Bipolar input contolling Start/Stop

Recommended Posts

The speed and direction are controlled using the differential input AnIn1 at terminals 2 and 3.

The direction is determined by the polarity of the input voltage.

The drive is only started if the speed reference is greater than a threshold set in 822


Operational Parameters

822 : Start Threshold





212 : Remote

213 : Remote

214 : R+L

Analogue Inputs

411 : Speed

412 : 0-10V/0-20mA

415 : Bipolar ON

416 : OFF

Digital Outputs

441 : CA1


821 : AnIn1

822 : 5%


An+ to #2

An- to #3

Gnd to #1

Enable #10 to #11 (via enable switch)

DigOut1 [#20] to RunL[#8] to RunR[#9]


When the speed input goes above the reference (822) the output of the comparator turns on both the RunR and RunL inputs enabling the drive to run in either direction. The direction is determined from the polarity of the analogue speed input.
