Siemens 420 manual Recommended wiring for the factory setting

3 Functions Issue 07/04

If the various prerequisites are fulfilled and the appropriate conditions present, then after the motor has been connected and the power connected, then the following is possible with the factory setting:

The motor can be started and stopped	(via DIN1 with external switch)
The direction of rotation can be reversed	(via DIN2 with external switch)
Faults reset	(via DIN3 with external switch)
A frequency setpoint can be entered	(via ADC with external
	potentiometer, default setting of
	the ADC: unipolar voltage input)
The frequency actual value can be output	(via DAC,
	DAC output: current output)

The potentiometer and the external switches can be connected through the drive inverter internal power supply, as shown in Fig. 3-13.

If settings have to be made which go beyond the factory setting, then depending on the complexity of the application, when commissioning the drive system, the particular function description as well as the parameter list including function charts must be carefully taken into consideration.
