Run on ref/No Warn- Motor runs at reference speed.
ing
Alarm An alarm activates output.
Alarm on Warning An alarm or warning activates output.
Out of Current Range Motor current is outside range set in parameters 4-50 and 4-51.
Below Current, low Motor current is lower than set in par. 4-50.
Above Current, high Motor current is higher than set in par. 4-51.
Thermal Warning Thermal warning is present when temperature exceeds limit in
motor, frequency converter, brake resistor or thermistor.
Ready, No Thermal Frequency converter is ready for operation and no over-tem-
Warning perature warning is present.
Remote Ready, No Frequency converter is ready for operation in Auto mode, and
Thermal Warning no over-temperature warning is present.
Ready, Voltage OK Frequency converter is ready for operation and mains voltage is
within specified voltage range.
Reverse Motor runs/is ready to run clockwise when logic = 0 and counter
clockwise when logic = 1. Output changes as soon as reversing
signal is applied.
Bus OK Active communication (no time-out) via serial communication
port.
Brake, No Warn Brake is active, and no warnings are present.
Brake Ready/No Fault Brake is ready for operation, and no faults are present.
Brake Fault (IGBT) Protects frequency converter if fault on brake modules is
present. Use relay to cut out main voltage from frequency con-
verter.
Mech. Brake Control Enables control of external mechanical brake, see parameter
group 2-2*.
Control Word Bit 11 Bit 11 in control word controls relay.

Comparator 0 See par. group 13-1*. If comparator 0 is evaluated as TRUE,
output goes high. Otherwise, it is low.
Comparator 1 See par. group 13-1*. If comparator 1 is evaluated as TRUE,
output goes high. Otherwise, it is low.
Comparator 2 See par. group 13-1*. If comparator 2 is evaluated as TRUE,
output goes high. Otherwise, it is low.
