to 7.3.4 Speed/Torque Control Switching Function for more details.

Zero-servo Command (Setting: 72)

OFF

Normal operation

ON

D

With this setting, the multi-function input controls the zero-servo function (b9-01 and b9-02).

D

When the zero-servo command is ON, a position control loop is formed and the motor is completely

stopped when the frequency (speed) reference falls below the excitation level set in b2-01. Refer to 7.3.2

OFF

The gain is set according to the values in C5-01, C5-03, and C5-07.

ON

The gain is set to the value in C5-03 (ASR proportional gain 2).

D

With this setting, the multi-function input switches the proportional gain used in speed control (ASR).

The integral time is not changed.

D
