ECODRIVE Drive Controller DKC02.1

DOK-ECODRV-SSE-03VRS**-WAR1-EN-P • 12.96 Error Diagnostic Messages 2-13

F822 Motor Encoder Failure: Signals too Small

The amplitudes of the sine and cosine signals from the motor encoder

are monitored.

Note: The error cannot be cleared in communication phase 4.

Transition to communication phase 2 is necessary before the

error can be cleared.

Remedial action:

•

Check the cables .

•

The signal cables must be laid separately from the motor power

cables. The screen must be connected at the drive controller (see

Configuration Instructions of the drive controller).

•

Check the measuring system. Replace it if necessary.

F860 Overcurrent: Short in Power Stage

The current in the power transistor bridge has exceeded twice the value

of the device peak current. The torque of the drive is released at once,

and an optional blocking brake is applied immediately.

Cause:

1. Short-circuit in the motor cable

2. Defect in the drive controller’s power stage

Remedial action:

Ref. 1. Check the motor cable for a short-circuit.

Ref. 2. Replace the drive controller

F870 + 24 Volt Error

The drive controller has detected an error in the +24-V supply.

Note: The error cannot be cleared. The unit must be switched off.

Cause:

1. Short-circuit in the emergency stop circuit

2. 24-V supply is below the minimum value

Remedial action:

Ref. 1. Check the emergency stop circuit for short-circuit condition

Ref. 2. Check the power supply unit. Replace it if necessary.
