Under Voltage Handling
2.7.1
Undervoltage handling
The MAC motor offers the possibility to define the behaviour during and after the mains-
voltage disappear. This situation could for example be during an emergency stop which
causes the mains supply to be cut while the control voltage is still applied to the motor.
3 options exist:
2.7.2
Undervoltage -> Set error bit
Default = Off.
If this option is selected an under voltage will be handled like an error situation and the
corresponding error bit will be set. The motor is stopped using the “error deceleration’
before the motor is switched to passive mode, like any other error situation.
When the main power is re-applied the motor will stay in passive mode and report and
under voltage error. To get the motor back in normal operation the error must be
cleared and a operation mode must be selected.
2.7.3
Undervoltage -> Stop controlled and go to passive
Default = Off
This option makes the motor decelerating according to the normal acceleration param-
eter and go to passive mode when the mains power is removed. When main power is
re-applied the motor stay in passive mode. To get the motor back in normal operation
an operation mode must be selected.
2.7.4
Undervoltage -> Set velocity to 0
Default = Off.
This option simply just set the velocity to 0 causing the motor to decelerate and stay sta-
tionary (except in “torque direct mode”) when mains power is removed. The velocity
setting will stay at 0 also after the main power is re-applied. A velocity value (>0RPM)
must be written into the velocity register to get the motor moving again.

Undervoltage Handling
Use these fields to define the behaviour of the
motor when mains power disappear.
