EV510A-0750G/0900P-T4: High-Power Dual-Rated Drive for Uptime and Efficiency
The EV510A-0750G/0900P-T4 is a high-performance vector Variable Frequency Drive (VFD) built for demanding, high-power industrial tasks. The defining feature 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 :
- G-Type (Constant Torque): Rated for 75kW (approx. 100 HP) “General” (G-type) loads, such as large compressors, extruders, or heavy-duty conveyors. This mode is defined by its high starting torque and robust overload capacity.
- P-Type (Variable Torque): Rated for 90kW (approx. 125 HP) “Pump or fans” (P-type) loads. This mode is optimized for energy efficiency in applications like centrifugal pumps and large-scale ventilation.
This strategic dual-rating simplifies 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.
Why Choose the EV510A-0750G/0900P-T4?
In the high-power class, the EV510A-0750G/0900P-T4 provides a unique combination of power, intelligence, and reliability.
- Maximize Operational Flexibility (Dual-Rated):
The G/P Dual-Rated design is its most significant advantage. You no longer need to procure and stock two different VFDs for a 75kW heavy-duty application and a 90kW fan. The EV510A-0750G/0900P-T4 handles both. This dramatically reduces your inventory costs, simplifies purchasing, and improves maintenance standardization. - Engineered for Continuous Operation (Extreme Reliability):
In continuous production, downtime is costly. The EV510A’s “Instantaneous stop not stop” function provides invaluable “ride-through” capability during unstable grid conditions, while the “Quick Current-limit” actively prevents trips from load shocks. Choosing the EV510A is choosing uninterrupted productivity. - A Modern, Compact Powerhouse (Save Space & Cost):
As the upgraded version of the EV510, the EV510A is “smaller in size, more compact in structure, and more stable in performance”.1 It not only saves valuable electrical cabinet space but also implies a lower failure rate and longer service life, reducing your Total Cost of Ownership (TCO). - A Comprehensive Control Platform (Versatile):
Whether your application needs the high precision of FVC (±0.02% steady speed precision) or the powerful low-speed torque of SVC (150% starting torque at 0.5Hz) , the EV510A delivers. Combined with its rich I/O and “Built-in PID” , it is a motor controller that can handle nearly any mid-level automation task.

Frequently Asked Questions (FAQ)
Q: What do G-Type and P-Type mean on the EV510A-0750G/0900P-T4? A: This specifies the drive’s dual-rating, selectable via parameter P9-76. G-Type (General) is rated for 75kW Constant Torque applications (like extruders) and provides a high overload capacity (150% for 60s). P-Type (Pump) is rated for 90kW Variable Torque applications (like fans) with a standard overload (120% for 60s).
Q: Is the EV510A different 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 run 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 (Over voltage during deceleration), FU09 (Under voltage), and FU14 (Inverter Overheat).
Q: Does this drive have a 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 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.
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.
- Input Motor Nameplate Data: In parameter group P1, enter the following values from your motor’s nameplate:
- 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:
- 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.
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.
- 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).
- 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%).
- Adjust PID Gains:
- PA-05 (Proportional Gain Kp1): Default is 20.0. Adjust to speed up or slow down the response.
- PA-06 (Integral Time Ti1): Default is 2.00s. Adjust to eliminate steady-state error.
- Set Feedback Loss Detection: To prevent the pump from running at max speed if the sensor wire breaks, set PID feedback loss detection.
- 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).
