Running, operation
Key operation: Start and stop with and keys (standard keypad)
Start and stop with ， ，and keys (optional
multi-function keypad)
External signals: Forward (reverse) rotation, start/stop commands
(capable of 3-wire operation), (digital input) coast to stop
command, external alarm, alarm reset, etc.
Link operation: Operation through RS-485, field bus communication
(option)
Run command switching: Remote/local switching, link switching
Frequency setting
Keypad operation: Using and keys
External potentiometer: Using external frequency command
potentiometer (external resistor of 1 to 5 kΩ,
1/2 W)
Analog input: Voltage input (terminal [12], [V2], [C1] (V3 function))
0 to ±10 VDC (±5 VDC)/0 to ±100%
0 to +10 VDC (+5 VDC)/0 to +100%
(+1 to +5 VDC can also be adjusted with bias, analog
input gain)
Voltage input (terminal [C1] (C1 function))
4 to 20 mA DC/0 to 100%, 0 to 20 mA DC/0 to 100%
4 to 20 mA DC/-100 to +100%, 0 to 20 mA DC/-100 to
+100%
UP/DOWN operation: Frequency can be increased or decreased while
the digital input signal is ON.
The frequency is cleared with digital input “STZ”.
Multistep frequency selection: Selectable from 16 different frequencies
(step 0 to 15)
Pattern operation: The inverter runs automatically according to the
previously specified run time, rotation direction,
acceleration/deceleration time and reference
frequency. Up to 7 stages can be specified.
Link operation: Setting through RS-485, field bus communication (option)
(built in as standard)
Frequency setting switching: Two types of frequency settings can be
switched with an external signal (digital
input).
Remote/local switching, link switching
Auxiliary frequency setting: Can be selected by adding and entering the
respective terminal [12], [C1], or [V2] inputs.
Operation at a specified ratio: The ratio can be set with an analog input
signal.
