Gain switching input results. Input for switching PI/P
operation and No. 1/No. 2 gains.
•
For No.2 Gain change Funcution, see Protective Adjustments on page 57.
•
Speed zero clamp input results. With COM- open, the
velocity command is considered zero.
• This input can be made disabled using Pr06.
• Default: Contact is set. With COM- open, the velocity
command is considered zero.

This is the input to switch command pulse scaler.
•
With COM- closed, the numerator of the command scaler is changed
from the value stored in Pr46 (Numerator of 1st Command Scaler) to
the value stored in Pr47 (Numerator of 2nd Command Scaler).
<Note>
Don't enter command pulses 10 ms after or before switching.
•
The internal velocity selection 1 (input) is valid. 4 kinds of velocity
settings are available by the combination with CL/INTSPD2 input.
• See control mode setting Pr02 (APP. 16).
