F276 Absolute encoder out of allowed window
When turning off the drive controller with an absolute encoder, the actual
feedback position will be stored. When powered up, the absolute position
given by the encoder is compared with the stored position. If the
divergence is greater than the parameterized P-0-0097, Absolute
encoder monitoring window, the error F276 is generated and
transferred to the control unit.
Cause:
1. Turning on for the first time (invalid stored position).
2. While turned off, the axis was moved further than the distance
parameterized in P-0-0097, Absolute encoder monitoring window.
3. Incorrect position initialization.
Remedy for:
1. Press S1 to reset the error and set the absolute position.
2. The axis was moved while turned off and sits outside of its
permissible position. Check to see if the displayed position is correct
in relation to the machine zero point. Then reset the error.
3. Check whether the error is generated again. If yes, the electronics
module is possibly defective and will have to be replaced.
WARNING
An accident may occur by accidental axis movement.
Check absolute position information. The feedback is
defective if the absolute position information is wrong.
The motor should be exchanged and sent to the Rexroth
Indramat Customer Service.
Note: If a customer password is activated and the drive controller is
locked, then error F276 Absolute encoder out of allowed
window cannot be reset. The drive controller must be
unlocked first.
See also the functional description "Absolute encoder monitoring".
F277 Current measurement trim wrong
The current reading in the drive controller is compensated for during
operation. The compensation values are stored in parameters P-0-4000
and P-0-4001. These values are queried to ensure they maintain the
tolerance of +/-10 %. Should the values be greater, then this error is
generated.
Cause:
1. Hardware defective in the drive controller.
Remedy:
1. Replace hardware.
