FAQ 

1.Does the VFD300C43A-21 cooling fan have a lifespan warning function?

The It has the functions of real-time timing and life warning reminder:

2.What is the maximum rated power of the three-phase motor that the VFD300C43A-21 can be matched with?

Supported. The

• Compatible with 380~480V three-phase asynchronous and permanent magnet synchronous motors.
• Rated output current under heavy-load conditions is 60A, capable of stably driving a 30kW constant-torque load; in light-load scenarios of fans and water pumps, it can be matched with corresponding 30kW variable-torque motors.

3.What are the length, width and depth dimensions of the VFD300C43A-21 complete machine in millimeters?

The

• VFD300C43A-21 is a C-frame model. The overall dimensions of the machine (width × height × depth, in mm):
• 250 × 400 × 210
• The net weight of the machine is 10.6 kg.

4.What is the output ratio of zero-hertz torque for the VFD300C43A-21 when paired with the PG encoder for closed-loop control?

The

• When using FOC with PG encoder closed-loop control, 0Hz can stably output 150% of the rated torque.
• In the open-loop vector mode of the non-inductive SVC, 0.5Hz outputs 150% of the rated torque.
