Zero Hz Speed Detection Signal - Omron MX2 User Manual

Using Intelligent Output Terminals

4-6-16 Zero Hz Speed Detection Signal

The inverter outputs the 0Hz speed detection signal when the inverter output
frequency falls below the threshold level (
To use this function, assign "21 (ZS)" to one of the intelligent output terminals.

• The example circuit for terminal [11] drives a relay coil. Note the use of a diode to
prevent the negative-going turn-off spike generated by the coil from damaging the
inverter's output transistor.
