10.6 Error table
Error code Description Switch-off
response
Cause/solution
Error 01 Overcurrent in output
stage
Output stage
inhibit / locked
Short circuit on inverter output.
→ Check the connection between the inverter output and the motor as
well as the motor winding for short circuits.
Reset error by switching the unit off or via error reset function.
Error 06 Line phase failure Parameterizable Check the supply system cable for phase failure.
Reset error by switching the unit off or via error reset function
Error 07 DC link voltage too high Output stage
inhibit/waiting
• Ramp time too short → Extend ramp time
• Faulty braking resistor connection → Check braking resistor
connection and correct it, if necessary
• Invalid voltage range of the supply input voltage → Check supply
input voltage for permitted voltage range
Reset error by switching the unit off or via error reset function.
Error 08 Speed monitoring error Output stage
inhibit/waiting
Speed monitoring has tripped, load on the drive too high
→ Reduce the load on the drive
→ Extend the n-monitoring delay time
→ Check current and torque limits
→ Deactivate speed monitoring
Reset error by switching the unit off or via error reset function.
Error 10 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 11 Overtemperature of heat
sink or electronics
Emergency
stop/waiting
→ Clean the heat sink
→ Lower the ambient temperature
→ Prevent heat build-up
→ Reduce the load on the drive
Reset error by switching the unit off or via error reset function.
Error 15 Encoder error Output stage
inhibit / locked
• Loose encoder plug connection → check encoder plug connector
on connection board
• Encoder defective → contact SEW Service
Error 16 Incorrect startup Output stage
inhibit / locked
Encoder not calibrated
→ Contact SEW Service
Error 17 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 18 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 25 NV memory error Output stage
inhibit / locked
Err
or while accessing NV memory
Set the delivery status and re-parameterize the unit.
Consult SEW Service if the error re-occurs.
Error 26 External terminal error Parameterizable External error signal read-in at programmable terminal
→ Rectify external error
→ Reset error by switching the unit off or via error reset function.
Error 27 "Limit switch" error Output stage
inhibit / locked
• A limit switch was reached in positioning mode → Check travel
range
• Wire breakage / both limit switches missing or inverted → Check
wiring
Error 29 "Limit switch" error Emergency
stop/waiting
• A limit switch was reached in positioning mode → Check travel
range
• Wire breakage / both limit switches missing or inverted → Check
wiring
Error 30 Emergency stop timeout
error
Output stage
inhibit/waiting
• Emergency stop ramp too short → Extend emergency stop ramp
• Drive overloaded → Check project planning
