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
