frequency/1000 Voltage/Frequency characteristics V/f characteristics (constant/reduced torque) Overload current rating 150% for 1 min Acceleration/Deceleration time 0.01 to 3000 s (line/curve selection), 2nd acceleration/deceleration setting available Carrier frequency modification range 2 to 12 kHz 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.
