AC voltage supply
too high
Reaction 5: Switch-off of the
current immediately (without
ramp), application of the
brake
Reduce motor utilization (Effective cycle). Current ripple may lead to
motor heating due to a switching frequency set too low (increase
switching frequency).
If the motor is to be operated without temperature monitoring, you
can deactivate the monitoring in the motor manager.
Is the motor temperature sensor (correctly) connected and
configured (threshold value/type in the MotorManager)? Maybe
there is a line breakage or a short circuit on GND with PTC sensors
or a short circuit on 5V with NTC sensors.
Please note that only the KTY84-130 sensor will deliver the correct
temperature value, this does however not influence the
temperature monitoring (only the resistance value is relevant).
NTC sensors are supported as from R09-10!

C3 PSUP: Voltage in
DC bus too low
Reaction 1: Downramp actual
speed; remain in position
control state.
Provide for better cooling or reduce power consumption.
3222 12834
DC link voltage too
low Reaction 2: Downramp /
apply brake / de-energize..
Reduce usage of the braking resistor by longer regenerative times.
Check air supply for cooling the braking resistor. If none of the
described measures is successful or can be taken, a resistor with a
higher nominal power must be used. Note: If no braking resistor or
a braking resistor without temperature switch is used, a wire jumper
must be inserted between T1R and T2R on connector X40.
