Note: Assign the AU signal to any of the terminals using the input terminal function
selection (Pr. 180 to Pr. 183).
* Used as a contact input signal common terminal for the 400V class by switching
between sink logic and source logic. (Refer to page 23).
Terminal
Name
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.
Combine the RH, RM and RL signals
as appropriate to select multiple
speeds.
Turn on the MRS signal (20ms or
longer) to stop the inverter output.
Used to shut off the inverter output to
bring the motor to a stop by the
electromagnetic brake.
Used to reset the protective circuit activated. Turn on the
RES signal for more than 0.1 second then turn it off.
Common to the contact input terminals and terminal FM.
Common output terminal for 24VDC 0.1A power output
(PC terminal).
When transistor output (open collector output), such as a
programmable controller (PLC), is connected, connect the
external power supply common for transistor output to this
terminal to prevent a fault caused by undesirable current.
This terminal can be used as a 24VDC, 0.1A power
output.
5VDC, permissible load current 10mA
By entering 0 to 5VDC (0 to 10VDC), the maximum output
frequency is reached at 5V (or 10V) and I/O are
proportional. Use Pr. 73 to switch between input 0 to
5VDC (factory setting) and 0 to 10VDC. Input resistance
10k Ω . Maximum permissible voltage 20V.
By entering 4 to 20mADC, the maximum output frequency
is reached at 20mA and I/O are proportional. This input
signal is valid only when the AU signal is on. Input
resistance 250Ω. Maximum permissible current 30mA.
Common to the frequency setting signals (terminal 2, 1 or 4).
Do not connect to the earth.
