6.5.3 Setting of frequency with the input from an external
contact
H
: External contact input - UP response time
H : External contact input - UP frequency steps
H : External contact input - DOWN response time
H
: External contact input - DOWN frequency steps
H : Initial up/down frequency
H : Change of the initial up/down frequency
•

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 = H / H setting time
Panel frequency decremental gradient =
H
/
H
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:
H = H = 1
