What to do if Emotron Inverter displays 'Over speed'?
If the Emotron Inverter displays 'Over speed', it indicates that the motor speed measurement has exceeded the maximum level. To solve this, check the encoder cables, wiring, and setup, verify the motor data setup [22x], and perform a short ID-run.
How to troubleshoot 'Motor I2t' error on Emotron Inverter?
The 'Motor I2t' error on your Emotron Inverter indicates that the I2t value has been exceeded, meaning the motor is overloaded according to the programmed I2t settings. To address this: * Check for mechanical overload on the motor or machinery (bearings, gearboxes, chains, belts, etc.). * Change the Motor I2t Current setting.
Why does my Emotron Inverter show 'Locked rotor'?
If your Emotron Inverter displays 'Locked rotor', it means the torque limit has been reached while the motor is at standstill. This is likely due to a mechanical blockage of the rotor. Check for mechanical issues at the motor or connected machinery. You can also set the locked rotor alarm to OFF.
How to resolve 'Over volt (Mains)' error on Emotron Inverter?
If the Emotron Inverter displays 'Over volt (Mains)', it indicates that the DC Link voltage is too high due to an excessive mains voltage. To fix this, check the main supply voltage and try using alternative main supply lines to avoid interference.
What does 'Motor lost' mean on my Emotron Inverter?
If the Emotron Inverter displays 'Motor lost', it indicates a phase loss or significant imbalance on the motor phases. To resolve this: * Check the motor voltage on all phases. * Check for loose or poor motor cable connections. If the connections are okay, contact your supplier or set the motor lost alarm to OFF.
How to fix 'Over volt D(eceleration)' on Emotron Inverter?
If your Emotron Inverter shows 'Over volt D(eceleration)', it means the DC Link voltage is too high. This is often due to: * Too short deceleration time. * Too small brake resistor or a malfunctioning brake chopper. To resolve this, increase the deceleration time and check the dimensions and functionality of the brake resistor and brake chopper, if one is used.
What causes 'Under voltage' on my Emotron Inverter?
If the Emotron Inverter displays 'Under voltage', it signifies a low DC Link voltage. This can happen because of: * Too low or no supply voltage. * Mains voltage dip due to starting other major power-consuming machines on the same line. To address this, ensure all three phases are properly connected and tightened, verify the mains supply voltage is within the VSD's limits, and consider using other mains supply lines or activating the low voltage override function [421].
Why is my Emotron Inverter showing 'Over temp'?
If your Emotron Inverter displays 'Over temp', it indicates that the heatsink temperature is too high. This can be due to: * High ambient temperature. * Insufficient cooling. * Excessive current. * Blocked or stuffed fans. To fix this, check the VSD cabinet's cooling, ensure the fans are working correctly, verify the VSD and motor ratings, and clean the fans.
