Application Macro Motor Potentiometer - ABB ACS 400 User Manual

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.
