The normal waveforms for brake activation are as follows:
Figure 13-5: Normal Brake Activation Timing
At the brake activation times (BP[2] milliseconds to disengage and BP[1] milliseconds to
engage), the motor is controlled to a complete stop.
If MO=0 is set automatically by an exception, the brake is activated immediately,
without any delay.
13.7 When the Motor Fails to Start
The main reasons for failure when starting a motor are:
ƒ
The physical conditions are not right.
ƒ The database is not consistent (refer to section 13.9.2 )
The following physical conditions are checked before voltage is applied to the motor:
ƒ
Power supply under-voltage
ƒ Power supply over-voltage
ƒ Drive temperature too high
ƒ Motor not connected to servo drive
ƒ An active limit switch is programmed to shut down the servo drive
