Overview
The Yaskawa VT545015-AM is a Varispeed P7 series AC variable frequency drive. The P7 was designed for variable torque applications like Fans and Centrifugal Pumps, supplied with V/f control and Normal Duty overload rating of 110% for one minute. This unit provides straightforward speed and torque control for motor applications in HVAC, irrigation, material handling, and general industrial pump systems. While a legacy product no longer promoted in the Americas, the P7 remains a proven, cost-effective solution for retrofit and replacement applications.
Key Features
- V/f (volts-per-frequency) control for stable torque delivery in fan and pump loads
- 110% Normal Duty overload rating for one minute, rated for continuous duty cycles
- Compact NEMA Type 1 (IP20) enclosure design
- Simple parameter set and commissioning for minimal integration effort
- Multi-voltage availability (208-240V and 480V 3-phase input)
- Wide horsepower range across P7 series (5–500 HP)
Technical Specifications
Verify compatibility and voltage/current ratings with your system integrator before ordering, as specific nameplate data for the VT545015-AM variant is not publicly available. Refer to the Yaskawa P7 family datasheet for model-to-spec cross-reference.
Typical Applications
- Centrifugal pump speed control (constant or variable load)
- Cooling tower and condenser fan drives
- HVAC supply and return fan modulation
- Irrigation and lift station pump applications
- Industrial blower and material handling conveyor systems
- Retrofit and upgrade of older fixed-frequency motor starters
Compatibility & Replacements
Compatible With
- 3-phase AC induction motors 5–500 HP
- Standard NEMA B and Design C motors
- 208–240 V and 480 V 3-phase utility power (50/60 Hz)
- Yaskawa digital operator panels (e.g., JVOP-160)
- Basic relay and analog control circuits
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The Yaskawa VT545015-AM may replace earlier or equivalent P7 CIMR-series model numbers in the same voltage/horsepower class. Exact cross-reference requires nameplate and specification sheet confirmation.
Works With
- Yaskawa Varispeed P7 digital and analog operators
- Standard industrial 3-phase contactor and motor starter circuits
- DC bus capacitor charging and soft-start logic (built-in)
- Basic voltage and frequency monitoring via onboard terminal block interface
