NOTE
Set Pr. 267 and a voltage/current input switch correctly, then input analog signals in accordance with the settings.
Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch in
"V" position (voltage input is selected) could cause component damage of the inverter or analog circuit of output
devices. (Refer to page 183 for details.)
Description
Turn ON the STF signal to start
forward rotation and turn it OFF
to stop.
Turn ON the STR signal to start
reverse rotation and turn it OFF
to stop.
Multi-speed can be selected according to the combination
of RH and RM signals.
The terminal 4 function is available only when the AU
signal is ON. (The operation with the frequency setting
signal of 4 to 20mA DC is available)
Common terminal for contact input terminal (sink logic) and
terminal FM.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such
as a programmable controller, in the source logic to avoid
malfunction by undesirable current.
Common output terminal for 24VDC 0.1A power supply
(PC terminal).
Isolated from terminals 5 and SE.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such
as a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Common terminal for contact input terminal (source logic).
Can be used as 24VDC 0.1A power supply.
Used as power supply when connecting potentiometer for
frequency setting (speed setting) from outside of the
inverter. (Refer to Pr. 73 Analog input selection.)
Inputting 0 to 5VDC (or 0 to 10V) provides the maximum
output frequency at 5V (10V) and makes input and output
proportional. Use Pr. 73 to switch between input 0 to 5VDC
input (initial setting) and 0 to 10VDC.
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA and makes input and
output proportional. The input signal to terminal 4 is valid
only when the AU signal is ON (terminal 2 input is invalid).
Use Pr. 267 to switch from
Current input
among input 4 to 20mA (initial
(initial status)
setting), 0 to 5VDC and 0 to
10VDC. Set the voltage/
current input switch in the "V"
position to select voltage
input (0 to 5V/0 to 10V).
Frequency setting signal (terminal 2, 4) common terminal.
Do not earth (ground).
For connecting PTC thermistor output.
When PTC thermistor protection is valid (Pr. 561  "9999"),
terminal 2 is not available for frequency setting.
