Selection No.
- / uint16 Displays the torque controller limitation status word.
This parameter is read-only.
*Only one out of bits 0…3, and one out of bits 9…13
can be on simultaneously. The bit typically indicates
the limit that is exceeded first. Torque limit status 30.2
*1 = Intermediate DC circuit undervoltage Undervoltage b0
*1 = Intermediate DC circuit overvoltage Overvoltage b1
*1 = Torque is being limited by 30.26 Power motoring
limit , 30.27 Power generating limit or the source of
30.18 Minimum torque sel . See diagram on page 656 .
Minimum torque b2
*1 = Torque is being limited by 30.26 Power motoring
limit , 30.27 Power generating limit or the source of
30.25 Maximum torque sel .
See diagram on page 656 .
Maximum torque b3
1 = An inverter current limit (identified by bits 8…11) is
active Internal current b4
(With permanent magnet motors, synchronous
reluctance motors, and externally-excited synchronous
motors only)
1 = Maximum load angle limit is active, ie. the motor is
producing as much torque as possible Maximum load angle b5
(With asynchronous motors only)
1 = Motor pull-out limit is active, ie. the motor cannot
produce any more torque Motor pullout b6
Reserved b7
1 = Input current is being limited by the main circuit
thermal limit Thermal b8
*1 = Maximum output current (I
MAX
) is being limited Max current b9
*1 = Output current is being limited by 30.17 Maximum
current
User current b10
*1 = Output current is being limited by a calculated
thermal current value Thermal IGBT b11
*1 = Output current is being limited because of
estimated IGBT temperature IGBT
overtemperature b12
*1 = Output current is being limited because of IGBT
junction to case temperature IGBT overload b13
Reserved b14…15
1 = 1 0000h…FFFFh
