EV510A-0037G/0055P-T4: Dual-Rated Design for Superior Performance & Reliability
The EV510A-0037G/0055P-T4 is a high-performance vector Variable Frequency Drive (VFD) engineered to meet the most diverse and demanding applications in industrial automation. The core advantage of this AC drive lies in its G/P Dual-Rated design, allowing a single unit to satisfy two distinct application profiles :
- G-Type (Constant Torque): Rated for 3.7kW (approx. 5 HP) “General” (G-type) loads, such as conveyors, machine tools, or crushers. These applications demand high starting torque and stable low-speed operation.
- P-Type (Variable Torque): Rated for 5.5kW (approx. 7.5 HP) “Pump or fans” (P-type) loads. These applications prioritize energy efficiency and smooth control of flow or airflow.
This dual capability makes the EV510A-0037G/0055P-T4 an ideal choice for OEM manufacturers and system integrators, simplifying inventory and standardizing the control platform across multiple applications.
As the upgraded version of the EV510 series, the EV510A features a “smaller in size, more compact in structure… and more stable in performance”. It employs an advanced “high-performance current vector control” algorithm, ensuring exceptional motor speed control accuracy. Critically, it integrates unique features designed to maximize production uptime, including “Instantaneous stop not stop” (ride-through) and a “Quick current-limit function”. These features make it not only powerful but exceptionally reliable, capable of handling grid fluctuations and sudden load impacts with ease.
Why Choose This 3.7kW(5HP) / 5.5kW(7.5HP) 380V Vector Control VFD?
Among the many AC drives on the market, the EV510A-0037G/0055P-T4 stands out with a unique combination of features that provide an exceptional value proposition.
- One VFD, Two Applications (Maximize Your ROI):The G/P Dual-Rated design is its most significant advantage. You no longer need to procure and stock two different VFDs for a 3.7kW machine tool and a 5.5kW fan. The EV510A-0037G/0055P-T4 handles both. This dramatically reduces your inventory costs, simplifies purchasing, and improves maintenance standardization.
- Designed for Maximum Uptime (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.
- Compact Design, Upgraded Performance (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”. 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).
- Powerful Control for Any Task (Versatile):Whether your application needs the high precision of FVC ($\pm$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’s the difference between G-Type and P-Type on the EV510A-0037G/0055P-T4?
A: This refers to the drive’s dual-rating, which you select via parameter P9-76. G-Type (General) is for 3.7kW Constant Torque loads (like conveyors) and provides higher overload capacity (150% for 60s). P-Type (Pump) is for 5.5kW Variable Torque loads (like fans/pumps) with a standard overload (120% for 60s).
Q: What is the difference between the EV510A and EV510?
A: The EV510A is the upgraded version of the EV510 series. The EV510A features a “smaller in size, more compact in structure, and more stable in performance”.
Q: How does the “Instantaneous stop not stop” function actually work?
A: When the VFD detects an instantaneous power loss or voltage sag, it immediately enters a special mode. It uses the feedback energy generated by the motor’s own inertia (regenerative energy) to “compensate for voltage-drop to keep running for a short time” until grid power returns.
Q: Can this VFD control two motors?
A: Yes, but not simultaneously. The EV510A has a “Multi-motor Switch” function. You can set up and store two different sets of motor parameters (in parameter groups P1 and A2) and switch between them using a digital input terminal (by setting a function in P4 group) or parameter P0-24.
Q: What are the most common fault codes for the EV510A?
A: Common VFD fault codes include FU02 (Over current during acceleration), FU06 (Overvoltage during deceleration), FU09 (Under voltage), and FU14 (Inverter Overheat). Please see the How-To guide below for detailed troubleshooting.
Q: Does the EV510A support PID control?
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: Quick Start – How to Perform Motor Auto-Tuning (Auto-Tune)
To achieve the best performance in Sensorless Vector Control (SVC) mode (when P0-01=0You must first perform a motor auto-tune.
- Input Motor Nameplate Data: In parameter group
P1Enter 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
P1-37to choose the tuning type:1: Asynchronous machine static self-learning2: Asynchronous machine dynamic complete self-learning (Requires motor to be uncoupled)3: Asynchronous machine static complete self-learning
- Execute Auto-Tune: After selecting the mode, press the RUN key to begin the auto-tuning process.
Guide 2: Advanced Application – How to Set Up PID Control (for Constant Pressure)
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
AI2jumper on the control board to ‘I’ (current). Then, set the parameterPA-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 inPA-01(e.g.,50.0%). - Adjust PID Gains:
PA-05(Proportional Gain Kp1): Default is20.0. Adjust to speed up or slow down the response.PA-06(Integral Time Ti1): Default is2.00s. 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 a faultFU31(PID feedback lost).
