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