PARAMETERS
(4) Gain adjustment [Pr.301], [Pr.303]
The gain may be set in either of the following two ways:
!
How to set the output frequency at the input signal of 999 (BCD code) or FFFH (binary)
(The factory setting is 60Hz (1500r/min. for the FR-V500 series) for this input signal. )
!
How to set the BCD code or binary value as the output frequency (output speed) setting
When "9999" is set in Pr.301 (BCD code) or Pr.303 (binary), the digital input value is set (unchanged)
as the output frequency (output speed).
(For example, to set the output frequency to 120Hz at the BCD code input of "120")
CAUTION
The maximum output frequency (maximum operation speed) for operation with the digital input is
the "gain" value set in Pr.301 and Pr.303.
To set the maximum output frequency to 60Hz or more with the FR-A500(L)/F500(L) series and the
maximum operation speed to 1500r/min or more with the FR-V500 series, change the "gain" from
the control panel or parameter unit.
