Number / Fault Cause
F051 Digital tachometer or analog tachometer
sensing are faulty
Speed encoder
F052 Control track input (-X103/27, or -X104/27
Compact PLUS) is not high:
n-Cntr.Input - Tachometer line broken
- Tachometer fault
The fault input on the TSY was activated.
F053 The permissible change value of the speed
encoder signal P215 dn(act,perm) has been
Tachometer dn/dt doubly exceeded.
F054 A fault has occurred during initialization of the
encoder board.
Sensor board

F056 Communication on the SIMOLINK ring is
disturbed.

SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
Check the parameters:
- P130 Src SpdActV
- P151 Pulse #
- P138 AnalogTachScale
- P109 Motor #PolePairs
The product of P109 and P138 must be
smaller than 19200. Check or replace
tachometer. Check connection to tachometer.
- Replace CU (-A10), or replace the unit
(Compact PLUS type)
Unselect tachometer with control track (P130
select motor encoder)
Check control track connection (-X103/27, or
X104/27 Compact PLUS)
Exchange TSY
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.
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
- 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)
