264 Parameters
Displays the torque controller limitation status word.
This parameter is read-only.

0000h…FFFFh
Torque limitation status word.
1 = 1
Defines the minimum allowed speed.
WARNING!
This value must not be higher than
WARNING!
In frequency control mode, this limit is not
effective. Make sure the frequency limits (
and
) 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

0
Undervoltage
*1 = Intermediate DC circuit undervoltage
1
Overvoltage
*1 = Intermediate DC circuit overvoltage
2
Minimum torque *1 = Torque is being limited by
or the source of
. See
diagram on page
3
Maximum torque *1 = Torque is being limited by
.
See diagram on page
.
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
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.
