Application Macro Motor Potentiometer
This macro provides a cost-effective interface for PLCs that vary the speed of
the drive using only digital signals.
The value of parameter 9902 is 4.
Input signals
• Start, stop and direction (DI1,2)
• Reference up (DI3)
• Reference down (DI4)
• Preset speed selection (DI5)
mA
*Note!
•
If both DI 3 and DI 4 are active or inactive, reference is kept stable.
•
Reference is stored during stop or power down condition.
•
Analogue reference is not followed when motor potentiometer is
selected.
