F052
n-Cntr.Input
Control track input (-X103/27, or -X104/27
Compact PLUS) is not high:
- Tachometer line broken
- Tachometer fault
The fault input on the TSY was activated.
Unselect tachometer with control track (P130
select motor encoder)
Check control track connection (-X103/27, or
X104/27 Compact PLUS)
Exchange TSY
F053
Tachometer dn/dt
The permissible change value of the speed
encoder signal P215 dn(act,perm) has been
doubly exceeded.
Check tachometer cables for interruptions.
Check earthing of tachometer shield.
- The shield must be connected both at the
motor and the converter side.
- The encoder cable must not be interrupted.
- The encoder cable must not be laid together
with the power cables.
- Only recommended encoders should be
used.
- In the case of a signal fault, the DT1 board
may have to be used. If necessary, change
P215
- With P806
(observe parameter description) it is possible
during operation to switch over to encoder-free
operation.
F054
Sensor board
initialization fault
A fault has occurred during initialization of the
encoder board.
Fault value r949
1. Board code incorrect
2. TSY not compatible
3. SBP not compatible
7. Board double
20: TSY board double
60: Internal error
F056
SIMOLINK telegram
failure
Communication on the SIMOLINK ring is
disturbed.
- Check the fiber-optic cable ring
- Check whether an SLB in the ring is without
voltage
- Check whether an SLB in the ring is faulty
- Check P741 (SLB TlgOFF)
F057
Brake does not open
The brake has not opened, the output current
of the converter has exceeded the
parameterized current threshold (U840) for
longer than one second (with the rotor locked)
Note:
Only with U800 = 1
Check brake
Check I(max) brake (U840). The set threshold
must be at least 10% above the maximum
possible acceleration current.
F058
Parameter fault
Parameter task
A fault has occurred during the processing of a
parameter task.
No remedy
F059
Parameter fault after
factory setting/init.
A fault has occurred in the initialization phase
during the calculation of a parameter.
The number of the inconsistent parameter is
indicated in fault value r949. Correct this
parameter (ALL indices) and switch voltage off
and on again. Several parameters may be
affected, i.e. repeat process.
