Prefaceiv Revision June 2010Main Circuit Wiring¾ Install the encoder cables in a separate conduit from the motor power cables to avoidsignal noise. Separate the conduits by 30cm (11.8inches) or more.¾ 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.).¾ As a charge may still remain in the drive with hazardous voltages even after power hasbeen removed, be sure to wait at least 10 minutes after power has been removed beforeperforming any wiring and/or inspection.¾ It is not recommended to frequently power the drive on and off. Do not turn the drive offand on more than once per minute as high charging currents within the internalcapacitors may cause damage.Main Circuit Terminal Wiring¾ Please perform the wiring after the terminal blocks are all removed from the drive.¾ Insert only one wire into one terminal on the terminal block.¾ When inserting wires, please ensure that the conductors are not shorted to adjacentterminals or wires.¾ Ensure to double check the wiring before applying power to the drive.¾ If the wiring is in error, perform the wiring again with proper tools. Never use force toremove the terminals or wires. Otherwise, it may result in malfunction or damage.NOTE 1) In this manual, actual measured values are in metric units.
