Number / Fault Cause
F026 UCE lower switch (Compact PLUS) / or UCE
has tripped in phase L2
UCE lower switch /
UCE Ph. L2
F027 Fault pulse resistor (Compact PLUS) / or UCE
has tripped in phase L3
Fault pulse resistor /
UCE Ph. L3
F028 The frequency and the amplitude of the DC
link ripple indicate a single-phase power
Supply phase failure.
F029 A fault has occurred in the measured value
sensing system:
Meas. value sensing
The measured variable at which a fault
occurred during offset adjustment is bit-coded
and stored in r949 :
Bit 0: Current phase L1
Bit 1: Current phase L2
Bit 2: DC link voltage
Bit 3: Inverter temperature
Bit 4: Motor temperature
Bit 5: Analog input 1
Bit 6: Analog input 2
Examples:
- (r949 = 1) Offset adjustment in phase L1 not
possible
- (r949 = 2) Offset adjustment in phase L3 not
possible.
- (r949 = 3) Offset adjustment in phases L1
and L3 not possible.
F035 Parameterizable external fault input 1 has
been activated
Ext. Fault 1
F036 Parameterizable external fault input 2 has
been activated
Ext. Fault 2

SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
Check:
- phase L2 for short-circuit or ground fault
(-X2:V2 - including motor)
- that CU is correctly inserted
- that the switch for 'SAFE STOP' (X9/5-6) is
open (only for units with order Nos....-11,
...-21,...-31, ...-61)
Check:
- phase L3 for short-circuit or ground fault
(-X2:W2 - including motor)
- that CU is correctly inserted
- that the switch for 'SAFE STOP' (X9/5-6) is
open (only for units with order Nos....-11,
...-21,...-31, ...-61)
Check the supply voltage.
Causes in phase L1 and L2:
- Fault in measured value sensing system
- Fault in power section (valve cannot block)
- Fault on CU
Causes on all other measured variables:
- Fault on CU (SIMA) -> replace CU
Check:
- whether there is an external fault
- whether the cable to the appropriate digital
input has been interrupted
- P575 Src No ExtFault1
Check:
- whether there is an external fault
- whether the cable to the appropriate digital
input has been interrupted
- P585 Src No ExtFault2
