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 (
MOTOR POT
).
Connection example:
*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.
Motor potentiometer default parameter values:
Input signals Output signals
• Start, stop and direction
(DI1,2)
• An. output AO: Frequency
• Reference up (DI3) • Relay output 1: Fault
• Reference down (DI4) • Relay output 2: Running
• Preset speed selection (DI5)
