Block B, C parameter skip

These parameter allows selection of parameters to be displayed.
Unnecessary displays can be reduced with this parameter, allowing easier operation.
All displays are set to skip as the default.
A10-0

ASR response

This parameter is used to calculate the gain of the ASR.
ASR gain :
Kp = ASR response (A10-0) [rad/s] x
ASR integral time constant :
Ti =
Machine constant − 1
A10-1
This is used to calculate the ASR gain. This is valid when the sequence input machine time
constant changeover is OFF (MCH = OFF).

A10-3 ASR drive torque limit
A10-4
ASR regenerative torque limit
A10-5 Emergency stop regenerative torque limit
A11-2 ACR drive torque limit
A11-3 ACR regenerative torque limit
The output current is limited by the overcurrent limit value (B18-0). To generate motor torque
set a value larger than the value given in below expression. .
