Equipped with advanced vector control on the universal frequency converter

Suitable for high-precision positioning control

	PG vector control

	Suitable for applications that require high-precision positioning control, such as offset printing machines.

Improved the unique dynamic torque vector control performance of our company

Dynamic torque vectoring control is an advanced technology unique to our company. In dynamic torque vector control, the voltage error of the motor main circuit device is fully considered, and motor constant tuning and new magnetic flux monitoring are equipped, so that even at low speeds of 0.3Hz, a high starting torque of 200% can be achieved.

Compared with our previous products, by extending the rated time of overload, we have achieved the maximum amount of acceleration and deceleration functions in a short period of time, thereby improving the efficiency of cutting and handling machinery.
Overload tolerance: 200% -3 seconds/150% -1 minute

There are two specifications for standard products.

Difference in specifications	overload	Main purpose
HD (High Duty) specifications	200% -3 seconds/150% -1 minute	Used for heavy loads
LD (Low Duty) specifications	120% -1 point	Used for light loads

Built in braking circuit as standard in models below 22kW, suitable for up and down handling devices with more regenerative load applications.
When the power is below 7.5kW, a brake resistor is also built-in
If you want to further increase the power, you can order and produce models with 400V: 30kW~110kW.

Maximize the performance of universal motors

	sensorless vector control

	Suitable for high starting torque applications such as hanging basket style three-dimensional parking garages.

Advanced torque response has been achieved to cope with rapid load changes. By controlling the magnetic flux, the variation of motor speed is kept within the minimum range, thereby controlling the vibration. Suitable for equipment such as cutting machinery that requires stable rotational speed.

Further improved the response to previously highly rated operation command terminals, achieving shorter response times.
Shortened the interval time between each cycle, suitable for operational purposes with a high degree of repetitive operation.

Widely used

Make the pulse train input function a standard configuration

Speed control commands can be issued by using input pulse trains (single-phase pulses+command symbols) such as pulse generators.
(Maximum pulse input 100kHz)

Configure ratio operation

This function is suitable for adjusting several conveyor systems. Compared to the main speed, the frequency command ratio of several driven axes can be set. It is easy to adjust the handling speed of a conveyor with load changes.

By monitoring the action of the braking transistor, the braking resistor can be protected. Output a dedicated signal when abnormal brake transistor is detected. By using these signals, the protection function can be activated by setting the circuit that cuts off the input power outside the frequency converter.

The accuracy of the braking signal has been improved during the process of up and down transportation. By adding the torque value to the current value and frequency monitored during the output of the braking signal, the braking timing can be easily adjusted.

Swing control function suitable for winding control

Compare the target value and feedback value, and add or subtract the PID operation result from the reference speed. Because the gain (proportional band) of the PID calculation part can be set low (wide), it can be applied to automatic control systems that require fast response, such as speed control.

(1) Analog input: has 2 voltage inputs (with polarity) and 1 current input (2)
Low water volume stop function (when the water volume is low, it can be pressurized before stopping) (3) Line V/f mode with 3 points (4) Simulated fault output function (5) Can be selected to the 4th motor (6) S-shaped acceleration and deceleration range setting (7) PID feedback disconnection detection

environmental performance

Compared with previous frequency converters, MEGA has improved environmental performance.

	(1) Strengthen the environmental resistance of cooling fans
	(2) Copper bars are plated with nickel and zinc

Compared with previous models, MEGA has enhanced its adaptability to the environment. However, when using it in the following situations, it is still necessary to pay attention to the usage environment.

a.	Environments that produce sulfurized gases (tire manufacturing, paper industry, wastewater treatment, fiber industry)
b.	Environments that generate conductive dust and foreign objects (such as metal processing, extruders, printing machines, garbage disposal, etc.)
c.	Other: When used outside of standard environmental specifications

If you need to use it under the above conditions, our company has reinforced products available. Please consult our sales department.

■ Basic connection diagram

＊1	There is wiring protection on the input side (primary side) of the frequency converter, therefore, please install the recommended wiring circuit breaker (MCCB) or residual current circuit breaker (ELCB) (with overcurrent protection function) for each frequency converter. Do not use circuit breakers with recommended power or higher.
＊2	MCCB or ELCB are used when separating the frequency converter from another power source, therefore, recommended electromagnetic contactors (MCs) should be installed on each frequency converter as needed. In addition, when placing MC or solenoid coils near the frequency converter, please connect them in parallel with the surge absorber.
＊3	Even if the main power supply of the frequency converter is cut off, if you want to maintain the overall alarm signal when the protection function is working together, or if you want the operation panel to display, please connect this terminal to the power supply.
