10. INPUT - OUTPUT FEATURES
10.1. Digital Input Features (Terminals 6 to 13)
All digital inputs are galvanic insulated with respect to zero volt of the inverter control board (ES778). Consider
power supply on terminals 14 and 15 before activating the inverter digital inputs.
Depending on the position of jumper J10, signals may be activated both to zero volt (NPN-type command) and
to + 24 Volts (PNP-type command).
The figure below shows the different control modes based on the position of jumper J10.
Auxiliary power 24 VDC (terminal 15) is protected by a self-resetting fuse.
Figure 40: Control modes for the digital inputs.
NOTE
Terminal 14 (CMD – digital input zero volt) is galvanically isolated from terminals
1, 20, 22 (CMA – control board zero volt) and from terminal 25 (MDOE =
emitter terminal of multifunction digital output).
The operating condition of the digital inputs is indicated by parameter M08 (IFD SW) or parameter M11 (VTC
SW) in the Measure submenu. Digital inputs (except form terminal 6 and terminal 8) are disabled if parameter
C21 (IFD SW) or C14 (VTC SW) is set to REM. In that case, the command is sent through serial communication.
If parameter C21 (IFD SW) or C14 (VTC SW) is programmed to Kpd, input 7 command is sent via keypad
(START key).
