for details.
Setting 6: Jog Reference Selection
The Jog frequency set in parameter d1-17 becomes the frequency reference when the input terminal closes.
Frequency Reference on page 124
Setting C: Analog Terminal Input Selection (Terminals A1 and A2)
When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analog
terminals.
Setting F: Not Used (Through Mode)
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in
the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or MEMOBUS/
Modbus communications.
Settings 10 and 11: Up/Down Function
The Up/Down function allows the frequency reference to be set by two push buttons when one digital input is programmed
as the Up input (H1-oo= 10) to increase the frequency reference and the other digital input is programmed as the Down input
(H1-oo= 11) to decrease the frequency reference.
The Up/Down function takes priority over the frequency references from the HOA keypad, the analog inputs, and the pulse
input (b1-01 = 0, 1, 4). When using the Up/Down function, references provided by these sources will be disregarded.
The inputs operate as shown in the table below:
