Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
Regulating motor speed and torque with exceptional precision in demanding automation environments, the Delta Electronics VFD055CB43A-20 variable frequency drive delivers advanced vector control capabilities within a compact, cost-effective form factor. Designed as part of the C200 Series, this drive features an integrated 5,000-step PLC, allowing for smart decentralized control without the overhead of additional hardware. Its multi-mode control capability, support for permanent magnet motors, and robust thermal engineering make it an ideal choice for high-reliability systems operating on 460V three-phase systems.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Delta Electronics |
| Model Number | VFD055CB43A-20 |
| Series Name | C200 Series |
| Applicable Motor Capacity | 5.5 kW (7.5 HP) |
| Input Voltage / Phase | 460 V (Three-Phase) |
| Input Rated Current | 17 A |
| Control Methods | V/F, SVC, V/F+PG, FOC+PG |
| Torque Limit (Max) | 200% torque current |
| Output Frequency Range | Normal: 0.00 to 600.00 Hz | Heavy Duty: 0.00 to 300.00 Hz |
| IP Protection Rating | IP20 / UL Open Type |
| Mounting Type | Wall Mount (A-Type) |
| Net Weight | 1.5 kg |
| Shipping Weight (Calculated) | 3.0 kg |
The C200 Series represents a significant technical evolution over legacy VFD-M and VFD-E drives. While mounting footprints may differ, parameters can generally be mapped directly via Delta's software tools. Ensure that control schemes utilizing legacy V/F curves are updated to take advantage of the advanced sensorless vector control algorithm for superior performance under low-speed, high-torque conditions.
As an IP20 open-type drive, this unit must be housed within a clean, climate-controlled industrial enclosure. If operating in high ambient temperatures near 50 degC, or when configuring high PWM carrier frequencies to reduce motor whine, output current de-rating curves must be strictly applied to avoid sudden overtemperature (oH) fault conditions.
When utilizing closed-loop PG feedback control (FOC+PG), use double-shielded twisted pair cables for encoder wiring. Keep the signal cable separate from the 460V power lines to mitigate electromagnetic noise injection. To prevent overvoltage (ov) trips during rapid deceleration of heavy loads, integrate a correctly sized dynamic braking resistor between terminals +1/DC+ and PB.
