94 Configuration
95, 96 Motor supply voltage is too low.
97, 98 Motor supply voltage is too high.

110,113,127 Configuration
116, 117 Active power consumption of the
motor is too low.
120, 121 Active power consumption of the
motor is too low
122 No voltage on one or more phases.
Possible causes are a blown fuse
or a wire break.
123 There is a high imbalance on
supply side e.g. because of
unsymmetrical load of the three
phases.
124 The voltage is out of the specified
voltage range
125 The phases were wired in incorrect
order.
Possible Cause / Suggested Action
Check between UMC and motor
Check wiring between UMC and motor
The IO module does not respond during start-up of UMC.
Check wiring between UMC and module
Check supply of module
Check status LEDs of the module
Check wiring, short circuit at analogue output
Check Wiring
A voltage module not supporting single phase mode was
configured for single phase mode. Use a voltage module with
production index A5 or later.
Check supply side: E.g. circuit breaker, fuses, wiring and the
feeding.
Check supply side: E.g. circuit breaker, fuses, wiring and the
feeding.
Check wire between AM1 and signal source
Check wire between AM1 and temerature sensor
Check that the configured sensor type is correct
Check that the correct sensor type is connected
Check that the delivered sensor signal in range.
Either the motor is idle (not loaded) or the motor load is not
connected because of a broken belt or a dry running pump etc.
Check load side
Either the motor is idle (not loaded) or the motor load is not
connected because of a broken belt or a dry running pump etc.
Check load side
Check fuses
Check wiring on supply side.
Check supply side especially the fuses and supply line.
Check supply side. See 95 – 98.
