5.2.3 DGinjection brake
If you want to brake the drive fast, but do not want to use a brake
chopper, you tan activate the DC-injection brake via the suitable
input. Please note that the braking time may vary each time.
Before you tan use the DGinjection brake, set the brake voltage
under C036. The brake voltage also determines the brake current
and therefore the brake torque. If the current limitation is activated
by the brake current, reduce the brake voltage.
To limit the time of the DC-injection brake, you tan program a
holding time under C107. After the holding time has elapsed, the
controller switches the output voltage to Zero. With a holding time
of 999s the braking time is unlimited.
Extended Operation of the IX-injection brake may Cause the motor
to overheat!

With ,terminal control CO48 serves as display whether the DC-
injection brake is active or not.
With control via the keypad or the LECOM interfaces the DC-
injection brake is (de-)activated via C048.
