Parameter
How to find the set frequency for override:
Set frequency [Hz]
Main speed set frequency [Hz]: Terminal 1, 4 or multi-speed setting
Compensation amount [%]: Terminal 2 input
Example Pr. 73 = 5
The set frequency changes as shown below according to the terminal 1 (main speed) and
terminal 2 (auxiliary) inputs.
Fig. 6-119: Set frequency in dependence on the terminal 1 and terminal 2 signals
NOTES When the Pr. 73 setting was changed, check the voltage/current input switch setting. Differ-
ent setting may cause a fault, failure or malfunction. (Refer to page 6-188 for setting.)
The AU signal must be turned on to use the terminal 4.
When inputting compensation to multi-speed operation or remote setting, set "1" (compen-
sation made) to Pr. 28 "Multi-speed input compensation selection". (Initial value is "0".)
