ECODRIVE Drive Controller DKC02.1

2-6 Error Diagnostic Messages DOK-ECODRV-SSE-03VRS**-WAR1-EN-P • 12.96

3. The mechanical system between motor shaft and external

encoder is not rigid (e.g. gear play)

4. Defective encoder cable

5. Defect in signal conditioning of external measuring system

6. Maximum input frequency of encoder interface exceeded

7. External encoder not mounted on driven axis

Remedial action:

Ref. 1. Check S-0-0115, Position feedback 2 type parameter and

S-0-0117, Resolution of rotational feedback

Ref. 2. Check S-0-0121, Input revolutions of load gear,

S-0-0122, Output revolutions of load gear, and

S-0-0123, Feed constant

Ref. 3. Increase S-0-0391, Monitoring Window External Feedback

Ref. 4. Replace encoder cable

Ref. 5. Replace axis controller

Ref. 6. Reduce velocity

Ref. 7. Set S-0-0391, Monitoring Window External Feedback to 0 (de-

activate monitoring function)

F237 Excessive Position Command Difference

Cause:

The position command values that arrive via the SERCOS interface are

monitored when the drive works in position control mode. The position

command value monitoring function responds if two consecutive position

command values require the drive to provide a velocity that is equal to or

greater than the value specified in S-0-0091, Bipolar Velocity Limit

Value. While the excessive position command value is stored in

parameter P-0-0010, the last valid position command value is stored

in parameter P-0-0011.

Remedial action:

Compare S-0-0091, Bipolar Velocity Limit Value with the programmed

velocity and adjust if necessary.

F242 External Encoder Failure: Signals too small

Cause:

In the high-resolution evaluation of an external measuring system, the

analog signals of the measuring system are employed for monitoring the

sine and cosine signal.

Remedial action:

• Check the cables to the measuring system

• Check the measuring system
