264 Parameters
30.02 Torque limit status Displays the torque controller limitation status word.
This parameter is read-only. -
0000h…FFFFh Torque limitation status word. 1 = 1
30.11 Minimum speed Defines the minimum allowed speed.
WARNING! This value must not be higher than 30.12
Maximum speed .
WARNING! In frequency control mode, this limit is not
effective. Make sure the frequency limits ( 30.13 and
30.14 ) are set appropriately if frequency control is
used.
WARNING! In a master/follower configuration, do not
set maximum and minimum speed limits with the same
sign on a follower drive. See section
Master/follower

46.01
No. Name/Value Description Def / FbEq16
Bit Name Description
0 Undervoltage *1 = Intermediate DC circuit undervoltage
1 Overvoltage *1 = Intermediate DC circuit overvoltage
2 Minimum torque *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 592 .
3 Maximum torque *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 592 .
4 Internal current 1 = An inverter current limit (identified by bits 8…11) is active
5 Maximum load
angle (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
6 Motor pullout (With asynchronous motors only)
1 = Motor pull-out limit is active, ie. the motor cannot produce any
more torque
7 Reserved
8 Thermal 1 = Input current is being limited by the main circuit thermal limit
9 Max current *1 = Maximum output current ( I
MAX
) is being limited
10 User current *1 = Output current is being limited by 30.17 Maximum current
11 Thermal IGBT *1 = Output current is being limited by a calculated thermal current
value
12 IGBT
overtemperature *1 = Output current is being limited because of estimated IGBT
temperature
13 IGBT overload *1 = Output current is being limited because of IGBT junction to case
temperature
14…15 Reserved
*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.
