D Speed Torque Control Change (Setting: 71)
OFF Speed control
ON Torque control
• With this setting, the multi-function input can be used to switch between speed and torque control.
Note Refer to
6-3-5 Speed/Torque Control Switching Function
for more details.
D Zero-servo Command (Setting: 72)
OFF Normal operation
ON Locks position 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).
• 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.
Note Refer to
6-3-3 Zero-servo Function (Position-lock)
for more details.
D ASR 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).
(The integral time is not changed.)
Note Refer
to
5-4-4 Speed Loop (ASR) Structure
for more details on parameters C5-01, C5-03, and
C5-07.
