• Do not loop the ground wire when using more than one drive.
Control Circuit Wiring Precautions
Consider the following precautions for wiring the control circuits.
• Separate control circuit wiring from main circuit wiring and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC (contact output) from wiring
to other control circuit terminals.
• For external control power supply use a UL Listed Class 2 power supply.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating
faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.
Main Circuit Terminals
Control Circuit Terminals
The figure below shows the control circuit terminal arrangement.
There are two DIP switches, S1 and S3, located on the control board.
Terminal Type Function
R/L1, S/L2, T/L3
Main circuit power
supply input
Connects line power to the drive.
Drives with single-phase 200 V input power use terminals R/L1
and S/L2 only (T/L3 is not used).
U/T1, V/T2, W/T3 Drive output Connects to the motor.
B1, B2 Braking resistor For connecting a braking resistor.
+1, +2 DC reactor connection Linked at shipment. Remove the link to install a DC choke.
+1, – DC power supply input For connecting a DC power supply.
(2 terminals)
Ground Terminal
For 200 V class: Ground with 100 or less
For 400 V class: Ground with 10 or less
SW1 Switches analog input A1 between voltage and current input.
SW3
Used to select sourcing (PNP)/sinking (NPN, default) mode for the digital inputs (PNP requires
external 24 Vdc power supply).
S1 S2 S3 S4 S5 SC A1 +V AC AM AC
MCMBMA
Use a straght-edge screwdriver
with a blade width of max 2.5 mm
and a thickness of max 0.6 mm to
release the terminals
