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
592.
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 592.
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 Load angle lim (With permanent magnet motors and synchronous reluctance motors,
and externally-excited synchronous motors in steady state)
1 = Maximum load angle is being limited, ie. the motor cannot produce
any more torque
(With externally-excited synchronous motors in dynamic situations)
1 = Torque is being limited
14…15 Reserved
