Advantages of Micctech VFDs are mainly in these sides:
1. Micctech VFD Suit for most of Asynchoronaus and synchoronause drive and support kinds of control method. For example:
Asynchoronous drive can choose No PG flux vector control, with PG flux vector control and V/F control;
For synchoronous drive, it can choose No PG flux vector control, with PG flux vector control.
2. Compatible encoder:
It support rotary transformer and ABZ incremental encoder.
3. Communication:
Modbus, CANopen and Profibus-DP.
4. Steady and reliable:
Micctech uses high-class electronic units, excellent design, conformal coating on PCBA and independent air flue, all them work together to ensure the VFD has longer life time.
5. High starting torque:
In No PG flux vector control mode, when output frequency is 0.25Hz, VFD can reach 150% rated torque; In PG flux vector control mode, when output frequency is 0Hz, VFD can reach 180% rated torque.
6. High torque precision:
In No PG flux vector control mode, torque control precision is less than 7.5%; In PG flux vector control mode, torque control precision is less than 5%.
7. Compact structure:
Book style structure saves room for whole electric cabnet. More VFDs can be installed in the same width cabinet.
