118 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 176. If you use other than the default connections presented below, see section
I/O terminals on page 51.

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)
360 degree grounding under a clamp.
4)
The signal source is powered externally. See
the manufacturer’s instructions. To use
sensors supplied by the drive aux. voltage
output, see page 53.
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.
