DC injection braking
Starts at a frequency lower than that in deceleration via the STOP command, at a
value set lower than that during operation, or via an external input. (Level and time
settable.)
Protective functions
Overcurrent, overvoltage, undervoltage, electronic thermal, temperature error,
ground-fault overcurrent at power-on state, overload limit, incoming overvoltage,
external trip, memory error, CPU error, USP trip, communication error, overvoltage
protection during deceleration, momentary power interruption protection,
emergency shutoff
Input signal
Digital
Operator
signal
Frequency
settings
Setting with the FREQ adjuster and the Increment/Decrement keys on the Digital
Operator, variable resistance from 1 to 2 kΩ (2 W), 0 to 10 V DC (input impedance
10 kΩ), 4 to 20 mA (input impedance 250 Ω), communication through an RS-485
port (ModBus communication).
(Simultaneous inputs of FV/FI are not acceptable. Also, do not connect the signal
lines for inputs FV and FI simultaneously.
Forward/
Reverse
Run/Stop
Forward/Stop via the RUN and STOP/RESET keys (parameter selection for
Forward or Reverse), Reverse/Stop available at the time of multi-function input
allocation (selectable from 1NO or 1NC), Run/Stop through external
communication.
Multi-function input

(external DC injection braking), SET (2nd function), 2CH (2-step acceleration/
deceleration), FRS (free run), EXT (external trip), USP (USP function), SFT (soft
lock), AT (analog current input function selection), RS (reset) , PTC (thermistor
input) , STA (3-wire startup), STP (3-wire stop), F/R (3-wire forward/reverse), PID
(PID selection), PIDC (PID integral reset), UP (UP of UP/DWN function), DWN
(DWN of UP/DWN function) , UDC (data clear of UP/DWN function), OPE (forced
OPE mode), ADD (frequency addition), F-TM (forced terminal block), RDY
(operation ready), SP-SET (special setting), EMR (emergency shutoff)
