Fuji Electric RYS...S3-VVS Series - Operation at Stopping; Servo Lock; External Brake

6-2 MHT258a (Engl.)
6.1.2 Operation at stopping
The status when the motor is stopping can be selected.
System parameter 81
Para. Name Setting range Initial value Change
81 Operation at stopping 0 : Speed zero
1 : Servo lock
2 : External brake (P-action)
3 : External brake (free-run)
0 Power
A selected operation at stopping affects to any of speed control, position control and torque control.

1) Speed zero
The motor is stopping without holding the corrent position by “servo lock” assuming that the speed command is zero, If the motor is rotated
by the load machine system, a counter force is activated in the opposite direction to the driven direction (as the speed is not zero.)
In speed control, if “servo lock” is selected as the operation at stopping, the motor can be stopped retaining the current position. “Servo lock”
should be done at the speed lower than “speed zero width” set by basic para. 52.
Set the “operation at stopping” at “zero-speed” in order to generate an analog speed command voltage with the host controller and to obtain
feedback signal via the freq. dividing output from amplifier.
2) Servo lock
The motor can be stopped retaining the current position (current position of motor’s encoder).
3) External brake (P-action)
The motor can be stopped by the motor’s brake, by using the “brake timing” outputted from amplifier. The motor output shaft is mechanically
locked and the control system gain on the amplifier side is lowered.
4) External brake (free-run)
The motor can be stopped by the motor’s brake, by using the “brake timing” outputted from amplifier. Noise or vibration will not be generated
because the no motor control is made.
See 5.7.1 for the use of external brake.
