• Function
These parameters are used to set an output frequency by means of a signal from an external device.
Title Function Adjustment range Default setting
External contact input - UP response
time
0.0 - 10.0 (s) 0.1
External contact input - UP frequency
steps
0.0 - FH (Hz) 0.1
External contact input - DOWN
response time
0.0 - 10.0 (s) 0.1
External contact input - DOWN
frequency steps
0.0 - FH (Hz) 0.1
Initial up/down frequency LL - UL (Hz) 0.0
Change of the initial up/down
frequency
0: Not changed
1: Setting of changed
when power is turned off
* 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.
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)
