Sinking/Sourcing Mode for Digital Inputs
Use the wire jumper between terminals SC and SP or SC and SN to select between Sink mode, Source mode or external power
supply for the digital inputs S1 to S8 as shown in Table i.13 (Default: Sink mode, internal power supply).
NOTICE:
Do not short terminals SP and SN. Failure to comply will damage the drive.

Using External Power Supply (Sink Mode)
The high voltage level of the pulse output signal depends on the external voltage applied. The voltage must be between 12
and 15 Vdc. The load resistance must be adjusted so that the current is lower than 16 mA.

Terminals A1, A2, and A3 Input Signal Selection
Terminals A1, A2, and A3 can be used to input either a voltage or a current signal. Select the signal type using jumper S1 as
explained in Table i.14. Set parameters H3-01, H3-05, and H3-09 accordingly as shown in Table i.15.
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create the frequency
reference.
