116 Application macros
Torque control macro
This macro provides parameter settings for applications that require torque control of
the motor. Control can also be switched to speed control using a digital input. To
enable the macro, set the value of parameter
9902 APPLIC MACRO to 8 ( TORQUE
CTRL ).
For the parameter default values, see section Default values with different macros on
page 180 . If you use other than the default connections presented below, see section
I/O terminals on page 53 .

1)
Speed control: Changes rotation direction.
Torque control: Changes torque direction.
2)
0 = ramp times according to parameters 2202 and
2203 .
1 = ramp times according to parameters 2205 and
2206 .
3)

4)
The signal source is powered externally. See the
manufacturer’s instructions. To use sensors
supplied by the drive aux. voltage output, see page
55 .
Tightening torque: 0.4 N·m / 3.5 lbf·in.
Safe torque off connections (X1C:STO; not shown in
the diagram) are jumpered by default.
