Application macros
93
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 to 8 (TORQUE CTRL).
For the parameter default values, see section Default values with different macros
on page 142 . If you use other than the default connections presented below, see
section I/O terminals on page 40 .

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 must be powered externally.
See the manufacturer’s instructions. An
example of a connection using a two-wire
sensor is given on page
