*	The H parameter (VI/S3 terminal function selection) is used to specify a function
	for the VI/S3 input terminal. The FCHG parameter (frequency command forced
	switching) makes it possible to use both the analog input frequency signal and the
	frequency signal set with the internal potentiometer, which can be switched by
	activating or deactivating the input terminals.
	See 5.1 for details.

Note: The current input and voltage input functions cannot be used at the same time.

(4) Setting the frequency by serial communications (HOQF : )

The frequency can also be set from a higher-order external control device via optionally available communications conversion units (RS2001Z, RS20035, RS2002Z and RS4001Z).
