Preface
Main Circuit Wiring
Install the encoder cables in a separate conduit from the motor power cables to avoid
signal noise. Separate the conduits by 30cm (11.8inches) above.
Use multi-stranded twisted-pair wires or multi-core shielded-pair wires for signal, encoder
(PG) feedback cables. The maximum length of command input cable is 3m (9.84ft.) and
the maximum length of encoder (PG) feedback cables is 20m (65.62ft.).
As a charge may still remain in the drive with hazardous voltages even after power has
been removed, be sure to wait at least 10 minutes after power has been removed before
performing any wiring and/or inspection.
It is not recommended to frequently power the drive on and off. Do not turn the drive off
and on more than once per minute as high charging currents within the internal
capacitors may cause damage.
Main Circuit Terminal Wiring
Please perform the wiring after the terminal blocks are all removed from the drive.
Insert only one wire into one terminal on the terminal block.
When inserting wires, please ensure that the conductors are not shorted to adjacent
terminals or wires.
Ensure to double check the wiring before applying power to the drive.
