3. Lag time of torque controller TCTLG (_TCON)
the lag time is optimized for the motor and no adjustment is necessary.
4. P gain of torque controller TCG (_TCON)
The gain is optimized for the motor and no adjustment is necessary.
8.3 Speed Control Mode
The speed controller obtains its reference value from the inputs n1* and n2*. Input n2 is only
required for precontrol in position control and is otherwise disabled. The speed controller
generates a torque reference value which is transmitted to the torque controller.
Relevant Parameters:
1. Torque limit TCMMX is the only parameter from the _TCON area which is set to suit the
requirements of specific applications (see “Torque Control Mode”).
2. Maximum Values of Speed
SCSMX (_SCON) Limit of speed controller
MOSNM (_MOT) Rated speed of motor (SM and ASM)
MOSMX (_MOT) Maximum speed of motor (only in the case of ASM, only for
speed limitation)
The parameter SCSMX limits the maximum speed of the motor. The maximum value for
this parameter is obtained from the data of the motor in use. In the case of synchronous
motors this is the rated speed MOSNM and in the case of asynchronous motors the maximum
speed MOSMX (in the field weakening area).
The parameters for SCSMX speed limitation are always set to be application-specific.

1 (AH2):
1. Asynchronous motors can only be operated up to the rated motor speed MOSNM (_MOT)
and field weakening cannot be used.
2. Motor parameter K14 must be used to limit operating speed (not SCSMX).
