Maximum torque Q4

  • Menu: 4.2.12-2.4

Description

Operation of the drive train can be divided into 4 quadrants. The quadrants are defined as follows:

  • Quadrant 1: Speed positive, torque positive
  • Quadrant 2: Speed negative, torque positive
  • Quadrant 3: Speed negative, torque negative
  • Quadrant 4: Speed positive, torque negative

Limit value of the torque profile value in the 4th quadrant.

The following parameters are set:

Parameter

Meaning

Source

Specifies the source from which the maximum torque for the quadrants is retrieved.

PO data format

Length of the process output data word

Value

Current limit value of the torque profile value that is used in the following drive functions:

  • FCB 05 Speed control
  • FCB 06 Interpolated speed control
  • FCB 07 Torque control
  • FCB 08 Interpolated torque control
  • FCB 09 Position control
  • FCB 10 Interpolated position control

If the Local value setting has been specified for the Source parameter, the user can specify the value locally. The local value is stored in a non-volatile memory.

INFORMATION: Please note that the torque is additionally limited close to the maximum speed in the FCB 07 and FCB 08 drive functions (see the explanation "Torque control speed limitation" in the Torque parameter in the Setpoint value connection parameter group).
