Working Principle:
The drive rectifies 3-phase AC input to DC via a diode bridge, filters it through the DC bus capacitor and choke, then inverts it back to variable-frequency 3-phase AC using IGBT power switches. The control algorithm modulates PWM duty cycle and frequency to control motor speed and torque. Sensorless vector control estimates rotor flux from voltage and current measurements, enabling high-performance operation without an encoder.

Key Advantages:

• Integrated EMC filter eliminates need for external line reactor
• Sensorless vector delivers 150% torque at zero speed — no encoder needed
• Ethernet/IP native — no adapter card required
• Front-accessible terminals reduce wiring time by 50%

Applicable Industries: Pumps, fans, compressors, conveyors, mixers, material handling, HVAC, water/wastewater

Installation Requirements:

• Mount vertically with 100 mm clearance above and below
• Use 4 AWG to 8 AWG copper conductors (NEC Table 310.16)
