Example: Start/stop (1 signal) and reversal
This example shows a simple control option via two switches which should be sufficient for many applications:
–
The switch S1 starts the motor in forward rotating direction. The switch S1 in the initial position stops the motor again.
–
The switch S2 switches the direction of rotation.

①
|
If the inverter is enabled and no error is active, the motor can be started with the "Run" function in forward rotating direction.
|
|
②
|
If "Run" is set to FALSE, the motor is stopped with the stop method set in 0x2838:003 (P203.03). In the example: Stop with standard ramp.
