Application macros 113
Motor potentiometer macro
This macro provides a cost-effective interface for PLCs that vary the speed of the
motor using only digital signals. To enable the macro, set the value of parameter
to 4 (
For the parameter default values, see section
Default values with different macros
on
. If you use other than the default connections presented below, see section
.

2)
1)
If DI3 and DI4 are both active or inactive, the
speed reference is unchanged.
The existing speed reference is stored during stop
and power down.
2)
360 degree grounding under a clamp.
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.
