[TORQUE CONTROL] (tOr-)
Code Name/Description Setting range Factory settings
tOr- [TORQUE CONTROL]
This function is only accessible if [Type motor control] (Ctt) = [SVC I] (CUC) or [FVC] (FUC) .
Note:
This function cannot be used with certain other functions. Follow the instructions in see "APPLICATION FUNCT. FUn-" on page 197 .
Note:
This function is not compatible with the fault management of [load relax fault] (AnF) .
tSS [Alt Torque / v] [No] (nO)
nO [No] (nO) : Function not active. The other parameters are then not accessible.
YES [Yes] (YES) : Permanent torque limitation
LI1 [LI1] (LI1)
- .

[...] (...) : See the assignment conditions
In state 1 of the input or of the associated bit: Torque control
In state 0 of the input or of the associated bit: Speed control
tr1 [Ref. Torq.] [No] (nO)
nO [No] (nO) : Not assigned (Zero torque reference).
AI1 [AI1] (AI1) : Analog input
AI2 [AI2] (AI2) : Analog input
LCC
[HMI]
(LCC) : Graphics terminal
Mdb [Modbus] (Mdb) : Not applicable
CAn [CANopen] (CAn) : Integrated communication interface (POWERLINK)
nEt [Com. Card] (nEt) : Communication card (if present)
PG [Encoder] (PG) : Encoder input if encoder card has been inserted
100% of the reference corresponds to 300% of the rated torque.
tSd [Pref. Torque] [No] (nO)
nO
[No]
(nO) : Function not active

(...) : See the assignment conditions
With state 0 of the assigned input or bit, the prefix of the torque corresponds to the that of the reference.
With state 1 of the assigned input or bit, the torque has the opposite prefix to that of the reference.
trt
[Torque coeff]
0 to 1000% 100%
Coefficient applied to [Ref. torque] (tr1)
trP
[Time torque ramp]
0 to 99.99 s 3 s
Rise and fall times for a variation of 100% of the rated torque.
tSt [Type Stop M Contr.] [Speed.] (SPd)
SPd
[speed]
(SPd) : Speed control stop according to the normal stop configuration ( see "STOP MODE (Stt-)" on page 206 )
YES [freewheel stop] (YES) : Freewheel stop
SPn [M at 0] (SPn) : Zero torque stop, magnetization in the motor is maintained, however. This type of function is only possible if
[Motor control type] (Ctt) = [FVC] (FUC) .
SPt [time stop magmot] 0 to 3600 s 1
The parameter is accessible if [Type Stop M Contr.] (tSt) = [M at 0] (SPn) .
Rotation time after a stop, important for fast restart.
dbp [M. ctrl. pos bandw.] 0 to 2x
[Max. output freq.] (tFr)
10 Hz
Positive deadband.
Value added algebraically to the frequency reference.
Example for dbp = 10:
• If reference = 50 Hz: 50 + 10 = 60
•
If reference = -50 Hz: - 50 + 10 = - 40
dbn [M. ctrl. neg. bandw.] 0 to 2x
[Max. output freq.] (tFr)
10 Hz
Negative deadband.
Value subtracted algebraically from the frequency reference.
Example for dbn = 10:
•
If reference = 50 Hz: 50 - 10 = 40
•
If reference = -50 Hz: - 50 - 10 = - 60
rtO [M ctrl timeout] 0 to 999.9 s 60
Period of time after the automatic stop of the torque-controlled mode in the event of a fault or alarm.
tOb [M ctrl mgt] [Alarm] (ALrM)
Response of the inverter after the expiry of the time [M ctrl Timeout] (rtO) .
ALrM
[Alarm]
(ALrM)
FLt [Fault] (FLt) : Fault when stopping in freewheel stop.
Parameter that can be modified during operation or when stopped.
