Description
You can select how to stop the motor.
(FREE)
Power supply to the motor is cut off and the motor is stopped
naturally when stop command is input (free-run stop). It takes
longer for the motor to completely stop when load inertia is big.
(DECEL)
When stop command is input, the motor reduces its speed
according to preset deceleration time, Electric-brake is performed
by Zero-speed control, and then power is cut off to the motor after
" 17 Free-run waiting time

When " 16 Stop mode selection" is set to
deceleration stop, servo lock time (Zero-speed control) after
deceleration can be adjusted.
(Free-run state is set after that.)
Enables setting of proportional gain of velocity amplifier. When
this value is made greater, gain is increased, which improves
responsiveness of the motor. When this value is made too large,
operation is vibratory.
In order to smoothly rotate at low speed, it may be necessary to
adjust the parameter " 1A speed loop proportional gain" larger in
the actual load condition of the actual machine.
If you are using it even at high speed operation, be careful
as vibration increases at high speed operation if the gain is
increased.
Setting range: 0 to 10000, Setting resolution: 1
Enables setting of integration gain of velocity amplifier. When this
value is made greater, gain is increased, which improves rigidity
of the motor (strength of servo lock). When this value is made too
large, overshooting becomes greater, and the motor is vibratory.
