 : Terminal input enabled
 : Operation panel input enabled (including
LED/LCD option input)
 : 2-wire RS485 communication input
 : 4-wire RS485 communication input
 : Communication option input

Note 1: If speed commands (analog signal or digital input) are switched in line with preset speed operations, select the
terminal board using the frequency setting mode selection 1 HOQF.
⇒ Refer to 3) or Section 5.5.
Note 2: When using an optional extension LED panel or extension LCD panel, set EOQF= to enable the entry of
commands from the extension and graphic panel.
2)Preset speed frequency setting
Set the speed (frequency) of the number of steps necessary.

Example of preset speed contact input signal
It sets up, when using the optional circuit board.
• Function
A maximum of 15 speed steps can be selected just by switching an external contact signal. Preset speed
frequencies can be programmed anywhere from the lower limit frequency NN to the upper limit frequency WN.
• Function
These parameters adjust the output frequency according to the externally applied analog signal (0~10Vdc
voltage, 4(0)~20mAdc current) and the entered command for setting an external contact frequency.
