Input terminal
* 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.
Inverter
A-contact switch Sink setting
2) Connection with transistor output
* 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.
CC
Input
terminal
Inverter
Programmable controller
* Interface between programmable controller and inverter
Note: When using a programmable controller with open collector outputs for control, connect it to the
PCL terminal, as shown in the figure below, to prevent the inverter from malfunctioning
because of a current that flows in.
Also, be sure to turn the SW4 slide switch to the PLC position.
