Parameters described in this page can be accessed by:

AUTO DC INJECTION

Code Name / Description Adjustment range Factory setting

FUn- [APPLICATION FUNCT.] (continued)

AdC- [AUTO DC INJECTION]

AdC [Auto DC injection]

[Yes] (YES)

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

When [Auto DC injection] (AdC) is set to [Continuous] (Ct), the injection of current is done even if a run

command has not been sent.

Check this action will not endanger personnel or equipment in any way.

Failure to follow these instructions will result in death or serious injury.

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.

YES

Automatic current injection on stopping (at the end of the ramp).

Note: There is an interlock between this function and [Motor fluxing] (FLU) page 83

. If [Motor fluxing] (FLU) is set

to [Continuous] (FCt), [Auto DC injection] (AdC) must be [No] (nO).

Note: [Auto DC injection] (AdC) is set to [No] (nO) when [Motor control type] (Ctt) page 92

is set to

[Sync. mot.] (SYn).

[Auto DC injection] (AdC) is forced to [No] (nO) when [Brake assignment] (bLC) page 179

is not set to [No] (nO).

This parameter gives rise to the injection of current even if a run command has not been sent. It can be accessed with the drive

running.

[No] (nO): No injection

[Yes] (YES): Adjustable injection time

[Continuous] (Ct): Continuous standstill injection

SdC1 [Auto DC inj. level 1]

0 to 1.2 In (2) 0.7 In (2)

(1)

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 standstill DC injection current [Auto DC injection] (AdC) is not [No] (nO).

tdC1 [Auto DC inj. time 1]

0.1 to 30 s 0.5 s

(1)

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.

Standstill injection time. This parameter can be accessed if [Auto DC injection] (AdC) is not set to [No] (nO).

If [Motor control type] (Ctt) page 92

is set to [Sync. mot.](SYn), this time corresponds to the zero speed maintenance time.
