Example 6: Remote Start/Stop (2-wire) & Speed Changes via external source with 3

Present Speeds

This configuration is generally used when the inverter is controlled via a remote source such as a PLC. It can also

be used with a maintained switch when it is desirable to have the drive restart on restoration of power. It should not

be used where the safety of the attending personnel might be threatened by automatic restart. Up to three speeds

can be selected by using the switches SW1-SW2 to select the desired speed.

Operation

Close (K1) to run in the forward direction.

Close (K2) to run in the reverse direction.

When both relays are closed, the inverter will fault on a External Fault and stop operation of the

motor.

The frequency of the inverter will be proportional to the signal level on terminal FV or FI

( 0Vdc=0Hz, 5Vdc=30Hz & 10Vdc =60Hz).

By closing any of the switches (SW1-SW2) and closing either (K1) or( K2) to determine the direction,

the inverter will run at a present speed.

When the LOCAL/REMOTE key is pressed, the inverter will act as Example 1.
