ATTENTION: If a hazard of injury due to movement of equipment or material exists, an auxiliary mechanical braking device must be used. This feature should
not be used with synchronous motors. Motors may be demagnetized during braking.
A436 [DC Brk Time@Strt] Related Parameter(s): P045, A435
Sets the length of time that DC brake current is “injected” into the motor after a valid start command is received.
