In the case of absolute encoder evaluation, the plausibility of the initialized
absolute position is checked during position initialization. If the controller
detects that the position data reference of the encoder cannot be
established any more due to changes of the mechanical system
parameters or due to replacement of encoder or device, the actual
position value status (
S-0-0403, Position feedback value status
) goes
to "relative" and the error F2174 is generated.
Cause
Remedy
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)
Clear error and reestablish position data reference
Switching on without reference
(after replacing motor or motor encoder)
Clear error and establish position data reference
Motor encoder defective
Replace motor or motor encoder, clear error and
establish position data reference
Parameters of mechanical system changed (gear,
feed constant, ...)
Clear error and establish position data reference
Amplifier replaced without parameter update
Clear error and establish position data reference
Switching on without reference after replacement of
device with loaded axis-specific parameter values
(according to list from
S-0-0192, IDN-list of backup
operation data
)
Clear error and establish position data reference
- or -
Clear error, then load parameter values of
P-0-0195,
IDN list of retain data (replacement of devices)
, if it
was possible to save them immediately before device
was replaced. Check reestablished position data
reference for correctness
