Siemens 420 manual P0701 P0703 digital inputs 1-3 or P0707 P0703 analog input, Example

3 Functions Issue 07/04

Parameter P0725 is used to define as to whether digital inputs DIN1 – DIN3 are logical "1" when appropriately connected to 0 V or 24 V. The logical states of the digital inputs can be de-bounced using P0724 and read-out using parameter r0722 (BICO monitoring parameter). Further, this parameter is used to parameterize BICO for the digital inputs (refer to BICO parameterization in the following Section).

P0701 – P0703 (digital inputs 1–3) or P0707 – P0703 (analog input)

The possible settings of the individual inputs are listed in Table 3-10.

Table 3-10 Parameters P0701 – P0706

Parameter value	Significance
0	Digital input disabled
1	ON / OFF1
2	ON+reverse / OFF1
3	OFF2 – coast to standstill
4	OFF3 – quick ramp-down
9	Fault acknowledge
10	JOG right
11	JOG left
12	Reverse
13	MOP up (increase frequency)
14	MOP down (decrease frequency)
15	Fixed setpoint (direct selection)
16	Fixed setpoint (direct selection + ON)
17	Fixed setpoint (binary-coded selection + ON)
25	Enable DC braking
29	External trip
33	Disable additional frequency setpoint
99	Enable BICO parameterization

Example:

An ON/OFF1 command should be realized using digital input DIN1.

P0700 = 2 Control enabled via terminal strip (digital inputs)

P0701 = 1 ON/OFF1 via digital input 1 (DIN1)
