Why do Omron R88D-KN01H-ECT-R 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.
How to fix Error Counter Overflow in Omron R88D-KN01H-ECT-R Servo Drives?
To fix an Error Counter Overflow in Omron Servo Drives, the issue arises when position error pulses exceed the Following error window setting. This can occur if motor operation doesn't follow the command or if the Following error window value is too small. Begin by checking if the Servomotor rotates according to the position command pulse. Examine the torque monitor for saturated output torque and adjust the gain accordingly. Maximize the set values on the Positive and Negative torque limit values. Ensure the encoder is wired correctly. Lengthen the acceleration and deceleration times, and reduce the load and speed. If necessary, increase the set value of object 6065 hex.
Why Omron R88D-KN01H-ECT-R Servo Drives show Regeneration Overload?
Omron Servo Drives may show a Regeneration Overload if the regenerative energy exceeds the processing capacity of the Regeneration Resistor. This can occur due to high regenerative energy during deceleration from a large load inertia, high Servomotor rotation speed, or the external resistor's operating limit being restricted to a 10% duty. Check the load rate of the Regeneration Resistor through communications. Increase the capacities of the Servo Drive and the Servomotor, and lengthen the deceleration time. Use an External Regeneration Resistor. Set the Regeneration Resistor Selection to 2.
Why Omron R88D-KN01H-ECT-R Servo Drives show Servo Drive Overheat?
Omron Servo Drives may overheat if the temperature of the Servo Drive radiator or power elements exceeds the specified value. This can be caused by a high ambient temperature around the Servo Drive or an overload condition. To resolve this, improve the ambient temperature and cooling conditions of the Servo Drive. Additionally, consider increasing the capacities of the Servo Drive and the Servomotor, setting longer acceleration and deceleration times, and reducing the load.
Why Omron R88D-KN01H-ECT-R Servo Drives show Encoder Communications Error?
Omron Servo Drives may display an Encoder Communications Error due to a data error, primarily caused by noise. This can occur even if the encoder cable is connected. To address this, ensure the encoder power supply voltage is within the required 5 VDC ±5% range, especially if the encoder cable is long. Separate the Servomotor cable and the encoder cable if they are bundled together. Connect the shield to FG.
What causes encoder communication disconnection error in Omron Servo Drives?
If you encounter an encoder communications disconnection error with Omron Servo Drives, it means a disconnection was detected because communications between the encoder and the Servo Drive were stopped more frequently than the specified value. To resolve this, wire the encoder correctly as shown in the wiring diagram and correct the connector pin connections.
How to fix encoder communication error in Omron R88D-KN01H-ECT-R Servo Drives?
If you're experiencing an encoder communications error with your Omron Servo Drives, it's likely due to noise affecting the data from the encoder. To fix this, provide the required encoder power supply voltage 5 VDC ±5% (4.75 to 5.25 V), paying special attention when the encoder cable is long. If the Servomotor cable and the encoder cable are bundled together, separate them. Also, connect the shield to FG.
What does excessive hybrid deviation error mean for Omron R88D-KN01H-ECT-R Servo Drives?
If you're getting an excessive hybrid deviation error on your Omron Servo Drives, it means that during fully-closed control, the difference between the load position from the external encoder and the Servomotor position from the encoder was larger than the number of pulses set as the Hybrid Following Error Counter Overflow Level (3328 hex). Check the Servomotor and load connection. Check the external encoder and Servo Drive connection. When moving the load, check to see if the change in the Servomotor position (encoder feedback value) has the same sign as the change in the load position (external encoder feedback value).
What to do if Omron R88D-KN01H-ECT-R 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 Overspeed in Omron R88D-KN01H-ECT-R Servo Drives?
Overspeed in Omron Servo Drives occurs when the Servomotor rotation speed exceeds the value set on the Overspeed Detection Level Setting. This can be due to excessive speed commands, incorrect input frequency, dividing ratio, or multiplication ratio of the command pulse. If overshooting occurs due to faulty gain adjustment, adjust the gain. Ensure the encoder is wired correctly.
