Parameter P0725 is used to define as to whether digital inputs DIN1 - DIN6 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 – P0706 (digital inputs 1–6) or P0707 – P0708 (analog inputs 1-2)
The possible settings of the individual inputs are listed in Table 3-11.
Table 3-11 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)
NOTE
If an analog input (refer to Fig. 3-33) has been configured as digital input, then the
following limit values apply: < 1.7 V DC
→ "0"
> 3.9 V DC
→ "1"
