VMA..KR, VMA..B,C,D,F and DM/DS error displays
Displays flash
alternately.
Action
Error
The drive has switched off.
Normal operation:
Encoder error
Connection error, short circuit or interrup-
tion of encoder cable.
Encoder, encoder evaluation or electronic
rating plate defective.
Special mode (RSU):
Encoder slip
Noise limiter overload
(because of ex-
cessively long, shielded motor cables)
.
For details of the fault, refer to
S-0-0095, cf. page 4–14.
For motor encoder and/or external en-
coder:
D
Check encoder connector
D
Check encoder cable
D
Replace motor
D
Replace module
With RSU:
D
Check if max. 8 modules per VM
D
Noise limiter overload if P-0-0047
[
20 V
Trailing error,
Standstill monitoring
Axis moves without traversing command
D
Check mechanical system
Excessive controller deviation
Drive was not able to follow the setpoint
inputs.
DS modules: Undervoltage in DC link
D
Compare max. setpoint input to speed
limit (S-0-0091)
D
Check lag
D
DS: Check power supply
D
SERCOS interface
:
Observe current limit for braking/accel-
eration (P-0-0061, P-0-0062);
Increase acceleration limit S-0-0138;
In mode “Special operation” adjust the
setpoint input of the NC to the setup
speed P-0-0012.
Position limit exceeded
The setpoint input leads to an axis position
outside the traversing range.
D
Check position limit parameters
S-0-0049 and S-0-0050
D
Check setting of software limit switches
Normal operation:
Maximum speed exceeded (channel 1)
D
The speed limit value S-0-0091 was ex-
ceeded.
Special operating mode (RSU):
Deviation from Safe Standstill
(channel 1)
D
The angle of rotation limit value
P-0-0022 was exceeded.
Special mode with acknowledgement
(RSU):
Deviation from Safe Speed
(channel 1)
D
The speed limit value P-0-0012 was ex-
ceeded.
D
Observe speed limit
D
Observe sequence of operations
D
Check enable signals
D
Check control circuits
D
Clear error by “Reset Diagnostics class
1 error”
.
Check whether the fan on the bot-
tom side of the module has failed.
