too high (CW). Turn the IR COMP trim pot CCW to
stabilize the motor.
5. Unload the motor.
See Figure 18 on page 35 for recommended IR COMP settings.

Tachogenerator (TACH)

!
Calibrate the TACH setting only when a tachogenerator is used.
WARNING!
The TACH setting, like IR COMP setting, determines the degree to which
motor speed is held constant as the motor load changes. To calibrate
the TACH trim pot:
1. Connect the tachogenerator to T1 and T2. The polarity is
positive (+) for T1 and negative (-) for T2 when the motor is
running in the forward direction.
2.
Set the feedback select switch SW503 to ARM for armature
feedback.
3.
Set the speed adjust potentiometer or input voltage signal to
maximum forward speed. Measure the armature voltage across
A1 and A2 using a voltmeter.
4.
Set the speed adjust potentiometer or input voltage signal to
zero speed.
5.
Set SW503 to TACH for tachogenerator feedback.
6.
Set the IR COMP trim pot to full CCW.
7.
Set the TACH VOLTS trim pot to full CW.
8.
Set the speed adjust potentiometer or input voltage signal to
maximum forward speed.
9.
Adjust the TACH trim pot until the armature voltage is the same
value as the voltage measured in step 3.
Check that the TACH is properly calibrated. The motor should run at the
same set speed when SW503 is set to either ARM or TACH.
36
Minarik Drives offers two accessory plug harnesses for connecting to the
TACH terminals: part number 201-0024 [plug with 18 in. (46 cm) leads];
and part number 201-0079 [plug with 36 in. (91 cm) leads].
RGD Series
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 trim pot CW to increase the forward acceleration
time, and CCW to decrease the forward acceleration time.
Reverse Acceleration (REV ACC)
