Caution
5.8.2 D.C. Braking
The Inverter offers the facility of D.C. braking as a standard. To this end, the Inverter injects D.C. current into two motor
phases, thereby generating braking torque. The kinetic energy of the machine is dissipated as heat in the motor.
This option enables the drive to be braked to a standstill. It does not permit deceleration to a lower
speed. It may be necessary to measure the braking current in the “U” phase.

This is the minimum time that must be elapsed since an AGy Drive is disconnected from the AC Input before an operator
may service parts inside the Drive to avoid electric shock hazard.
CONDITION:
These values consider a turn off for a Drive supplied at 480Vac +10%, without any option, ( the charge
for the switching supply is the regulation card, the keypad and the 24Vdc fans “if mounted”).
The Drive is disabled. This represents the worst case condition.
