Control Circuit Wiring
(1) Control terminal block designations
The control leads must be routed separately from the power supply and motor leads.
They must not be fed through the same cable conduit.

DFM - DCM Digital frequency meter Digital frequency output (0, +10 V)
TRG - DCM Counter trigger input “Open”→“Close”:(counter value)+1
MO1 - MCM Multi-function PHC output 1 Refer to Pr.45, 46
MO2 - MCM Multi-function PHC output 2 (open collector output)
+10V - ACM Power supply for speed setting +10 V (20 mA max. output current)

0 ∼10 V (Max. output freq.) output
SG+ - SG- Serial communication interface RS-485 serial port
+EV - DCM Auxiliary control power source DC 20V ~ 24V (50mA Max.)
Note: Use twisted-shielded or twisted-pair shielded-lead wires for the control signal. It is
recommended to run signal wiring in a separate steel conduit. The shield wire should only be
connected at the drive.
