F2042 Encoder 2: encoder signals incorrect

Cause
Defective encoder cable or cable shielding
Encoder defective
Faulty mounting of measuring head in the case of
linear measuring systems
Measuring system dirty
Hardware defect on control section of drive
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
The signals of the measuring system (encoder 2) are monitored with
regard to their amplitudes and signal shape. If a signal (sin or cos) leaves
the allowed range or if the signals are disturbed in such a way that a
position error occurs, this error is generated.
Note: As the position is no longer generated correctly when this error
is detected, it is necessary to initialize the encoder again.
Remedy
Check cable to measuring system and replace it, if
necessary
Check measuring system and replace it, if necessary
Check mounting of measuring head and correct it, if
necessary
Replace measuring system
Replace control section or entire drive controller
Note: Only Rexroth service engineers or especially trained users are
allowed to replace the control section. The replacement of the
entire drive controller is described in the Project Planning
Manual for the power section.
Note: When using an incremental encoder with square-wave signals,
monitoring is carried out with regard to an unallowed edge.
With regard to the software the signals of a resolver are
monitored for their level.
