MHT258a (Engl.)5-37
● Brake timing (on origin return, interrupt positioning)
・The brake timing output is held off from when the power supply is applied until any kind of rotation command is given.
When the following control input (ON edge) signals are given, the brake timing output is turned on.
When starting a movement : Brake timing turns on at the ON edge of control input signal.
After the brake releasing time (system para. 83), a rotation starts assuming that the brake has actually
been released.
When terminating the movement : After the amplifier has checked the “deviation zero” (positioning complete), turned off the brake
timing, and the brake operation time (system para. 82) has elapsed, the amplifier turns on P-action
signal. Brake timing output does not turn off if a movement restarts at the ON edge of control input
signal during the brake operation time.
Brake timing (Validated signal at the ON edge)
* If an external brake is used, the motor comes to free-run status at the timing of P-action as shown on the above figure.
