CAUTION
KEEP ANALOG SPEED REF. (I.E. CONTROL CIRCUIT) WIRING
SEPARATE FROM MAIN CIRCUIT INPUT/OUTPUT WIRING.
CAUTION
TO PREVENT ERRONEOUS OPERATION CAUSED BY NOISE
INTERFERENCE, USE SHEILDED CABLE FOR CONTROL
WIRING, AND LIMIT DISTANCE TO 10M (33 FEET) OR LESS.
IMPORTANT
Because the analog speed reference is converted by 1/16384 resolution, the
voltage source accuracy of the analog speed reference source must be con-
sidered. To ensure speed control accuracy, use a high precision power supply for
the voltage source.
Route wires from the drive and connect to the peripheral device. Refer to "Electrical Installation" in the drive’s
technical manual for further information on use of shielded cable.
