WARNING
NO HOLDING TORQUE
• DC injection braking does not provide any holding torque at zero speed.
• DC injection braking does not work when there is a loss of power or when the drive detects a fault.
• Where necessary, use a separate brake to maintain torque levels.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

...
DC injection braking is initiated when the assigned input or bit changes to state 1.
If the input returns to state 0 and the run command is still active, the motor will only restart if [2/3 wire control] (tCC) page 73
is set to [2 wire] (2C) and if [2 wire type] (tCt) is set to [Level] (LEL) or [Fwd priority] (PFO). If not, a new run command
must be sent.
Note: This function cannot be used with certain other functions. Follow the instructions on page 148
.

CAUTION
RISK OF DAMAGE TO THE MOTOR
Check that the motor will withstand this current without overheating.
Failure to follow these instructions can result in equipment damage.
Level of DC injection braking current activated via logic input or selected as stop mode.
This parameter can be accessed if [Type of stop] (Stt) is set to [DC injection] (dCI) or if [DC injection assign.] (dCI)
is not [No] (nO).

CAUTION
RISK OF DAMAGE TO THE MOTOR
• Long periods of DC injection braking can cause overheating and damage the motor.
• Protect the motor by avoiding long periods of DC injection braking.
Failure to follow these instructions can result in equipment damage.
Maximum current injection time [DC inject. level 1] (IdC). After this time, the injection current becomes
[DC inject. level 2] (IdC2).
This parameter can be accessed if [Type of stop] (Stt) is set to [DC injection] (dCI) or if [DC injection assign.] (dCI)
is not set to [No] (nO).
