Error table
Service
Fault 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.
Fault 40 Boot synchronization error Output stage
inhibit / locked Command PCB defective or connection to command PCB interrupted.
→ Contact SEW Service
Fault 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
Fault 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-com-
ponent
• Value of lag error tolerance too small
→ Increase lag error tolerance
→ Check whether mechanical components can move freely
Fault 43 Timeout – manual opera-
tion via any interface Parameterizable • Connection between unit and PC interrupted → Check and re-
establish connection.
Fault 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.
Fault 45 Initialization error
Motor-inverter assignment
incorrect Output stage
inhibit / locked • Hardware defective → Contact SEW Service.
• Incorrect motor/inverter assignment → Replace electronics.
Fault 46 Timeout – internal SBus
connection between com-
mand PCB and power sec-
tion Emergency
stop/waiting • Contact SEW Service.
Fault 47 Communication interrupted
during cyclical data
exchange. Parameterizable Power section error
• No SBus connection between MOVIGEAR
®
inverter and controller.
Check and establish connection, especially terminating resistor.
• EMC influence Check shielding of data lines and improve, if neces-
sary.
• 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 inter-
rupted
→ Contact SEW Service.
Fault 50 Internal voltage supply too
low Output stage
inhibit / locked • Hardware defective → Contact SEW Service.
Fault 52 Machine control error Output stage
inhibit / locked • Operation without encoder a speed that is too low → Increase
speed
• Load too high in controlled operation → Reduce load on the drive
Reset error by switching the unit off or via error reset function.
Consult SEW Service if the error recurs.
Fault 53 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.
Fault 77 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.
Fault 89 Only in conjunction with
DRC electronic motor:
Brake overtemperature
Output stage
inhibit / locked Brake coil not sufficient to dissipate the regenerative energy.
→ Use braking resistor
Wrong size of braking resistor selected.
→ Use larger braking resistor
