Yaskawa E1000 Inverter

Optimized Energy Efficiency

One of the most outstanding strengths of the E1000 is its exceptional energy-saving capability.

When combining variable frequency control with the energy-saving mode, energy savings can reach 20–26% at medium loads of 50–60%.

In particular, when using high-efficiency IPM or SPM permanent magnet motors, operational efficiency can increase by an additional 5–7% compared to standard motors, achieving a total efficiency of over 87%.

Experimental data in the catalogue shows that with the Yaskawa E1000 inverter:

At light loads, energy savings increase significantly.

In compressor applications, the E1000 helps reduce pressure fluctuations, minimize idle running time, and cut losses caused by over-run.

Yaskawa E1000 inverter supports multiple control methods to suit different load types:

• Traditional V/f control.
• Sensorless vector control for induction motors.
• Optimized control for IPM/SPM motors to achieve maximum efficiency.
• Notable Technical Features:
• Searching Drive & Optimum Efficiency: Automatically finds the optimal frequency and voltage to reduce power consumption.
• Anti-Vibration Control: Detects and suppresses vibration within a specified frequency range.
• Multi-Speed Control & Inching Operation: Allows multiple preset speeds and precise jog (inching) control.
• Stopping Modes: Free-run (coast to stop) or decelerated stop according to a set ramp time.
• USB Support with Copy Unit (optional): Enables quick duplication of drive configurations.

The E1000 is designed with flexibility, offering multiple connection and expansion options:

Standard LED operator and optional LCD operator with clear, easy-to-read display.

Multifunctional inputs/outputs: Analog (0–10V, 4–20mA), pulse, relay, and digital I/O.

Supports optional communication cards for industrial networks such as Modbus, BACnet, Profibus, and LonWorks.

Can be connected to a DC reactor to reduce harmonics.

The E1000 complies with RoHS standards, ensuring safety and environmental friendliness. Its internal design includes:

• Control circuitry isolated from the power circuitry.
• Replaceable cooling fan to extend equipment lifespan.
• Fault relay output for easy integration into system protection circuits.
• Built-in EMI filter to reduce electromagnetic interference.
• Conveniently positioned grounding terminals for safe wiring.
