Enable input(Safe Torque Off (STO))
• Turning off the circuit between terminals [EN1] and [PLC] or terminals [EN2] and [PLC] stops the inverter's output transistor.
(Safe Torque Off: STO)
Frequency setting
• Keypad : Can be set with UP and DOWN keys
• External Volume: Can be Set with external potentiometer (1 to 5kΩ 1/2W )
• Analog input: 0 to ±10 VDC (±5 VDC)/0 to ±100% (Terminals [12] and [V2])
0 to +10 VDC (+5 VDC)/0 to +100% (Terminals [12] and [V2])
+4 to +20 mA DC/0 to 100% (Terminal [C1])
0 to +20 mA DC/0 to 100% (Terminal [C1])
• UP/DOWN operation: Frequency can be increased or decreased while the digital input signal is ON.
• Multi-frequency : Selectable from 16 steps (step 0 to 15)
• Digital signal : 16bit parallel (binary, BCD)
• Link operation : Frequency can be set through RS-485 (Standard setting)
• Switching frequency setting: Frequency setting can be switched (2 settings) with external signal (digital input).
Remote/local switching, link switching
• Auxiliary frequency setting: Terminal [12], [C1], or [V2] input can be selected respectively as an additional input.
• Operation at a specified ratio: The ratio can be set by analog input signal.
• Inverse operation:
: The setting "0 to +10V DC/0 to 100 " can be switched to "+10 to 0V DC/0 to 100%" by external command.
: The setting "4 to +20mA DC/0 to 100 " can be switched to "+2
: The setting "4 to +20mA DC/0 to 100 " or "0 to +20mA DC/0 to 100 (Terminal [C1])" can be
switched to "+20 to 4mA DC/0 to 100 "or "+20 to 0mA DC/0 to 100 (Terminal [C1])"
• Pulse train input : Pulse input = X7 terminal, rotational direction = general terminal
Complementary output: Max. 100kHz, Open collector output: Max. 30kHz
• Pulse train input : PG interface option CW/CCW pulse, pulse + rotational direction
Complementary output: Max. 100kHz, Open collector output: Max. 25kHz
"DC +1 to +5V"
can be
adjusted with
bias and
analog input
gain
Acceleration/deceleration time
• Setting range: From 0.00 to 6000 s
• Switch: The four types of accel./decel. time can be set or selected individually (switchable during operation).
• Acceleration/deceleration pattern:
Linear accel./decel., S-shape accel./decel. (weak, free, (strong)), curvilinear accel./decel. (accel./decel. max.
capacity of constant output)
• Deceleration mode (coast-to-stop): Coast-to-stop at the operation command OFF.
• Forcible stop decel.time: Deceleration stop by the forcible stop (STOP)
Frequency limiter (Upper limit and
lower limit frequencies)
• Both upper and lower limit frequencies can be variably set in hertz.
• It is possible to choose the operation done when the set frequency drops below the lower limit from between continuous
operation at lower limit frequency and operation stop.
Bias frequency
• Bias of set reference frequency and PID command can be independently set (setting range: 0 to ± 100%).
Analog input
• Gain: Setting in the range from 0 to 200%
• Off-set: Setting in the range from -5.0 to +5.0%
• Filter: Setting in the range from 0.00s to 5.00s
Jump frequency
• Actuation points (3 points) and their common jump widths (0 to 30.0Hz) can be set.
Jogging operation
• Operation with FW D, or REV key multifunction keypad , or digital contact input ,FWD, or REV
(Exclusive accel/decel time setting, exclusive frequency setting)
Auto-restart after
momentary power failure
• Trip at power failure: The inverter trips immediately after power failure.
• Trip at power recovery: Coast-to-stop at power failure and trip at power recovery
• Deceleration stop: Deceleration stop at power failure, and trip after stoppage
• Continuous operation: Operation is continued using the load inertia energy.
• Start at the frequency selected before momentary stop: Coast-to-stop at power failure and start after power recovery at the
frequency selected before momentary stop. *1 to *3
•
Start at starting frequency: Coast-to-stop at power failure and start at the starting frequency after power recovery. *1
to *2
Current limit by hardware
• Limiting the current by hardware to prevent overcurrent trip due to sharp load change or momentary power failure which
cannot be controlled by software current limit （This function can be cancelled.）
Operation by commercial power
supply
• With commercial power selection command, the inverter outputs 50/60Hz (SW50, SW 60 . *1 to *2
•
The inverter has the commercial power supply selection sequence.
Slip compensation
• Compensates for decrease in speed according to the load. *1 to *2
Droop control
• Decrease the speed according to the load torque.
Torque limiter
•
Switchable between 1st or 2nd torque limit values
•
Torque limit, torque current limit, and power limit are set for each quadrant. *6, *7
•
Analog torque limit input
Current control
(software current limit)
• Automatically reduces the frequency so that the output current becomes lower than the preset operation level. *1 to *2
