Fault messages and list of faults
7.1
DRS11B synchronous operation board option
The following fault messages can occur specifically in synchronous operation. A dot in
the "P" column indicates that the response is programmable (P83_ Fault response). The
factory set fault response appears in the "Response" column.

14
Encoder
Immediate
switch-off
•
Encoder cable or shield not con-
nected correctly
•
Short circuit/encoder cable has bro-
ken wire
•
Encoder defective
Check encoder cable and shield for correct connection,
short circuit and broken wire
36
Option miss-
ing
Immediate
switch-off
•
Type of option card not allowed
•
Setpoint source, control signal source
or operating mode not permitted for
this option card
•
Incorrect encoder type set for DIP11B
•
Use correct option card
•
Set correct setpoint source (P100)
•
Set correct control signal source (P101)
•
Set correct operating mode (P700 or P701)
•
Set the correct encoder type
40
Boot synchro-
nization
Immediate
switch-off
Error during boot synchronization
between inverter and option.
Install a new option card if this fault reoccurs.
41
Watchdog
option
IPOS watch-
dog
Immediate
switch-off
•
Error in communication between sys-
tem software and option software
•
Watchdog in the IPOS program
•
An application module without the
application version has been loaded
in a MOVIDRIVE
®
B unit
•
The wrong technology function has
been set if an application module is
used
•
Contact SEW Service.
•
Check IPOS program
•
Check whether the unit has been activated for the
application version (P079)
•
Check the selected technology function (P078)
42
Setpoint devi-
ation
Immediate
switch-off
•
•
Encoder connected incorrectly
•
Acceleration ramps too short
•
P component of positioning controller
too small
•
Incorrectly set speed controller
parameters
•
Value of lag fault tolerance too small
•
Check encoder connection
•
Extend ramps
•
Set P component to higher value
•
Reset speed controller parameters
•
Increase lag fault tolerance
•
Check encoder wiring, motor and mains phase
wiring.
•
Check mechanical components of system can
move freely, possibly blocked up
48
Hardware
DRS
Immediate
switch-off
•
Encoder signal from master/synchro-
nous encoder faulty
•
Hardware required for synchronous
operation is faulty
•
Number of pulses incorrect
•
Check encoder signals of master/synchronous
encoder
•
Check encoder wiring
•
Install a new synchronous operation board
•
