6.8.2 Motor shaft fixing control
: Motor shaft fixing control
• Function
This function is used to prevent the motor from running unexpectedly after the motor is stopped because
it's shaft is not restrained or to preheat the motor.
[Parameter setting]
Title
If the motor shaft fixing control parameter is set at , DC braking continue at half a braking rate of that set
with to retain the motor after it has come to a full stop by DC braking. To discontinue motor shaft axis fixing
control, cancel the assignment of the input terminal function "ST standby command (6)" to an input terminal. Note,
however, that this function doesn't operate after a DC braking command is entered by control input terminal signal.
When assigning the ST function to the S3 terminal.
