Example 1: Start/stop (1 signal) and reversal

This example shows a simple control option via two switches which should be sufficient for
many applications:
Switch S1 starts the motor in forward direction of rotation. Switch S1 in the initial position
•
stops the motor again.
Switch S2 switches the direction of rotation.

The example uses the preset I/O configuration of the inverter:
Parameter
0x2631:001 (P400.01)
0x2631:002 (P400.02)
0x2631:013 (P400.13)
Input signals
Frequency setpoint selection
Trigger Function
Constant TRUE [1] Enable inverter
Digital input 1 [11] Run
Digital input 3 [13] Invert rotation

0x2DDD
Status signals
Running [50]
Stop active [53]
Rotational direction reversed [69]
The status signals can be assigned to digital outputs.
If the inverter is enabled and no error is active, the motor can be started with the "Run" function in forward rotating direction.
①
If "Run" is set to FALSE, the motor is stopped with the stop method set in
