FAQ
1.Does the VFD300CP43B-21 motherboard have a PCB anti-corrosion coating?
The The motherboard is equipped with a PCB anti-corrosion coating, which can prevent moisture, dust and minor corrosion.
2.What are the overall dimensions of the VFD300CP43B-21?
Supported. The The built-in PLC program capacity is 10,000 steps (10K Steps), and it is equipped with an RTC (Real-Time Clock) for a perpetual calendar function.
3.Does the VFD300CP43B-21 have a built-in braking chopper?
The Built-in braking chopper. Energy consumption braking can only be achieved by connecting an external braking resistor.
4.How many motors can the VFD300CP43B-21 multi-pump control function drive at most?
The
- The multi-pump control function can support up to 8 motors for coordinated control. If complete control of 8 pumps is required, a relay expansion card needs to be selected.
- Additional clarification: The quantitative circulation mode can accommodate up to 4 pumps (1 variable frequency + multiple constant frequency);
- The timed rotation mode can support up to 8 pumps.
