Bit Name Description
0 Torq lim 1 = Drive torque is 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 ramp input is being limited by 26.09 Maximum
torque ref , 30.20 Maximum torque 1 , 30.26 Power motoring limit , or
30.27 Power generating limit . See the diagram on page 496 .
4 Torq ref min 1 = Torque reference ramp input is being limited by 26.08 Minimum
torque ref , 30.19 Minimum torque 1 , 30.26 Power motoring limit , or
30.27 Power generating limit . See the diagram on page 496 .
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
