Models MM10-115AC-PCM and MM10-230AC-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®...
MM-PCM Series Mounting • 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.
MM-PCM Series Speed Adjust Potentiometer Be sure that the potentiometer tabs do not make contact with the potentiometer’s body. Grounding the input will cause damage to the drive. WARNING! If using a remote potentiometer with a chassis drive, mount the speed adjust potentiometer through a 0.38 in.
MM-PCM Series Wiring 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. WARNING! 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.
WARNING! 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.

MM-PCM Series Short-circuit current rating (SCCR) is the maximum short-circuit current that the speed control can safely withstand when protected by a specific over-current protective device(s). WARNING! Table 2. Short Circuit Current Ratings Short Circuit Maximum Drive Model Current Rating...
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 WARNING! power switch in the voltage input line, as shown in Figure 5 (page 16).
MM-PCM Series 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.
MM-PCM Series Field Output Connections The field output is for shunt wound motors only. Do not make any connections to F1 and F2 when using a permanent magnet motor. WARNING! See Table 2 for field output connections. Use 14 - 16 AWG wire to connect the field output to a field / shunt wound motor.
MM-PCM Series Run/Stop Switch See page 24 for a detailed explanation 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 explanation of the Inhibit switch.
MM-PCM Series 5 1 ( L " " 1 0 K O H M R U N S / T P SIGNAL CONNECTIONS ON TOP “LOGIC” BOARD NOTE: DO NOT make any connections to F1 and F2 if using a permanent magnet motor.
MM-PCM Series Section 4. Operation 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 WARNING! and may cause damage to the transformer.
MM-PCM Series Select Switches Signal Select Switch (SW501) Set the signal select switch SW501 to either CURR to use a current input signal or VOLT to use a voltage input signal or potentiometer. See Figure V O L T C R R...
MM-PCM Series Startup Turn the speed adjust potentiometer full counterclockwise (CCW) or set the input voltage or current signal to minimum. Apply AC line voltage. Slowly advance the speed adjust potentiometer clockwise (CW) or increase the input voltage or current signal. The motor slowly accelerates as the potentiometer is turned CW or as the input voltage or current signal is increased.
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).
MM-PCM Series Dynamic Braking Wait for the motor to completely stop before switching back to RUN. This will prevent high armature currents from damaging the motor or drive. WARNING! Dynamic braking may be used to rapidly stop a motor (Figure 7 on page 22).
MM-PCM Series Table 3. Minimum Recommended Dynamic Brake Resistor Values Motor Armature Voltage Dynamic Brake Resistor Value 90 VDC 15 ohms 180 VDC 30 ohms For motors rated 1/17 horsepower and lower, a brake resistor is not necessary since the armature resistance is high enough to stop the motor without demagnetization.
MM-PCM Series Inhibit Switch Connect an inhibit switch as shown in Figure 8A or 8B. Activating the inhibit circuit causes the motor to coast to a stop. Deactivating the inhibit circuit accelerates the motor to set speed at a rate controlled by the ACCEL trim pot.
MM-PCM Series 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 setting.
BE ALERT. High voltages can cause serious or fatal injury. MM-PCM 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.
MM-PCM Series Minimum Speed (MIN OUT) The MIN OUT setting determines the minimum motor speed when the speed adjust potentiometer or input voltage or current signal is set for minimum speed. It is factory set for zero speed. To calibrate the MIN OUT: Set the speed adjust potentiometer or input voltage or current signal for minimum speed.
Continuous operation beyond this rating may damage the motor. If you intend to operate beyond the rating, contact your WARNING! Minarik Drives representative for assistance. The TORQUE LIMIT setting determines the maximum torque for accelerating and driving the motor. To calibrate TORQUE LIMIT, refer to...
MM-PCM 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: Set the IR COMP trim pot to minimum (full CCW).
MM-PCM Series 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: Set the speed adjust potentiometer or input voltage signal for minimum speed.
MM-PCM Series Section 6.Application Notes Multiple Fixed Speeds Replace the speed adjust potentiometer with a series of resistors with a total series resistance of 10K ohms (Figure 10). Add a single pole, multi- position switch with the correct number of positions for the desired number of fixed speeds.
MM-PCM Series Adjustable Speeds Using Potentiometers In Series Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in series with a total series resistance of 10K ohms. Figure 11 shows a connection for high and low speed adjust potentiometers.
MM-PCM Series Independent Adjustable Speeds Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in series with a total series resistance of 10K ohms. Figure 12 shows a connection for high and low speed adjust potentiometers.
MM-PCM Series RUN/JOG Switch - Inhibit Connection Using a RUN/JOG switch is recommended in applications where quick stopping is not needed and frequent jogging is required. Use a single pole, two position switch for the RUN/JOG switch, and a single pole, normally closed, momentary operated pushbutton for the JOG pushbutton.
MM-PCM Series RUN/JOG Switch - Potentiometer Connection Connect the RUN/JOG switch and the JOG pushbutton as shown in Figure 14. When the RUN/JOG switch is set to JOG, the motor decelerates to minimum speed (minimum speed is determined by the MIN OUT trim pot setting).
MM-PCM Series Leader-Follower Application In this application, use a PCM4 to monitor the speed of the leader motor (Figure 15). The PCM4 isolates the leader motor from the follower drive, and outputs a voltage proportional to the leader motor armature voltage.
MM-PCM Series Single Speed Potentiometer Control Of Multiple Drives Multiple drives can be controlled with a single speed adjust potentiometer using a USIM-8 at the input of each drive to provide isolation (Figure 16). Optional ratio potentiometers can be used to scale the USIM-8 output voltage, allowing independent control of each drive.
MM-PCM Series Reversing A dynamic brake may be used when reversing the motor direction (Figure 17). Use a three pole, three position switch rated for at least the maximum DC armature voltage and maximum braking current. Wait for the motor to stop completely before switching it to either the forward or reverse direction.
MM-PCM Series Section 7. Diagnostic LEDs MM-PCM series drives are equipped with four diagnostic LEDs: • Current Limit (C/LIM): Red LED lights whenever the drive reaches current limit. • Inhibit (INH): Red LED lights whenever the inhibit circuit is active.
Check that the selection switch settings are correctly set. Check that the drive’s rated armature is consistent with the motor ratings. For additional assistance, contact your local Minarik Drives distributor or the factory direct: (800) MINARIK or FAX: (800) 394-6334...
