DOK-ECODR3-SGP-03VRS**-WA01-EN-P
Removing the Battery
• Unscrew torx screws with size 10 screwdriver.
• Pull out the resolver feedback (RSF) lid by hand.
• Pull off the battery connector.
• Loosen battery clamp and remove the battery.
• Place the prepared battery in the housing and screw on the clamp.
Attention! Do not kink or clamp the battery cable.
• Attach the connector of the battery.
• Close the resolver feedback lid, screw in 4 torx screws and tighten to
1.8 Nm with the torque wrench.
Note: If a customer password was activated and the drive controller
locked, the error F2486 Low battery voltage cannot be
cleared. The drive controller first has to be unlocked.
F249 Master drive encoder failure: signal too small
The signals of the master encoder are monitored. If its signal amplitude
falls below a minimum threshold value, then this error message appears.
The drive performs the best possible deceleration, as selected in the
parameter P-0-0119.
Criteria for correct encoder signals:
1. The pointer addition of the sine and cosine signals
must give at least 1 V.
2. The maximum pointer sum of the sine and cosine signals may not
exceed 11.8 V.
Cause:
The analog signals of the measurement system at the master axis do not
have the correct amplitude.
Remedy:
1. Check the encoder cable.
2. Check the encoder.
F250 Overflow of target position preset memory
Cause:
If the attempt is made in mode "Running the positioning command value"
to set a new positioning command value while toggling parameter
S-0-0346, Positioning command latch even though the previous
positioning command value (k+1) has not yet been assumed (because
the previous positioning command value (k) has not yet been run to), then
error F250 Overflow of target position preset memory was generated.
Remedy:
• Wait until the position is run to.
• Use a different positioning mode (e.g., immediate acceptance).
