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 Spd ctl tlim min 1 = Speed controller output is being limited by 25.11 Speed control min
torque
2 Spd ctl tlim max 1 = Speed controller output is being limited by 25.12 Speed control
max torque
3 Torq ref max 1 = Torque reference ramp input is being limited by 26.09 Maximum
torque ref , source of 30.25 Maximum torque sel , 30.26 Power
motoring limit or 30.27 Power generating limit . See diagram on page
430 .
4 Torq ref min 1 = Torque reference ramp input is being limited by 26.08 Minimum
torque ref , source of 30.18 Minimum torque sel , 30.26 Power motoring
limit or 30.27 Power generating limit . See diagram on page 430 .
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 or
maximum permanent magnet motor speed limit based on DC voltage
8 Min speed ref lim 1 = Speed reference is being limited by 30.11 Minimum speed or
maximum permanent magnet motor speed limit based on DC voltage
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 Reserved
12 Sw freq ref lim 1 = Requested output frequency cannot be reached because of
switching frequency limitation (because of eg. output filtering or ATEX-
related protections)
13…15 Reserved
