When the signals are simultaneously input
• When the clear signal, and an UP or a DOWN signal are simultaneously input, the clear signal
takes priority.
• When an UP signal and a DOWN signal are simultaneously input, the frequency changes
according to the up rate and the down rate.
■
Setting example 1: Increase or decrease by the continuous signals
When you want to increase or decrease the output frequency in proportion to the input time of the
UP and DOWN signals, set the parameters as shown below:
UP/DOWN frequency increase inclination=Setting time for <F265>/<F264>
UP/DOWN frequency decrease inclination=Setting time for <F267>/<F266>
When you want to increase or decrease the output frequency almost in synchronization with the
increase or decrease in the UP/DOWN frequency command, set the parameters as shown below:
<F264>=<F266> = "0.1"
<FH>/<ACC>
≧
(Setting time for <F265>/<F264>)
<FH>/<dEC>
≧
(Setting time for <F267>/<F266>)
■
Setting example 2: Increase or decrease by the pulse signals
When you want to increase or decrease the frequency per pulse stepwise, set the parameters as
shown below:
<F264>, <F266>
≦
Pulse ON time
<F265>, <F267> = Frequency that increases or decreases per pulse
However, no response is obtained to the pulse below the time set for <F264> and <F266>. Set
12 ms or more for the clear signal.
Memo
• The next number of each function number ("89", "91", or "93") is an inversion signal.
• When <F702: Free unit multiplication factor>="1.00", you can make setting in steps of 0.01 Hz.
