Page 9: Installation
Installation Mounting • Drive components are sensitive to electrostatic fields. Avoid contact with the circuit board directly. Hold drive by the chassis only. • Protect the drive from dirt, moisture, and accidental contact. Provide sufficient room for access to the terminal block and calibration trimpots. -
Page 10: Wiring
Installation 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. This drive is isolated from earth ground. Circuit potentials are at 115 above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements. - Page 11 Induced voltage can cause unpredictable behavior 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 is not practical, the user should twist all logic leads with themselves to minimize induced noise.

Compound) between the drive chassis and heat sink surface for optimum heat transfer. Line fusing Protect all PCMXP Series drives with AC line fuses. Use fast acting AC line fuses rated for 250 volts, and approximately 150% to 200% of the maximum armature current. Fuse only the “hot”... -
Page 13: Speed Adjust Potentiometer
Installation Speed adjust potentiometer Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided (Figure 3). 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. -
Page 14: Manual/Signal Header (Sw501)
Installation Manual/signal header (SW501) Place a jumper on the manual/signal header (SW501) to set the drive for manual (speed adjust potentiometer) input or 0–10 VDC signal input. See Figure 4a and 4b for manual and signal settings. Figure 4. Manual/Signal Switch Set for (a) Manual Input and (b) Signal Input... -
Page 15: Connections
Installation Connections Minarik drives supply motor voltage to terminals A1 and A2 (A1 is positive with respect to A2). It is assumed throughout this manual that the driven motor will rotate clockwise (CW) while looking at the output shaft protruding from the front of the motor. If the opposite is desired, simply reverse the wiring of A1 and A2 with each other. -
Page 16: Operation
Operation Warning Dangerous voltages exist on the drive when it is powered, and up to 30 seconds after power is removed and the motor stops. BE ALERT. High voltages can cause serious or fatal injury. For your safety, use personal protective equipment (PPE) when operating this drive. -
Page 17: Line Starting And Line Stopping
Operation 4. Remove AC line voltage from the drive to coast the motor to a stop. If the motor or drive does not perform as described, disconnect the AC line voltage immediately. Refer to the Troubleshooting section, page 28, for further assistance. Line starting and line stopping Line starting and line stopping (applying and removing AC line voltage) is recommended for infrequent starting and stopping of... -
Page 18: Decelerating To Minimum Speed
Operation Decelerating to minimum speed A switch may be added to the drive’s input to decelerate the motor from set speed to minimum speed. See Figure 6a and 6b for switch connections for both manual and signal input. Close the switch to decelerate the motor from set speed to minimum speed (minimum speed is determined by the MIN SPD trimpot setting). -
Page 19: Dynamic Braking
Operation Dynamic braking Dynamic braking may be used to rapidly stop a motor (see Figure 7a and 7b). For the RUN/BRAKE switch, use a double pole, double throw switch rated for at least the maximum DC armature voltage and maximum (a) Manual Input braking current. -
Page 20: Table 1. Recommended Dynamic Brake Resistor Sizes
Operation Size the dynamic brake resistor according to the motor current rating (see Table 1). The dynamic brake resistance listed in the table is the smallest recommended resistance allowed to prevent possible demagnetization of the motor. The motor stops less rapidly with higher brake resistor values. -
Page 21: Calibration
Calibration Warning Dangerous voltages exist on the drive when it is powered. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots 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. -
Page 22: Minimum Speed (Min Spd)
Calibration MINIMUM SPEED (MIN SPD) The MIN SPD setting determines the motor speed when the speed adjust potentiometer is turned full CCW. It is factory set to zero speed, and can be calibrated with a MANUAL or SIGNAL input. To calibrate, set the MIN SPD trimpot to full CCW. Turn the speed adjust potentiometer full CCW, or set the signal input to 0 VDC. -
Page 23: Current Limit (Curr Limit)
Although Current Limit can be set to 120% of motor nameplate current rating, continuous operation beyond this rating may damage the motor. If you intend to operate beyond this rating, contact your Minarik representative for assistance. The CURR LIMIT setting determines the maximum armature current output of the drive. -
Page 24: Ir Compensation (Ir Comp)
Calibration IR COMPENSATION (IR COMP) The IR COMP setting 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 horsepower motor. -

Page 26: Application Notes
Application Notes Multiple fixed speeds Replace the speed adjust potentiometer with series resistors with a total series resistance of 10K ohms (Figure 9). Add a single pole, multi-position switch with the correct number of positions for the desired number of fixed speeds. Figure 9. -
Page 27: Adjustable Speeds Using Potentiometers In Series
Application Notes 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 10 shows a connection for fixed high and low speed adjust potentiometers. Figure 10. -
Page 28: Independent Adjustable Speeds
Application Notes Independent adjustable speeds Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in parallel, with a total parallel resistance of 10K ohms. Figure 11 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations. -
