EV3000-4T0110G is a modular structure. The detachable operation keyboard is also supported, along with LED simple keyboard/LCD Chinese-English keyboard. It also supports parameter copying, uploading and downloading. Is the cabinet wall-mounted installation; The G type is a heavy-duty model, suitable for impact loads. It comes with PG encoder interface, can be directly connected to the incremental encoder to do closed-loop vector.
The Emerson EV3000-4T0110G has built-in motor self-learning capabilities for static/rotational tuning, automatically identifying motor parameters, and is essential for closed-loop vector control. Zero-speed servo locking: maintains torque at zero speed, preventing vehicle sliding during lifting. It also allows for online switching between speed and torque, and can switch control modes during operation. It is a simple PLC with multi-speed operation, capable of running at up to 10 speed logic segments. It is equipped with a PID regulator for constant voltage and constant flow closed-loop process control, mainly providing comprehensive protection against 28 faults including overcurrent, overvoltage, undervoltage, overheating, ground fault, and output short circuit.
Our Yueyang Tongtu E-commerce Co., Ltd. can offer you a complete package of services for these products. We also attach great importance to service experience, ranging from selection guidance, technical consultation to troubleshooting. For models that have been discontinued in the market, we can provide alternative solutions. Welcome to purchase.
Freight transportation advantages and container loading procedures
Moisture-proof and shockproof: the inner layer of the inverter is wrapped in thick anti-static plastic bags, and the high-density PE foam forming buffer block is covered.
Fumigation-free reinforced wooden crates: For some models, we will use fumigation-free composite wooden crates that meet international transportation standards for outer packaging. The joints of the crates will be reinforced with steel bars to effectively prevent deformation due to compression during transportation.
Yes. The EV3000-4T0110G integrates an AVR (Automatic Voltage Regulation) function and a power outage without stopping maintenance logic. When the input power grid fluctuates within the range of -15% to +10%, the frequency converter can automatically maintain a stable output voltage.
Mechanical jamming or excessive load: Check if the motor bearing or transmission belt is too resistant. Disconnect the motor from the mechanical connection and run it unloaded.
The acceleration time is set too short: The torque required by the motor is too large at the moment of startup. Please appropriately increase the parameters in the operation panel.
Output line insulation decline: Use a megohmmeter (megohmmeter) to measure the interphase resistance of the cable between the frequency converter and the motor and the insulation to ground, and check for any damage or moisture short circuit.
1. Constant pressure water supply and variable frequency energy-saving control for medium-sized industrial pumps and cooling tower fans.
2. Frequency conversion retrofit for screw air compressors, adjusting the intake pressure in real time according to the gas consumption.
3. Long-distance belt conveyors in mines and building material production lines, providing stable starting torque.
4. Driving of auxiliary oil pumps for edge sealing machines and injection molding machines, enabling rapid speed switching.
