• You can select whether to enable or disable the internal velocity set-up.
• There are four options of internal velocity commands: Pr53 (1st speed), Pr54 (2nd
speed), Pr55 (3rd speed) and Pr56 (4th speed).
• Block diagrams of the internal and external velocity set-up functions
A INH (CN I/F Pin 33): Internal velocity command select 1
B CL (CN I/F Pin 30): Internal velocity command select 2
• You can easily set-up the internal speed with contact
inputs only.

• Switching between the four options of internal velocity commands uses two contact inputs.Example: 4-speed opera-
tion using the internal velocity commands To run/stop the motor, you need zero speed clamp input(ZEROSPD) and
Servo-ON input(SRV-ON) in addition to CL/INH input.
