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).
Speed Adjust Potentiometer
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 5 on page 16.
Analog Input Signal
Instead of using a speed adjust potentiometer, 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 settings and location.
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.
Inhibit Switch
See page 23 for a detailed explanation of the Inhibit switch.
