If the param eter
[Auto DC injection]
(AdC) is set to
[Continuous]
(Ct), DC injection is always active, even
if the motor does not run.

Verify that us ing this s etting does not res ult in uns afe conditions.
Failure to follow these instructions will result in death or serious injury.
WARNING
UNINTENDED MOVEMENT
•
Do not us e DC injection to generate holding torque when the m otor is at a stands till.
•
Us e a holding brake to keep the m otor in the stands till pos ition.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Automatic current injection on stopping (at the end of the ramp).
