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. Make sure you read and understand the Safety
Precautions on page i before attempting to install this product.
Heat Sinking
Chassis
Model MM23002D requires 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.
NEMA 1
Models MM23102D and MM23202D require an additional heat sink
when the continuous armature current is above 5 amps. Use Minarik
Drives heat sink kit part number 223-0174. All other NEMA 1 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.
NEMA 4X
All NEMA 4X models come with the heat sink already attached.
Therefore, all NEMA 4X drives have sufficient heat sinking in their basic
configuration.

MM23xx2D Series
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.

Speed Adjust Potentiometer

!
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.
14
MM23xx2D 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.
15
MM23xx2D 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 on page 17 lists the recommended
line fuse sizes.
Cased models come with preinstalled fuses. Models MM23102D,
MM23202D and MM23402D are preinstalled with 15 amp fuses. Models
MM23112D, MM23212D and MM23412D are preinstalled with 3 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
on page 17 to install a lower rated fuse.
Refer to Table 2 on page 17 for Short Circuit Current Ratings (SCCR).

WARNING!
Do not connect this equipment with power applied. Failure to
heed this warning may result in fire, explosion, or serious injury.
Minarik Drives strongly recommends the installation of a
master power switch in the voltage input line, as shown in
Figure 9 (page 21). The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250 volts.
This power switch is provided with NEMA 1 and NEMA 4X models.
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 9 on page 21.
For enclosed models, connect the AC line power leads to screw terminals
1 (L1) and 2 (L2 115) if using a 115 VAC line or to terminals 1 (L1) and 3 (L2
230) if using a 230 VAC line. Refer to Figure 10 on page 22.
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.
For chassis models, connect a DC motor to terminals A1 and A2 as shown
in Figure 9 on page 21. For enclosed models, connect a DC motor to
terminals 5 (A1) and 4 (A2) as shown in Figure 10 on page 22. Ensure that
the motor voltage rating is consistent with the drive’s output voltage.
18
MM23xx2D Series
Speed Adjust Potentiometer
For chassis models, use a 10K ohm, 1/4 W potentiometer for speed
control. Connect the counter-clockwise end of the potentiometer to S1,
the wiper to S2, and the clockwise end to S3. If the potentiometer works
inversely of the desired functionality (e.g. to increase motor speed you
must turn the potentiometer counterclockwise), power off the drive and
swap the S1 and S3 connections. Refer to Figure 9 on page 21.
For enclosed models, the speed adjust potentiometer is factory installed
and prewired.
19
MM23xx2D Series
Analog Input Signal
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 8). Connect the signal common (–) to S1. Connect the signal
reference (+) to S2. Make no connection to S3. 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.
An analog input voltage range of 0–2.5 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.

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 51, for further assistance.
Before Applying Power
1. Verify that no foreign conductive material is present on the
printed circuit board.
2. Ensure that all switches and jumpers are properly set.

Starting and Stopping Methods

!
WARNING!
Dynamic 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 9
on page 21).
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
inhibit is not active.
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.
29
MM23xx2D Series
Dynamic Braking

!
WARNING!
Wait for the motor to completely stop before switching back to
RUN. This will prevent high armature currents from damaging
the motor or drive.
Dynamic braking may be used to rapidly stop a motor (Figure 14 on page
31). For the RUN/BRAKE switch, use a two pole, two position switch
rated for at least the armature voltage rating and 150% of the armature
current rating. For the dynamic brake resistor, use a 40 watt minimum,
high power, wirewound resistor.
Sizing the dynamic brake resistor depends on load inertia, motor voltage,
and braking time. Use a lower-value, higher-wattage dynamic brake
resistor to stop a motor more rapidly. Refer to Table 3 on page 31 for
recommended dynamic brake resistor sizes.
Note: Models MM23202D and MM23212D incorporate dynamic
braking in their designs.

Inhibit Terminals
Activate the INHIBIT to coast the motor to minimum or zero speed (see
Figure 15 for INHIBIT terminal location). Deactivate the INHIBIT terminals
to accelerate the motor to set speed. See Figure 16 on page 34 for jumper
J501 and J502 configuration, which determines if the INHIBIT is normally
open or normally closed to run. The INHIBIT function will work the same
way in Speed or Torque Mode.
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.
Minarik Drives offers two accessory plug harnesses for connecting to
the INHIBIT terminals: part number 201-0024 [plug with 18 in. (46 cm)
leads]; and part number 201-0079 [plug with 36 in. (91 cm) leads].

Decelerating to Minimum Speed
The switch shown in Figure 17 may be used to decelerate a motor to
a minimum speed. Closing the switch between S1 and S2 decelerates
the motor from set speed to a minimum speed determined by the
MIN SPD trim pot setting. If the MIN SPD trim pot is set full CCW, the
motor decelerates to zero speed when the switch between S1 and S2 is
closed. The DECEL trim pot setting determines the rate at which the drive
decelerates. By opening the switch, the motor accelerates to set speed at
a rate determined by the ACCEL trim pot setting.


!
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.
MM23xx2D 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.
35
MM23xx2D Series
Minimum Speed (MIN SPD)
The MIN SPD setting determines the minimum motor speed when the
speed adjust potentiometer or input voltage signal is set for minimum
speed. It is factory set for zero speed.
To calibrate the MIN SPD:
1.
Set the MIN SPD trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage signal for
minimum speed.
3.
Adjust MIN SPD until the desired minimum speed is reached or
is just at the threshold of rotation.
Maximum Speed (MAX SPD)
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.
Note: Check the MIN SPD and MAX SPD adjustments after recalibrating
to verify that the motor runs at the desired minimum and maximum
speed.
36
MM23xx2D Series
Torque (TORQUE)

!
WARNING!
TORQUE should be set to 150% 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 TORQUE setting determines the maximum torque for accelerating
and driving the motor. To calibrate TORQUE, refer to the recommended
TORQUE settings in Figure 18 on page 39 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 TORQUE 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 TORQUE trim pot CW until the armature
current is 150% 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.
37
MM23xx2D 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 39 for recommended IR COMP settings.

Acceleration (ACCEL)
The ACCEL setting determines the time the motor takes to ramp to a
higher speed. See Specifications on page 1 for approximate acceleration
times. ACCEL is factory set for the shortest acceleration time (full CCW).
To set the acceleration time:
1.
Set the speed adjust potentiometer or input voltage signal for
minimum speed. The motor should run at minimum speed.
2.
Set the speed adjust potentiometer or input voltage signal for
maximum speed. Measure the time it takes the motor to go
from minimum to maximum speed.
3. If the time measured in step 2 is not the desired acceleration
time, turn the ACCEL trim pot CW for a longer acceleration time
or CCW for a shorter acceleration time. Repeat steps 1 through
2 until the acceleration time is correct.
Deceleration (DECEL)
The DECEL setting determines the time the motor takes to ramp to a
lower speed. See Specifications on page 1 for approximate deceleration
times. DECEL is factory set for the shortest deceleration time (full CCW).
To set the deceleration time:
1.
Set the speed adjust potentiometer or input voltage signal for
maximum speed. The motor should run at maximum speed.
2. Set the speed adjust potentiometer or input voltage signal for
minimum speed. Measure the time it takes the motor to go
from maximum to minimum speed.
3. If the time measured in step 2 is not the desired deceleration
time, turn the DECEL trim pot CW for a longer deceleration time
or CCW for a shorter deceleration time. Repeat steps 1 through
2 until the deceleration time is correct.

Unconditional Warranty
A. Warranty
Minarik Drives warrants that its products will be free from defects in workmanship and material
for twelve (12) months or 3000 hours, whichever comes first, from date of manufacture thereof.
Within this warranty period, Minarik Drives will repair or replace, at its sole discretion, such
products that are returned to Minarik Drives, 14300 De La Tour Drive, South Beloit, Illinois 61080
USA.
This warranty applies only to standard catalog products, and does not apply to specials. Any
returns of special controls will be evaluated on a case-by-case basis. Minarik Drives is not
responsible for removal, installation, or any other incidental expenses incurred in shipping the
product to and from the repair point.
B. Disclaimer
The provisions of Paragraph A are Minarik Drives’s sole obligation and exclude all other
warranties of merchantability for use, expressed or implied. Minarik Drives further disclaims
any responsibility whatsoever to the customer or to any other person for injury to the person
or damage or loss of property of value caused by any product that has been subject to misuse,
negligence, or accident, or misapplied or modified by unauthorized persons or improperly
installed.
C. Limitations of Liability
In the event of any claim for breach of any of Minarik Drives’s obligations, whether expressed
or implied, and particularly of any other claim or breach of warranty contained in Paragraph
A, or of any other warranties, expressed or implied, or claim of liability that might, despite
Paragraph B, be decided against Minarik Drives by lawful authority, Minarik Drives shall under no
circumstances be liable for any consequential damages, losses, or expenses arising in connection

only.
If for any reason any of the foregoing provisions shall be ineffective, Minarik Drives’s liability
for damages arising out of its manufacture or sale of equipment, or use thereof, whether such
liability is based on warranty, contract, negligence, strict liability in tort, or otherwise, shall not in
any event exceed the full purchase price of such equipment.

under any law applicable to the sale of equipment or the use thereof, must be commenced within
one year after the cause of such action arises.
