I2t monitoring alarm excessive power unit temperature rise

Message value: -
Message class: Power electronics faulted (5)
Drive object: DC_CTRL
Reaction: NONE
Acknowledge: NONE
Cause: The temperature rise of the thyristors is more than 102 % of the maximum permissible value.
Remedy: - Check the ambient temperature and reduce if necessary.
- Check the motor load and reduce if necessary.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY

Ramp-function generator parameter set cannot be selected

Message value: -
Message class: Hardware/software error (1)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: Ramp-function generator parameter sets 2 and 3 were selected simultaneously for more than 0.5 s via binector input
p50637/p50638.
The ramp-function generator parameter set is not changed over. The most recently selected ramp-function generator
parameter set is retained.
Remedy: - Check the selection of ramp-function generator parameter sets 2 and 3 and bar simultaneous selection.
- Select the required ramp-function generator parameter set (p50637, p50638).

Defective tachometer monitoring error

Message value: %1
Message class: Actual position/speed value incorrect or not available (11)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The ratio "Speed actual value/EMF actual value" (r52179/r52287) was less than +10 % for more than approx. 40 ms.
This ratio is then only checked if the EMF actual value is > p50357.
- Cable break affecting tachometer or incremental encoder TTL/HTL
- Tachometer or incremental encoder TTL/HTL cable connected incorrectly
- Incremental encoder TTL/HTL power supply has failed
- Tachometer or incremental encoder TTL/HTL faulty
- Parameters for incremental encoder TTL/HTL set incorrectly (p0400).
- During operation with field reversal, the field polarity is not being reversed by the external hardware
- Polarity for speed actual value set incorrectly (p50743)
- Data for armature circuit set incorrectly (p50110 and p50111)
- If p50083 = 3 (EMF as speed actual value): Interrupted armature circuit (e.g. fuse blown).
- Device operates as slave connected in parallel.
