Response (Lenze setting printed in bold) Setting: C00586 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
• HTL encoder cable interrupted.
• HTL encoder is defective.
Note: May also be caused by a very dynamic acceleration
or starting up against a blocked motor shaft (e.g. with a
closed holding brake).
• Check HTL encoder cable.
• Check HTL encoder.
• Check related terminals.
• Switch off monitoring ( C00586 = "0: No reaction")
when the HTL encoder is not used.
Response (Lenze setting printed in bold) Setting: C00598/1 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Open-circuit monitoring for analog input 1 has tripped.
• Only if the analog input has been configured as a cur-
rent loop of 4 ... 20 mA ( C00034/1 = 2).
• Check wiring of the analog input terminals for open
circuit.
• Check minimum current values of the signal sources.
Response (Lenze setting printed in bold) Setting: C01501/1 ( Adjustable response)
 No Reaction  Fault  Trouble  WarningLocked
Cause Remedy
Communication error with communication unit • Eliminate EMC interference.
• Mains switching or restart of the controller, respec-
tively.
• Exchange communication unit/drive unit.
• Please contact Lenze if the problem occurs again.
