Bit Name Description
0 Torq lim 1 = Drive torque is being limited by the motor control (undervoltage
control, current control, load angle control or pull-out control), or by the
torque limits defined by parameters.
1…2 Reserved
3 Torq ref max 1 = Torque reference is being limited by 26.09 Maximum torque ref or
30.20 Maximum torque 1
4 Torq ref min 1 = Torque reference is being limited by 26.08 Minimum torque ref or
30.19 Minimum torque 1
5 Tlim max speed 1 = Torque reference is being limited by the rush control because of
maximum speed limit (30.12 Maximum speed)
6 Tlim min speed 1 = Torque reference is being limited by the rush control because of
minimum speed limit (30.11 Minimum speed)
7 Max speed ref lim 1 = Speed reference is being limited by 30.12 Maximum speed
8 Min speed ref lim 1 = Speed reference is being limited by 30.11 Minimum speed
9 Max freq ref lim 1 = Frequency reference is being limited by 30.14 Maximum frequency
10 Min freq ref lim 1 = Frequency reference is being limited by 30.13 Minimum frequency
11…15 Reserved
