Fault messages and list of faults
36 No option
Immediate
switch-off
• Type of option pcb not allowed
• Setpoint source, control source or
operating mode not permitted for this
option pcb
• Incorrect encoder type set for DIP11A.
• Use correct option pcb
• Set correct setpoint source (P100)
• Set correct control signal source (P101)
• Set correct operating mode (P700 or
P701)
• Set the correct encoder type
37
System
watchdog Immediate
switch-off
Fault in system software procedure Contact SEW Service for advice.
38
System
software Immediate
switch-off
System fault Contact SEW Service for advice.
39
Reference
travel Immediate
switch-off
• Reference cam missing or does not switch
• Limit switches not connected correctly
• Reference travel type changed during
reference travel
• Check reference cam
• Check connection of limit switches
• Check reference travel type setting and
the parameters required for it
40
Boot
synchronizatio
n
Immediate
switch-off
Only with DIP11A, DPx11A or DRS11A:
Fault during boot synchronization between
inverter and option.
Fit a new option pcb if this reoccurs.
41
Watchdog
option Immediate
switch-off Fault during communication between system
software and option software.
Contact SEW Service for advice.
42 Lag error
Immediate
switch-off
•
• Incremental encoder connected incorrectly
• Accelerating ramps too short
• P-component of positioning controller too
small
• Speed controller parameters set
incorrectly
• Value of lag error tolerance too small
• Check rotary encoder connection
• Extend ramps
• Set P-component to higher value
• Set speed controller parameters again
• Increase lag error tolerance
• Check encoder, motor and mains phase
wiring
• Check mechanical components can move
freely, possibly blocked up
43
RS-485
timeout
Rapid stop
•
Communication between inverter and PC
interrupted Check connection between inverter and PC.
Contact SEW Service for advice if necessary.
44 Unit utilization
Immediate
switch-off
Unit utilization (IxT value) exceeds 125 %
• Reduce power output
• Extend ramps
• Use a larger inverter if the specified points
are not possible.
45 Initialization
Immediate
switch-off
• No parameters set for EEPROM in power
section or parameters set incorrectly.
• Option pcb not in contact with backplane
bus.
• Restore factory settings. Call SEW
Service for advice if the fault still cannot be
reset.
• Insert the option pcb correctly.
47
System bus
timeout
Rapid stop
•
Fault during communication via system bus. Check system bus connection.
48 Hardware DRS
Immediate
switch-off
Only with DRS11A:
•
Encoder signal for master faulty.
• Hardware required for synchronous
operation is missing.
• Check encoder wiring.
• Fit a new synchronous operation board.
50
Pos. HW limit
switch No
response
Only with DPx11A:
•
Drive has reached position of CW limit
switch.
• Interruption in line between inverter and
CW limit switch.
• Move out of limit switch range using sense
of rotation "CCW".
• Check cabling.
51
Neg. HW limit
switch No
response
Only with DPx11A:
•
Drive has reached position of CCW limit
switch.
• Interruption in line between inverter and
CW limit switch.
• Move out of limit switch range using sense
of rotation "CW".
• Check cabling.
52
Positive
software limit
switch
No
response
Only with DPx11A:
Travel command to a position outside travel
range delimited by CW software limit switch.
• Check travel program and correct if
necessary.
• Correct position of CW software limit
switch.
• Deactivate CW software limit switch by
entering "0" position.
53
Negative
software limit
switch
No
response
Only with DPx11A:
Travel command to a position outside travel
range delimited by CCW software limit switch.
• Check travel program and correct if
necessary.
• Correct position of CCW software limit
switch.
• Deactivate CCW software limit switch by
entering "0" position.
