YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 235
5.7 H: Terminal Functions
H parameters are used to assign functions to the external terminals.
H1: Multi-Function Digital Inputs
H1-01 to H1-08: Functions for Terminals S1 to S8
These parameters assign functions to the multi-function digital inputs. The various functions and their settings are listed
below in Table 5.35.
