What to do if Omron OMNUC G5 Servo Drives show Immediate Stop Input Error?
If Omron Servo Drives show an Immediate Stop Input Error, it means an Immediate Stop (STOP) signal was entered. Check the Immediate Stop (STOP) signal wiring.
What to do if Omron Servo Drives are overloaded?
If you're encountering an overload with your Omron Servo Drives, it means the feedback value for torque command exceeds the overload level specified in the Overload Detection Level Setting (3512 hex). Check if torque (current) waveforms oscillate or excessively oscillate vertically during analog output or communications. Review the overload warning display and the load rate through communications. You can increase the capacities of the Servo Drive and the Servomotor, set longer acceleration and deceleration times, and reduce the load. Alternatively, try readjusting the gain.
What causes overvoltage in Omron Servo Drives?
An overvoltage in Omron Servo Drives occurs when the power supply voltage exceeds the allowable input voltage range. To address this, measure the voltage between the connector (L1, L2, and L3) lines and input the correct voltage. Remove the phase advance capacitor. Use a tester to measure the resistance of the external resistor between the B1 and B2 terminals on the Servo Drive; if the resistance is infinite, the wiring is broken, so replace the external resistor. You might also need to change the regeneration resistance and wattage to the specified values by calculating the regenerative energy and connecting an External Regeneration Resistor with the required regeneration absorption capacity and reducing the descent speed. If all else fails, replace the Servo Drive.
Why do Omron OMNUC G5 Servo Drives overheat?
If your Omron Servo Drives are overheating, it's because the temperature of the Servo Drive radiator or power elements exceeded the specified value. To resolve this, improve the ambient temperature and the cooling conditions of the Servo Drive. Also, consider increasing the capacities of the Servo Drive and the Servomotor, setting longer acceleration and deceleration times, and reducing the load.
Why Omron Servo Drives show main circuit power supply undervoltage?
If you're experiencing a main circuit power supply undervoltage with your Omron Servo Drives, it could be due to a momentary power interruption between L1 and L3 for longer than the value specified for the Momentary Hold Time (3509 hex), or the voltage between the positive and negative terminals in the main power supply converter dropped below the specified value while the servo was ON. Measure the voltage between the connector (L1, L2, and L3) lines. Increase the power supply voltage, or change the power supply. Eliminate the cause of the failure of the electromagnetic contactor on the main circuit power supply, and then turn ON the power again. Check the setting of the Momentary Hold Time (3509 hex). Set each phase of the power supply correctly. Increase the power supply capacity.
