(2) Gain adjustment
The gain may be set in either of the following two ways:
How to set the output frequency when the input signal is 999 or 9999 (BCD code), and FFF
FFFF
(binary).
H
⋅ BCD code input .. Set using Pr. 301.
⋅ Binary input ........ Set using Pr. 303.
The output frequency is factory-set to 60Hz (EC version : 50Hz).

How to set the BCD code or binary value as the output frequency setting
When "9999" is set in Pr. 301 (BCD code) or Pr. 303 (binary), the digital input value is set as the output
frequency.
(For example, to set the output frequency to 120Hz when the BCD code input is

The maximum output frequency for
operation with the digital input
signal is the "gain" value set in
Pr. 301 and Pr. 303.
To set the maximum output
Pr.304=0,2
frequency at 60Hz (EC version :
50Hz) or more, change
the operation panel.
REMARKS
When this setting method is used, "bias" setting (Pr. 300 or
Pr. 302) cannot be made.
