Step of Up/Down Function (Hz):
5-09： ： ： ： Up/Down (Hz) 0.00 – 5.00
There are two modes covered below:
(1) 5-09 = 0.00, the function is disable. The operation is just as the original one. As UP terminal is
ON, the frequency increases while the DOWN terminal is ON, the frequency decreases. (Refer to
the following graph).
(2) 5-09 = 0.01 to 5.00, UP/ DOWN terminal ON, that equivalent to increase/ decrease the
frequency of 5-09. If the pressing is over 2second, revive the original UP/DOWN mode (Please
refer to the following diagram)
Encoder Impulse Ratio： ： ： ：
5-10 Impulse input frequency time ratio
When frequency source 1-06 be setting as 0005, the impulse signal frequency will be
according to this parameter to decide to the real inside frequency of inverter.
The inside calculate formula : Frequency = S5(impulse frequency)*5-10(times ratio)
For example, when S5 impulse is 1KZ （ 1000 ） , and 5-10 be setting as 1.50 times. The inverter
frequency command is 1000*1.5=1500=15.00HZ. The frequency accuracy of S5 is by base
of 100, 1K(1000) present 10.00 HZ.
