Application macros
62
Motor Potentiometer macro
This macro provides a cost-effective interface for PLCs that vary the speed of the
drive using only digital signals. To enable the macro, set the value of parameter 9902
to 4 (MOTOR POT).
For the parameter default values, see section Default parameter values with different
macros on page 65. If you use other than the default connections presented below,
see section I/O terminals on page 34.

SCR Signal cable shield (screen)
AI Not in use by default: 0…20 mA
GND Analog input circuit common
+10V Reference voltage: +10 VDC, max. 10 mA
+24V Auxiliary voltage output: +24 VDC, max. 200 mA
GND Auxiliary voltage output common
DCOM Digital input common
DI1 Stop (0) / Start (1)
DI2 Forward (0) / Reverse (1)
DI3 Frequency reference up
1)
DI4 Frequency reference down

1)
If DI3 and DI4 are both active or inactive, the
frequency reference is unchanged.
The existing frequency reference is stored
during stop and power down.

Tightening torque = 0.22 N·m / 2 lbf. in
3)
Tightening torque = 0.5 N·m / 4.4 lbf. in.
