(3) Origin return [ORG]/Auto start [START]
The brake timing output is held off, from the power is turned on until the rotational 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 release time (system para. 83) has elapsed, a rotation starts assuming that the brake has actually been
released.
When terminating the movement :
After the amplifier has checked the deviation zero (positioning end), turned off the brake timing, and the brake operation
time (system para. 82) has elapsed, the amplifier turns on P-action signal.
The same procedure as when starting a movement above, is performed 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 (free-run) is used, the motor comes to free-run status at the timing of P-action as shown on the above figure.
・During brake operation time, mechanical brake and servo lock (before P-action) are executed simultaneously. For vertically
moving mechanical equipment, there are no time period of motor free-run during stopping.
