I/O Logic Select - Inputs
The Drive offers the possibility to operate the Digital Inputs in either PNP (Positive Logic) or NPN (Negative Logic).
I/O Logic Select Inputs - Setup Process
Below is the setup process for selecting the logic of the Digital Inputs.
Decide which configuration of logic you will be using. The default is positive logic (P1-43 = 0)
While the drive is powered off make the necessary wiring adjustments so that your I/O wiring matches your logic selection.
Set P1-43 to the relevant value.

Power on the drive.
Caution
When powering on the drive after switching logic always make sure the Safe Torque Off inputs are not closed so the drive can not start. Incorrect wiring/parameter settings could cause the car start start unintentionally.
Check P0-01 and P0-02 to make sure that your Digital Inputs are in the correct state and are changing state properly.
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P0-01 | Digital Input 1 to 5 Status | N/A | 0 | 0 ... 31 | RO | N | N/A | 1 | 2012h | 0 | 10001 |
P0-02 | Digital Input 6 to 10 Status | N/A | 0 | 0 ... 31 | RO | N | N/A | 1 | 2012h | 0 | 10002 |
P1-43 | Positive/Negative Logic Select | N/A | 0: Positive Logic | 0: Positive Logic 1: Negative Logic | RW | N | N/A | 1 | 208Fh | 0 | 143 |
Changes the control logic for all Digital Inputs (including the Universal Encoder module terminals Daux1 and Daux2).
Setting | Logic |
