Rockwell Automation SP600 User Manual Version 3.0 - Manual (Page 53)

Wiring Requirements for the Drive 4-5
4.2 Control and Signal Wire Sizes
The terminal block on the SP 600 I/O interface board provides
terminals for 24 V or 115 VAC power for the control inputs,
depending on the I/O card installed in the drive. Refer to 4.3 for
signal and control wiring specifications.
4.3 Recommended Motor Lead Lengths
Important: To reduce line disturbances and noise, motor lead
length should not exceed 300 feet for any non-
Reliance Electric motor or any non-inverter duty
motor.
The length of cable between the drive and motor may be limited for
various applications reasons. The primary reasons are:
• Reflected wave
• Cable charging
!
ATTENTION: Verify the voltage rating of the I/O interface
board before wiring any user devices. Failure to observe this
precaution could result in damage to, or destruction of, the
equipment.
