Mounng
• 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.

Shielding Guidelines
Under no circumstances should power and logic level leads be
!
As a general rule, Minarik Drives recommends shielding of all conductors.
If it is not praccal to shield power conductors, it is recommended
to shield all logic-level leads. If shielding of all logic-level leads is not
praccal, 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 connues to pick up noise aer grounding the shield, it may
be necessary to add AC line ltering devices, or to mount the drive in a
less noisy environment.
Logic wires from other input devices, such as moon controllers and PLL
velocity controllers, must be separated from power lines in the same
manner as the logic I/O on this drive.
bundled together. Induced voltage can cause unpredictable
behavior in any electronic device, including motor controls.

Line Fusing
Models MM03-115AC-PCM and MM10-115AC-PCM are preinstalled
with one line fuse in fuse holder FU501. Models MM03-230AC-PCM and
MM10-230AC-PCM are preinstalled with two line fuses in fuse holders
FU501 and FU502.
Models MM10-115AC-PCM and MM10-230AC-PCM are preinstalled
with 15 amp fuses. Models MM03-115AC-PCM and MM03-230AC-PCM
are preinstalled with a 5 amp fuse.
Preinstalled line fuses are rated for maximum horsepower. If the
horsepower rang of the motor being used is less than the maximum
horsepower rang 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.

Power Input
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 5 on page 16.
Motor
Drives supply motor armature voltage from A1 and A2 terminals. It is
assumed throughout this manual that, when A1 is posive with respect
to A2, the motor will rotate clockwise (CW) while looking at the output
sha protruding from the front of the motor. If the motor does not
spin in the desired direcon, remove power and reverse the A1 and A2
connecons.
Connect a DC motor to terminals A1 and A2 as shown in Figure 5 on page
16. Ensure that the motor voltage rang is consistent with the drive’s
output voltage.

See page 24 for a detailed explanaon of the Run/Stop switch. If no Run/
Stop switch is desired, a jumper must be placed between terminals 1 and
2 (factory preinstalled).
Inhibit Switch
See page 23 for a detailed explanaon of the Inhibit switch.
Speed Adjust Potenometer
Use a 10K ohm, 1/4 W potenometer for speed control. Connect the
counter-clockwise end of the potenometer to S1, the wiper to S2, and
the clockwise end to S3. If the potenometer works inversely of the
desired funconality (e.g. to increase motor speed you must turn the
potenometer counterclockwise), power o the drive and swap the S1
and S3 connecons. Refer to Figure 5 on page 16.
Analog Input Signal
Instead of using a speed adjust potenometer, the drive may be wired
to follow an analog input voltage or current signal that is either isolated
or non-isolated from earth ground. Connect the signal common (-) to S1.
Connect the signal reference (+) to S2.
Refer to Figure 6 on page 18 for switch SW501 sengs and locaon.
An analog input voltage range of 0–10 VDC or 4–20 mA 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.

a drive that is malfunconing. 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 5
on page 16).
Frequent starng and stopping can produce high torque. This
may cause damage to motors, especially gearmotors that are not
properly sized for the applicaon.

Dynamic Braking
Wait for the motor to completely stop before switching back to
RUN. This will prevent high armature currents from damaging
!
Dynamic braking may be used to rapidly stop a motor (Figure 7 on page
22). For the RUN/BRAKE switch, use a two pole, two posion switch
rated for at least the armature voltage rang and 150% of the armature
current rang. For the dynamic brake resistor, use a 40 wa minimum,
high power, wirewound resistor.
Sizing the dynamic brake resistor depends on load inera, motor voltage,
and braking me. Use a lower-value, higher-waage dynamic brake
resistor to stop a motor more rapidly. Refer to Table 3 on page 22 for
recommended dynamic brake resistor sizes.

Run/Stop Switch
The Run/Stop switch may be used to decelerate a motor to a minimum
speed. Opening the Run/Stop switch decelerates the motor from set
speed to a minimum speed determined by the MIN OUT trim pot seng.
If the MIN OUT trim pot is set to zero speed, the motor decelerates to
zero speed when the Run/Stop switch is opened. The DECEL trim pot
seng determines the rate at which the drive decelerates. By closing the
Run/Stop switch, the motor accelerates to set speed at a rate determined
by the ACCEL trim pot seng. See Figure 5 on page 16 for switch locaon
and wiring.
NOTE: If no run/stop switch is used, a jumper must be placed between
terminals 1 and 2 (factory preinstalled).

Minimum Speed (MIN OUT)
The MIN OUT seng determines the minimum motor speed when the
speed adjust potenometer or input voltage or current signal is set for
minimum speed. It is factory set for zero speed.
To calibrate the MIN OUT:
1. Set the speed adjust potentiometer or input voltage or current
signal for minimum speed.
2. Adjust MIN OUT until the desired minimum speed is reached or
is just at the threshold of rotation.
Maximum Speed (MAX SPD)
The MAX SPD seng determines the maximum motor speed when the
speed adjust potenometer or input voltage or current signal is set for
maximum speed.
To calibrate MAX SPD:
1. Set the speed adjust potentiometer or input voltage or current
signal for maximum speed.
2 . Adjust MAX SPD until the desired maximum speed is reached.
Note: Check the MIN out and MAX SPD adjustments aer recalibrang
to verify that the motor runs at the desired minimum and maximum
speed.

ammeter in series with the armature.
2. Set the TORQUE LIMIT 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 LIMIT 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.

IR Compensaon (IR COMP)
The IR COMP seng determines the degree to which motor speed is held
constant as the motor load changes.
Use the following procedure to recalibrate the IR COMP seng:
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 9 on page 29 for recommended IR COMP sengs.

Acceleraon (ACCEL)
The ACCEL seng determines the me the motor takes to ramp to a
higher speed. See Specicaons on page 1 for approximate acceleraon
mes. ACCEL is factory set for the shortest acceleraon me (full CCW).
To set the acceleraon me:
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.
Deceleraon (DECEL)
The DECEL seng determines the me the motor takes to ramp to a
lower speed. See Specicaons on page 1 for approximate deceleraon
mes. DECEL is factory set for the shortest deceleraon me (full CCW).
To set the deceleraon me:
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
