Note:
(1) Before the inverter is put into use, the terminal wiring and all jumper switches on the control board
should be set correctly.
(2) DIP switch:
Slot A expansion card takes VH6-A100 as an example. It has three dialing status bits to determine the
type of analog input and output signals.
S1: AI1 OFF = 0 - 10V, ON = 0 - 20mA, default is OFF
S2: AI2 OFF = 0 - 10V, ON = 0 - 20mA, default is OFF
S3: AO1 OFF = 0 - 10V, ON = 0 - 20mA, default is OFF
(3) The dial switch needs to adjustment after the inverter is completely powered off and the expansion card is
pulled output, and the expansion card is not allowed to be hot plugged.
2-4-2. Analog I/O wiring
(1) Analog input terminal AI wiring
AI1/AI2 terminal receives analog signal input, and AI1/AI2 dial switch can select input voltage (0 ~ 10V) or
current (0 ~ 20mA). The specific wiring is shown in the figure below:
(2) Analog output terminal AO wiring
AO1 external analog meter can indicate a variety of physical quantities, AO1 dial switch can select output
voltage (0 ~ 10V, external load 2KΩ – 1MΩ) or current (0 ~ 20mA, external load less than 500Ω). The terminal
wiring mode is shown in the figure below.
