Item	Detailed Specifications
Acceleration／Deceleration time	Setting Range: Adjustable within the range of 0.00 to 6000 s. Switching: Four acceleration/deceleration times can be set independently and selected for switching during operation. Acceleration/Deceleration modes: Linear acceleration/deceleration, S-curve acceleration/deceleration (weakened, arbitrary adjustments possible via function codes), curve acceleration/deceleration. Deceleration mode (free running): When the operation command is set to OFF, the system halts free running. Forced stop deceleration time: A dedicated deceleration time is used to halt during a forced stop (STOP). S-curve is disabled during forced stops. JOG specific acceleration/deceleration Time: Acceleration/deceleration time can be switched to 0 by canceling BPS (Block Pulse Speed) through operation.
Frequency limits (Upper limit, Lower limit frequency)	Both upper and lower frequencies can be set in Hz. When frequency is below the lower limit, select whether to continue operation or stop as per lower frequency. Settings can be configured through analog inputs (terminals [12], [C1]).

Analog Input	Gain: Adjustable within the range of 0 to 400%. Compensation: Adjustable within the range of -5.0% to +5.0%. Filter: Adjustable within the range of 0.00s to 5.00s. Polarity selection (±/+).
Jump frequency	Action points (6 points) and general jump magnitude (0 to 30 Hz) can be set.
Timed operation	The system will stop after running for the time set via the keypad. (Single cycle operation.)
Restart after momentary power failure	Power failure trip: Instantaneous trip upon power failure. Power-on trip: Free running during power failure, and trip upon restoration of power. Deceleration stop: Decelerates to a stop during power failure, and trips afterward. Continuous operation: Utilizes the load inertia energy to maintain operation. Frequency starts before momentary power failure: Free running during a power failure, and restart at the frequency of the momentary power failure when power is restored. Start at the startup frequency: Free running during power failure, and restart at the startup frequency upon power recovery. Frequency start upon power restoration: Free running during power failure, and retrieval of speed to restart after power restoration.
Current limitation (Hardware current limitation)	To prevent overcurrent trips caused by large load variations or momentary power failure that cannot be responded to by software current limits, hardware current limits are applied. (This function can be disabled.)
Current limitation (Software current limitation)	Automatic frequency reduction to keep output current below the preset action value. (This function can be turned off.) Selectable operation modes (only during constant speed operation, or during both acceleration and constant speed operation).
Commercial switch operation	Commercial switching command for outputting 50/60 Hz ([SW50], [SW60]). Built-in commercial switching sequence.

Regenerative Braking Avoidance Control	During deceleration, if the DC intermediate voltage/torque calculation exceeds the regenerative avoidance value, overvoltage trips are prevented by extending deceleration time automatically. (Specify whether to enforce deceleration after exceeding three times the deceleration time.) During constant speed operation, if the torque calculation exceeds the regenerative avoidance value, overvoltage trips are prevented by controlling frequency increases.

Main circuit power-off detection	The inverter cannot operate when the AC input power (main power) is not connected. In cases such as using a PWM inverter or DC bus power supply, set the main circuit power-off detection to "disabled".	－	－
Forced operation (fire mode)	Warnings other than severe warnings will be ignored, and a forced retry will occur.	Fod	－

Note1: These symbols appear on the keypad LED or LCD.

Note2: Y1 indicates that the relay output 30A/B/C operates when the protection function is activated. Y2 indicates that, depending on the minor fault setting, the relay output does not operate when the protection function is activated.

Note1

The storage temperature is based on the assumption value of a short transport duration.

Note2

Even if humidity is within acceptable levels, condensation or freezing may occur in areas with significant temperature fluctuations. Please refrain from storing in such conditions.
Please avoid installing the inverter in environments where lint, cotton fibers, damp dust, or dirt may obstruct the heat sink. If usage in such environments is necessary, install the inverter in a cabinet to protect it from damage. Prevent the ingress of lint and similar particles.

Precautions for Temporary Storage

1.

Do not place directly on the floor.
2.

If the surrounding atmospheric conditions do not meet the above storage requirements, seal the product in polyethylene cloth or similar packaging for storage.
3.

If moisture exposure is a concern, please include a desiccant (such as silica gel) and seal with polyethylene cloth or similar material.

Precautions for Long-Term Storage

If the product is stored for more than 3 months, the surrounding temperature should be maintained between -10 and +30℃ (14 to 86℉). This is to prevent degradation of the electrolytic capacitors within the inverter.
The packaging must be sealed to protect the inverter from moisture. Desiccants (such as silica gel) should be included within the packaging to maintain a relative humidity of less than 70%.
If the inverter is stored for over one year, the performance of the electrolytic capacitors may decline. At least once a year, connect the inverter to power and operate it for 30 to 60 minutes.
