TORQUE LIMIT STATUS
(30.02)
Default: Read Only
Range: 0000h - FFFFh
Displays the torque controller limitation status word.
This parameter is read-only.
Bit Name Information
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.
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.
4
Internal current
1 = An inverter current limit (identified by
bits 8 - 11) is active
5
Load angle
(With permanent magnet motors and
synchronous reluctance motors only)
1 = Load angle limit is active, ie. the motor
cannot produce any more torque
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.
MAXIMUM SPEED
(30.12) Default: 0.00 RPM
Range: -30000.00 to +30000.00 RPM
Defines the maximum allowed speed. Value is adjustable from 99.09
motor nominal speed or lower.
WARNING: This value must not be lower than 30.11 Minimum speed.
