Zero-Servo Command (Setting: 72); Speed Control (Asr) Proportional Gain Switch (Setting: 77) - YASKAWA VARISPEED-616G5 Instruction Manual

With this setting, the multi-function input can be used to switch between speed and torque control. Re-
D
fer to 7.3.4 Speed/Torque Control Switching Function for more details.

Zero-servo Command (Setting: 72)

OFF Normal operation
ON Zero-servo when the frequency (speed) reference falls below the zero-speed level in b2-01.
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
D
stopped when the frequency (speed) reference falls below the excitation level set in b2-01. Refer to
7.3.2 Zero-servo Function for more details.

Speed Control (ASR) Proportional Gain Switch (Setting: 77)

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).
With this setting, the multi-function input switches the proportional gain used in speed control (ASR).
D
The integral time is not changed.
Refer to 6.4.4 Speed Control (ASR) Structure for more details on constants C5-01, C5-03, and C5-07.
