Follow sound maintenance procedures. It is possible for a drive to run at full speed as a result of a component failure. Minarik strongly recommends the installation of a master switch in the main power input to stop the drive in an emergency.

Installation Mounting Warning Do not install, rewire, or remove this control with input power applied. Doing so may cause fire or serious injury. Make sure you have read and understood the Safety Warnings before attempting installation. The chassis must be earth grounded. Use a star washer beneath the head of at least one of the mounting screws to penetrate the anodized chassis surface and to reach bare metal.
Installation Wiring Warning Do not install, remove, or rewire this equipment with power applied. Failure to heed this warning may result in fire, explo- sion, or serious injury. This drive is isolated from earth ground. 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.
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 of logic level leads is not practical, the user should twist all logic leads with themselves to minimize induced noise.
Installation Line fuses Protect all Minarik drives with AC line fuses. Use fast acting fuses rated for 250 volts, and approximately 150%–200% of the maximum armature current. Line fusing for PCM20000 series drives Minarik drives require an external fuse for protection. Use fast acting fuses rated for 250 VAC or higher, and approximately 150% of the maximum armature current.
Installation Speed adjust potentiometer (Model PCM23001A only) Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the drive. Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided (Figure 3).
Failure to heed this directive may result in fire or serious injury. Minarik strongly recommends the installation of a master power switch in the voltage input line, as shown in Figure 4, page 12. The switch contacts should be rated at a minimum of 200% of motor nameplate current and 250 volts.
Refer to the line fuse chart on page 7 for fuse ratings. Motor connections Minarik drives supply motor 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.

Installation Current and voltage follower The PCM23001A series drives can be configured to follow a grounded (non-isolated) voltage or current signal. To configure the drive to follow a voltage signal, connect the signal leads to the SIGNAL INPUT POS and SIGNAL INPUT NEG terminals, observing proper polarity (see Figure 5).

Failure to heed this directive may result in fire or serious injury. Minarik strongly recommends the installation of a master power switch in the voltage input line, as shown in Figure 7 (page 18). The switch contacts should be rated at a minimum of 200% of motor nameplate current and 250 volts.
Installation Motor connections Minarik drives supply motor 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 this is opposite of the desired rotation, simply reverse the wiring of A1 and A2 with each other.

Operation Warning Dangerous voltages exist on the drive when it is powered. BE ALERT. High voltages can cause serious or fatal injury. Before applying power 1. Verify that no conductive material is present on the printed circuit board. 2. Verify that the AC supply is properly balanced. 3.
Operation Operating Modes PCM23001A operating modes The PCM23001A can operate in one of three modes,determined by shorting selected pins on mode-select header block SO501. An 18-inch harness and mating plug assembly (Minarik p/n 201-0038) is shipped as part of the PCM23001control. Refer to Figure 8 (page 21) for operating mode connections.
Operation PCM23401A/PCM23411A Operating Modes The mode selector switch on the PCM23401A drive, mounted on its cover, provides the option of operating in either MANUAL or SIGNAL mode (see Figure 2, page 3). SIGNAL mode includes the ratio feature described on page 20. Manual/Signal With Ratio Output Mode Selector Connect a switch or relay as shown in Figure 9a (page 23) to select manual or signal with ratio output modes.

Operation Voltage Select Switches Warning Change switch settings only when the drive is disconnected from the AC line voltage. Make sure all switches are set to their correct position before applying power. SCR501 D507 D508 SCR502 MOV501 MOV502 C516 T501 115 230 SW501 LINE VOLTAGE...
Operation Line Voltage (SW501) Prior to applying AC power, ensure that voltage select switches SW501 is set to 115 for 115 VAC line voltage, and 230 for 230 VAC line voltage. Motor Armature Voltage (SW502) Set motor armature voltage switch SW502 to 90 for 90 VDC motor armatures, and 180 for 180 VDC motor armatures.
BE ALERT. High voltages can cause serious or fatal injury. PCM23001A Series drives have six user adjustable trimpots: SIG MAX, SIG MIN, MAX SPD, MIN SPD, IR COMP and TORQUE. Recalibrate the trimpots if a lower current motor is used (lower than the rated maximum of the drive).
Calibration MIN SPD (Minimum Speed) NOTE: Check the MIN and MAX trimpot setting after recalibrating to verify that the motor runs at the desired minimum speed. The MIN trimpot setting determines the motor speed when the speed adjust potentiometer is turned full CCW. It is operational only in MANUAL mode and is factory set to zero speed.
Calibration SIG MIN (Signal Minimum) NOTE: SIG MIN is operative only when the control is in SIGNAL or SIGNAL WITH RATIO OUTPUT mode. The SIG MIN trimpot establishes the motor speed obtained in response to the minimum input signal. To calibrate the SIG MIN pot, apply the minimum signal. Adjust the SIG MIN trimpot until the motor runs at the desired speed or is just at the threshold of rotation.
If you intend to operate beyond the rating, contact your Minarik representative for assistance. The TORQUE trimpot setting determines the maximum torque for accelerating and driving the motor. Use the following procedure to calibrate the TORQUE setting: 1.
Calibration IR COMP (IR Compensation) The IR COMP trimpot setting determines the degree to which motor speed is held constant as the motor load changes. It is factory set for optimum motor regulation. To calibrate IR COMP (exact calibration): 1. Turn the IR COMP trimpot full CCW. 2.
5. Verify that there are no short circuits or grounded connections. 6. Check that the drive’s rated armature outputs are consistent with the motor ratings. For additional assistance, contact your local Minarik distributor, or the factory direct: 1-800-MINARIK (646-2745) or Fax: 1-800-394-6334...

The PCM20000 series has been tested to the following test specifications: EN55011:1991 (emissions), and EN50082-1:1992 (immunity) Compliance allows Minarik’s PCM20000 series to bear the CE mark. The end user, as described herein, falls into one of two categories: 1. The Consumer will deploy a stand-alone unit as an integral, yet external, portion of the machine he/she is operating.
In addition to EMI/RFI safeguards inherent in the PCM20000 series’ design, external filtering is required. Minarik requires the Corcom® filters listed in Table 5. If the exact filter is not available, the specifications are as follows: L = (1.73 + 0.03) milliHenries.
CE Compliance If the end-user is not using a CE-approved motor, a second filter on the output, Minarik’s CEXXMM, must be used. XX = rated current of the filter. The CE20MM is a Real-Pole Balanced-Pi 3-pole filter. If the exact filter is not available, the specifications are as follows: L &...

CE Compliance The OEM has this liberty because CE is a machinery directive. Whether or not every component in the OEM’s machinery meets CE, the OEM must still submit his machine for CE approval. Thus, no component must necessarily meet CE within the machine, as long as the OEM takes the necessary steps to guarantee the machine does meet CE.
