CIMR-V7AM40P4

The Yaskawa CIMR-V7AM40P4 is classified as a Variable Frequency Drive equipped with an integrated digital operator for convenient management. This model requires a 3-phase power supply operating within a range of 380 to 460 VAC at 50 or 60 Hz. The output voltage reflects the input voltage, allowing for optimal compatibility across its intended applications.

Prominent features of this VFD include a programmable maximum output frequency of up to 400 Hz, making it suitable for demanding speed control requirements. Rated for a motor power of 0.75 HP in a 460 V setup, the device ensures reliable efficiency.

Flexibility is built into the system with selectable control modes, allowing users to choose between V/f and Open Loop Vector control. Its frequency adjustment range spans from 0.1 Hz to 400 Hz, providing the capability to finely tune application parameters. The overload tolerance supports up to 150% of rated current for a duration of 60 seconds, accommodating temporary surges.

For precision applications, frequency stability measurements indicate ±0.01% accuracy in digital settings over a temperature scope from -10°C to +50°C, while analog stability remains within ±0.5% accuracy between 15°C and 35°C. Speed control is reliable, achieving ±0.5% to ±1% precision with V/f control and ±0.2% when using vector control, including slip compensation for enhanced performance.

Ramp time can be customized from 0.01 to 6000 seconds, with separate programming options for acceleration and deceleration phases. This drive supports diverse signal reference inputs, like 0–10 VDC, 4–20 mA, and digital potentiometer connections, offering adaptability to various signal sources. Notably, it functions within an input voltage tolerance of -15% to +10% of the nominal voltage, ensuring operational flexibility in varying electrical environments.
