Bit Name Val. Information
0 TORQ LIM 1 Drive torque is being limited by the motor control (undervoltage
control, overvoltage control, current limitation, load angle
limitation, or pull-out limitation), or by parameter
20.06 MAXIMUM
TORQUE or 20.07 MINIMUM TORQUE . The source of the
limitation is identified by 6.07 TORQ LIM STATUS .
1 SPD CTL TLIM
MIN 1 Speed controller output minimum torque limit is active. The limit is
defined by parameter
28.10 MIN TORQ SP CTRL .
2 SPD CTL TLIM
MAX 1 Speed controller output maximum torque limit is active. The limit
is defined by parameter
28.11 MAX TORQ SP CTRL .
3 TORQ REF MAX 1 Torque reference ( 3.09 TORQ REF1 ) maximum limit is active.
The limit is defined by parameter 32.04 MAXIMUM TORQ REF .
4 TORQ REF MIN 1 Torque reference ( 3.09 TORQ REF1 ) minimum limit is active. The
limit is defined by parameter 32.05 MINIMUM TORQ REF .
5 TLIM MAX
SPEED 1 Torque reference maximum value is limited by the rush control,
because of maximum speed limit
20.01 MAXIMUM SPEED .
6 TLIM MIN
SPEED 1 Torque reference minimum value is limited by the rush control,
because of minimum speed limit
20.02 MINIMUM SPEED .
