252 Parameters
30.02 Torque limit status Displays the torque controller limitation status word.
This parameter is read-only.
0b0000
0b0000…0b1111 Torque limitation status word. 1 = 1
30.09 Current limit
monitor time
Defines the drive current limit monitor time after which action
is taken as specified in the parameter 30.10.
10.00
0...120s Current limit monitor time. 100=1
30.10 Current limit actions Selects how the drive reacts when the drive reaches the
current limit (30.17 Maximum current) and exceeds the
monitor time set by parameter 30.09 Current limit monitor
time.
No action
No action None (current limit action disabled). 0
Warning The drive generates an A8B6 Current limit warning. 1
Fault The drive trips on fault 8009 Current limit.2
30.11 Minimum speed Defines the minimum allowed speed.
WARNING! This value must not be higher than 30.12
Maximum speed.
WARNING! In speed control mode only. In frequency
control mode, use frequency limits (30.13 and 30.14).
-1500.00 rpm
-30000.00…
30000.00 rpm
Minimum allowed speed. See par.

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 30.19 Minimum torque 1, 30.26 Power
motoring limit, or 30.27 Power generating limit
3 Maximum torque *1 = Torque is being limited by 30.20 Maximum torque 1, 30.26 Power
motoring limit, or 30.27 Power generating limit
4 Internal current 1 = An inverter current limit (identified by bits 8…11) is active
5 Load angle Not applicable
6 Motor pullout (With asynchronous motors only)
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…11 can be on simultaneously. The bit typically
indicates the limit that is exceeded first.
