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
• Function
These parameters are used to set an output frequency by means of a signal from an external device.

* These functions take effect when parameter HOQF (frequency setting mode selection 1) is set to or
parameter
H (frequency setting mode selection 2) is set to is enabled.
■ 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
(
HJ/CEE (or H)) ≥ (H/H setting time)
(
HJ/FGE (or H)) ≥ (H/H setting time)
