Hiperface encoder: Unknown encoder [0x007b003c]
Hiperface encoder: Position initialisation error [0x007b003d]
Encoder monitoring: Pulse deviation detected [0x007b003e]
Module ID (decimal) Error ID (decimal)
123: Motor control 60
Response (Lenze setting printed in bold)
 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Encoder is not supported by the controller firmware. • Exchange encoder for known type.
• From software version V4.0: Parameterise the
unknown encoder with the codes C00414 (type code)
and C00415 (number of revolutions).

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
A digital readout of the absolute encoder is only possible
at standstill.
The readout is activated by the following actions:
• Mains switching
• Change of C00420 , C00422 and C00427
• To " Absolute value encoder: Communication error "
• To " Encoder: Open circuit "
Note: This information is always supplied together with
the "I/O error - encoder communication" error message
and is entered in the logbook even if the encoder
monitoring is deactivated ( C00580 ).
Prevent coasting of the machine while the absolute
encoder is read out.

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
• Encoder signal interferences (EMC).
• Encoder cable interrupted.
• Encoder defective.
• Faulty parameter setting of the encoder.
• Check encoder cable, use shorter encoder cable if
required.
• Check encoder.
• Check parameter setting ( C00422 ).
• Possibly switch off monitoring ( C00621 ).
