ECODRIVE Drive Controller DKC02.1

3-4 Warning Diagnostic Messages DOK-ECODRV-SSE-03VRS**-WAR1-EN-P • 12.96

E259 Command velocity limitation active

In position control and velocity control mode, the effective velocity

command value is limited to the value in parameter S-0-0091, Bipolar

Velocity Limit Value. This warning is output if the resulting velocity

command value reaches this limit.

Cause:

The value of parameter S-0-0091, Bipolar Velocity Limit Value is too

low.

Remedial action:

In normal operation, the parameter S-0-0091, Bipolar Velocity Limit

Value should be set to a value that is 10% higher than the NC working

speed.

E410 Slave not scanned or address 0

Each slave that shall participate in the further phase startup process

must be addressed by the SERCOS master during initialization of the

SERCOS loop in communication phase 1. Each slave that has not been

addressed or for which drive address "0" has been selected issues a

warning E410. Communicating with these slaves at higher

communication phases is not possible. They merely work in repeater

mode.

Cause:

Slave has not been scanned in phase 1, or address "0" has been

selected.

Remedial action:

•

Select the correct slave address

•

Check the SERCOS master configuration

E825 Overvoltage in the Power Stage

Cause:

1. The energy recovered by the mechanical machine system via the

motor has momentarily risen to a level that the bleeder could not

completely convert into heat. Consequently, the DC bus voltage

has exceeded the permissible maximum limit. This has de-

activated the motor torque. The controller is re-activated when

the DC bus voltage falls below the permissible maximum value.

2. DC bus voltage is too high.

Remedial action:

Ref. 1. Reduce the acceleration values and check the drive rating. If

necessary, use an additional bleeder.

Ref. 2 Check the mains power supply.
