Overview
Powerful overload capability: Able to withstand up to 180% overload within 60 seconds, ensuring stable operation of the system during heavy load startup or sudden load changes.
High-precision control performance: Using advanced vector control technology, a wide speed adjustment range (up to 1:50) and high speed stabilization accuracy (±0.5%) can be achieved even without a speed sensor.
Rich built-in functions: It comes standard with a PID controller, built-in braking chopper (DC braking can be achieved without an additional braking unit) and S-curve generator, etc., making it easy to integrate into various automation control systems.
Flexible communication and expansion: Provides a variety of optional communication interface modules to support connection with mainstream industrial field buses (such as PROFIBUS-DP, CANopen, DeviceNet, etc.) to facilitate system integration.
FAQ:
1.Lenze E82EV152K4C code LU appears, how to solve it?
Lenze E82EV152K4C reports LU (undervoltage) fault, follow the following simplified steps to solve it:
- Measure the three-phase input voltage (320-440V required), install a voltage regulator if the fluctuation is large, and tighten/replace loose and corroded terminal blocks.
- Replace power supply cables that are too small or too long to reduce line voltage drop.
- Professionals will check the internal rectifier bridge and filter capacitor (replace if there is any leakage), and calibrate the voltage detection circuit.
- Set parameter H03 to 1 for initialization, re-enter the motor parameters, and extend the acceleration time to reduce voltage fluctuations.
2.What should I do if Lenze E82EV152K4C reports OC failure?
The OC code of Lenze E82EV152K4C is an over-current fault. Different sub-codes correspond to different scenarios. Check and solve in order from outside to inside. The steps are simplified as follows:
- Check the machine and load: manually turn the motor shaft to eliminate mechanical jamming problems such as jamming and abnormal noise; if no OC error is reported during no-load operation, the load is too heavy or has a sudden change, and the load needs to be reduced or the working conditions need to be optimized.
- Check the circuit and motor: Check whether the U/V/W motor cable is damaged and whether the terminal is loose. If it is damaged, replace it and if it is loose, tighten it. Use a multimeter to measure the three-phase winding resistance of the motor. If the deviation exceeds 5% or the insulation resistance to ground is less than 1MΩ, the motor needs to be repaired or replaced.
- Adjust parameters to eliminate error reports: If errors are reported frequently during acceleration and deceleration, extend the acceleration time; if the current limit parameter is too low, adjust the matching parameters according to the motor nameplate; if the parameters are confusing, restore the factory settings and reconfigure.
- Check the internal hardware: After powering off and discharging, use a multimeter to test the IGBT module. If both forward and reverse conductivity is present, it is damaged and needs to be replaced. If the current is normal and still reports OC, it is most likely that the detection circuit such as the Hall sensor is faulty. It is recommended that professionals repair and replace components.
- For follow-up support: clean the dust on the drive radiator and check whether the cooling fan is operating normally to avoid overheating of components triggering over-current protection; if the problem still cannot be solved, contact Lenz official after-sales service to repair core components.
