EV510A-2200G/2500P-T4: A High-Capacity VFD for Power, Precision, and Reliability
The EV510A-2200G/2500P-T4 is a high-performance vector Variable Frequency Drive (VFD) engineered to meet diverse and demanding applications in industrial automation. The defining advantage of this AC drive is its G/P Dual-Rated capability, which allows a single unit to be expertly configured for two different operational modes :  Â
- G-Type (Constant Torque): Rated for 220kW (approx. 300 HP) “General” (G-type) loads, such as plastic extruders, rock crushers, or heavy-duty conveyors. This mode is defined by its high starting torque and robust overload capacity.  Â
- P-Type (Variable Torque): Rated for 250kW (approx. 350 HP) “Pump or fans” (P-type) loads. This mode is optimized for energy efficiency in applications like centrifugal pumps and large-scale ventilation.  Â
This intelligent dual-rating streamlines inventory for system integrators and provides a standardized, high-performance control platform. As an enhanced version of the EV510 series, the EV510A is “smaller in size, more compact in structure… and more stable in performance”. It utilizes a “high-performance current vector control” algorithm for outstanding precision and integrates essential reliability features like “Instantaneous stop not stop” (power loss ride-through) and a “Quick current-limit function” to maximize system uptime.  Â
Why Choose the EV510A-2200G/2500P-T4?
In the 220-250kW power class, the EV510A-2200G/2500P-T4 provides an intelligent combination of power, precision, and value.
- Strategic Power Flexibility (Dual-Rated): The G/P dual-rating is this drive’s most intelligent feature. It eliminates the need to source and stock two separate AC drives for a 220kW heavy-duty machine and a 250kW fan. The EV510A-2200G/2500P-T4 handles both, reducing inventory costs and simplifying procurement.  Â
- Engineered for Extreme Uptime: For critical processes, reliability is paramount. The “Instantaneous stop not stop” function provides essential ride-through for brief power sags, while the “Quick Current-limit”  actively prevents nuisance trips from load shocks, keeping your operation running.  Â
- A Compact High-Power Solution: As the upgraded EV510A version, this drive is “smaller in size, more compact in structure, and more stable in performance”. This saves valuable cabinet real estate and contributes to a lower Total Cost of Ownership (TCO) through enhanced reliability.  Â
- Integrated Intelligence: This is more than a simple motor spinner. With powerful Sensorless Vector Control (SVC)  for high-torque tasks and a “Built-in PID” controller for process loops, this single drive can manage a wide range of sophisticated automation tasks without needing an external PLC.Â

Frequently Asked Questions (FAQ)
Q: What is the G/P Dual-Rating on the EV510A-2200G/2500P-T4?
A: This specifies the drive’s dual-rating, selectable via parameter P9-76. G-Type (General) is rated for 220kW Constant Torque applications (like extruders) and provides a high overload capacity (150% for 60s). P-Type (Pump) is rated for 250kW Variable Torque applications (like fans) with a standard overload (120% for 60s).
Q: Is the EV510A an upgrade from the EV510?
A: Yes, the EV510A is the upgraded version. It is “smaller in size, more compact in structure, and more stable in performance”.
Q: What is “Instantaneous stop not stop”?
A: This is a power loss ride-through function. If the power sags, the drive uses the motor’s feedback energy to “compensate for voltage-drop to keep running for a short time,” preventing a shutdown.
Q: Can this VFD control two different motors?
A: Yes, but not simultaneously. It has a “Multi-motor Switch” function. You can program two motor profiles (in parameter groups P1 and A2) and switch between them using a digital input or parameter P0-24.
Q: What are the most common fault codes?
A: Common VFD fault codes include FU02 (Over current during acceleration), FU06 (Overvoltage during deceleration), FU09 (Under voltage), and FU14 (Inverter Overheat).
Q: Does this drive have a built-in PID controller?
A: Yes, it features a powerful “Built-in PID” controller. This allows it to receive an analog feedback signal (like a pressure or temperature sensor) and automatically manage a closed-loop process. The parameters are in a group PA.
Quick Start Guide (How-To)
This guide is intended to help you quickly set up and diagnose the EV510A Variable Frequency Drive based on the user manual.  Â
Guide 1: Commissioning – How to Auto-Tune the Motor
To achieve the best performance in Sensorless Vector Control (SVC) mode (when P0-01=0), you must first perform a motor auto-tune.  Â
- Input Motor Nameplate Data: In parameter group P1, enter the following values from your motor’s nameplate:  Â
- P1-01: Motor 1 Rated power (kW)
- P1-02: Motor 1 Rated voltage (V)
- P1-03: Motor 1 Rated current (A)
- P1-04: Motor 1 Rated frequency (Hz)
- P1-05: Motor 1 Rated speed (rpm)
- Select Auto-Tune Mode: Set parameter P1-37  to choose the tuning type:  Â
- 1: Asynchronous machine static self-learning
- 2: Asynchronous machine dynamic complete self-learning (Requires motor to be uncoupled)
- Execute Auto-Tune: After selecting the mode, press the RUN key to begin the auto-tuning process.  Â
Guide 2: Process Control – How to Set Up PID
Using the built-in PID (Group PA)  allows you to create a constant pressure pump system without an external PLC.  Â
- Set PID Feedback Source: Wire your 4-20mA pressure transducer to analog input AI2. Set the AI2 jumper on the control board to ‘I’ (current). Then, set parameter PA-02 = 1 (PID feedback source = AI2).  Â
- Set PID Target Value (Setpoint): Set PA-00 = 0 (PID reference source = PA-01). Then, enter your target pressure percentage in PA-01 (e.g., 50.0%).  Â
- Adjust PID Gains:
- PA-05 (Proportional Gain Kp1): Default is 20.0. Adjust to speed up or slow down the response.  Â
- PA-06 (Integral Time Ti1): Default is 2.00s. Adjust to eliminate steady-state error.  Â
- Set Feedback Loss Detection: To prevent the pump from running at max speed if the sensor wire breaks, set PID feedback loss detection.  Â
- PA-26: Set detection level (e.g., 10.0%).
- PA-27: Set detection time (e.g., 2.0s). This will trigger fault FU31 (PID feedback lost).Â
