F2074 Actual Pos. Value 1 Outside Absolute Encoder Window - Bosch Rexroth IndraDrive Troubleshooting Manual

Error Messages

F2074 Actual pos. value 1 outside absolute encoder window

Cause
While turned off, axis was moved further than
distance contained in P-0-0095, Absolute encoder
monitoring window for motor encoder
Value entered in P-0-0095, Absolute encoder
monitoring window for motor encoder is too low
for existing encoder resolution so that normal
encoder jitter will already cause monitor to be
triggered
Switching on without reference
(in the case of initial commissioning or caused, for
example, by changing parameters that characterize
mechanical system or influence position evaluation)
Switching on without reference
(after replacing motor or motor encoder)
Amplifier replaced without parameter update
Parameters of mechanical system changed (gear,
feed constant, ...)
Motor encoder defective

Supported by Firmware Variant:
When turning off a drive with an encoder that can be evaluated in
absolute form, the current actual position will be stored in the drive. When
switching the drive on again the current position is compared with the
position stored when the drive was switched off the last time. If the
deviation is greater than the value in P-0-0095, Absolute encoder
monitoring window for motor encoder the F2074 error message is
generated.
Note: The monitoring function can be switched off by P-0-0095,
Absolute encoder
encoder = "0".
Remedy
Make sure displayed position is correct in relation to
machine zero point Then clear error and, if necessary,
reestablish position data reference
Check parameterization of P-0-0095, Absolute encoder
monitoring window for motor encoder and increase
monitoring window
Clear error and establish position data reference
Clear error and establish position data reference
Clear error and establish position data reference
Clear error and establish position data reference
Replace motor or motor encoder
Danger of accident by unintended axis motion!
⇒ Check position data reference. The encoder is
defective if the position data reference is incorrect!
Replace the motor and send it to the manufacturer's
WARNING
service department for inspection.
