* These functions take effect when parameter  (frequency setting mode selection 1) is set to  or
parameter  (frequency setting mode selection 2) is set to  is enabled.
Setting of frequency with the input from an external
contact
These parameters are used to set an output frequency by means of a signal from an external device.

Adjustment with continuous signals (Parameter-setting example 1)
Set parameters as follows to adjust the output frequency up or down in proportion to the frequency
adjustment signal input time:
Panel frequency incremental gradient =  /  setting time
Panel frequency decremental gradient =  /  setting time
Set parameters as follows to adjust the output frequency up or down almost in synchronization with the
adjustment by the panel frequency command:
 =  = 1
(  /  (or  )) ≥ (  /  setting time)
(  /  (or  )) ≥ (  /  setting time)
