Connection method 1) a-contact input

Inverter

Input terminal

CC

a-contact switch

Sink setting

$This function is activated when the input terminal and

CC(common) are short-circuited. Use this function to specify forward/reverse run or a preset speed operation.

2) Connection with transistor output

Inverter

Input terminal

CC

Programmable controller

$Operation can be controlled by connecting the input and CC (common) terminals to the output (no-contacts switch) of the programmable controller. Use this function to specify forward/reverse run or a preset speed operation. Use a transistor that operates at 24Vdc/5mA.

* Interface between programmable controller and inverter

 

Note: When using a programmable controller with open collector outputs for control, connect it to the P24/PLC

 

terminal, as shown in the figure below, to prevent the inverter from malfunctioning because of current

 

flowing in.
