Error table
Service
Error 31 TF trip Parameterizable Thermal overload of the motor or short circuit/wire breakage of the
temperature sensor.
→ Lower the ambient temperature
→ Prevent heat build-up
→ Reduce the load on the drive
Leave the motor to cool for at least one minute before you reset the
error by switching off the unit or via error reset function.
Consult SEW Service if the error recurs.
Error 32 IPOS error Output stage
inhibit / locked
Faulty IPOS program (e.g. invalid command)
→ Correct program
Reset error by switching the unit off or via error reset function.
Error 37 CPU error Output stage
inhibit / locked
Reset error by switching the unit off or via error reset function.
Consult SEW Service if the error recurs.
Error 39 "Reference travel" error Output stage
inhibit / locked
The reference cam is missing or does not switch
→ Check reference cam
Limit switches are connected incorrectly
→ Check limit switch connection
Reference travel type was changed during reference travel
→ Check reference travel type setting and required parameters.
Error 40 Boot synchronization error Output stage
inhibit / locked
Command PCB defective or connection to command PCB interrupted.
→ Contact SEW Service
Error 41 Watchdog option error Output stage
inhibit / locked
Command PCB defective or connection to command PCB interrupted.
→ Contact SEW Service
Option defective or connection to option interrupted.
→ Check whether an option is installed
→ Replace the option
Error 42 Lag error positioning Output stage
inhibit/waiting
• Emergency stop ramp too short → Extend emergency stop ramp
• P-component of positioning controller too small → Increase P-
component
• Value of lag error tolerance too small
→ Increase lag error tolerance
→ Check whether mechanical components can move freely
Error 43 Timeout – manual mode
via any interface
Parameterizable • Connection between unit and PC interrupted → Check and re-
establish connection.
Error 44 Ixt utilization / UL monitor-
ing
Output stage
inhibit/waiting
Output stage overload
→ Reduce the load on the drive
Reset error by switching the unit off or via error reset function.
Error 45 Initialization error
Motor-inverter assignment
incorrect
Output stage
inhibit / locked
• Hardware defective → Contact SEW Service.
•
Incorrect motor/inverter assignment → Replace electronics.
Error 46 Timeout – internal SBus
connection between
command PCB and power
section
Emergency
stop/waiting
• Contact SEW Service.
Error 47 Communication interrupted
during cyclical data
exchange
Parameterizable Power section error
• No SBus connection between DRC inverter and controller. Check
and establish connection, especially terminating resistor.
• EMC influence Check shielding of data lines and improve, if
necessary.
• Protocol period between the individual telegrams is longer than the
set time (timeout time). Shorten telegram cycle.
Command PCB error
• Connection to AS-Interface master interrupted → Check and re-
establish connection.
• Connection between AS-Interface option and command PCB
interrupted → Contact SEW Service.
