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.
