What to do if data cannot be written/read from Inovance MD520 DC Drives?
If data cannot be written into or read from the Inovance DC Drives after a successful connection, verify the accuracy of the operated address. For instance, with I and Q addresses at 520-531, PZD1 and PZD2 data are stored in QW520 and QW522, respectively (use PQW for S7-300/S7-400 PLCs). When using SFC15, ensure RET_VAL is 0 to avoid invocation errors.
Why does Inovance MD520 DC Drives report ERR164 after communication is established?
If, after establishing communication with Inovance DC Drives, error ERR164 arises and cannot be cleared, ensure that the high-order 8 bits of the PZD1 data (QW data) written into the AC drive are set to 0 within the PLC program. If they are not 0, modify them accordingly.
What to do if PZD1 or PZD2 cannot be written/read in Inovance MD520 DC Drives?
If you're experiencing issues writing or reading PZD1 or PZD2 data on your Inovance DC Drives after a successful connection, make sure that F0-02 is set to 2 and F0-03 is set to 9. Also, check that the command reference falls between 1 and 7 (not bit), or the frequency reference is between –F0-10 and +F0-10. Finally, verify that FE-00 is set to U3-17 and FE-01 is set to U3-16; if not, correct manually or restore factory settings.
What to do if there is no display upon power-on of Inovance MD520 DC Drives?
If there is no display upon power-on with your Inovance DC Drive, first, check the power supply to ensure the drive is properly connected to the grid and the grid voltage is adequate. Next, verify the 24 V and 10 V output voltages on the control board to see if the switched-mode power supply (SMPS) is faulty. Also, ensure the control board is correctly connected to the driver board and operating panel by re-connecting the 8-pin and 40-pin flat cables. If problems persist, it may indicate damage to the pre-charge resistor.
What to do if Inovance MD520 earth leakage circuit breaker trips during operation?
If the earth leakage circuit breaker trips during operation, it might be due to poor anti-interference performance. Consider using an earth leakage circuit breaker from a recommended manufacturer. For a single AC drive, tighten the EMC screw. For multiple AC drives, disconnect the optional EMC grounding screw. You could also install a simple filter on the input side of the AC drive, wind the LN/RST cable on a ferrite core near the earth leakage circuit breaker, use an earth leakage circuit breaker with greater rated operating current, reduce the carrier frequency while ensuring performance, or use shorter motor cables.
Why does Inovance MD520 DC Drives earth leakage circuit breaker trip upon power-on?
If the earth leakage circuit breaker trips when you power on your Inovance DC Drives, it's likely due to poor anti-interference performance of the earth leakage circuit breaker. You can try the following: * Use an earth leakage circuit breaker from a recommended manufacturer. * Use an earth leakage circuit breaker with a greater rated operating current. * Move the unbalanced load to the front end of the earth leakage circuit breaker. * Remove the EMC screw or disconnect the grounding terminal of the external EMC filter to reduce the capacitance of the input end to the ground.
How to prevent high-speed pulse interference in Inovance MD520 control circuit?
To prevent high-speed pulse interference in your Inovance DC Drives control circuit, consider these steps: * Use a shielded twisted-pair cable and ground it at both ends. * Connect the motor enclosure to the PE terminal of the AC drive. * Connect the PE terminal of the AC drive to the PE terminal of the grid. * Add an equipotential bonding grounding wire between the host controller and the AC drive. * Separate the signal cable from the power cable by a distance of at least 30 cm. * Add a ferrite clamp to the signal cable, or wind the signal cable on a magnetic ring for one to two turns. * Wind the output U/V/W cables of the AC drive on a magnetic ring for two to four turns. * Use a shielded power cable and ensure that the shield is well- grounded.
What causes encoder feedback signal errors in Inovance MD520 DC Drives, and how can I fix it?
To address encoder feedback signal errors in Inovance DC Drives: * Route the encoder cable and power cable in different cable ducts. * When the AC drive is far away from the motor, disconnect the grounding (PE) terminal from the encoder shield on the AC drive side. * Add a magnetic ring or ferrite clamp for the encoder signal cable close to the AC drive. * Wind the output U/V/W cables of the AC drive on a magnetic ring for two to four turns. * Use a shielded power cable and ensure that the shield is well- grounded.
How to minimize common I/O signal interference in Inovance MD520 DC Drives?
To minimize common I/O signal interference in Inovance DC Drives, implement these measures: * Use shielded cables as the I/O signal cables, with the shield connected to the PE terminal. * Reliably connect the PE terminal of the motor to the PE terminal of the AC drive. * Connect the PE terminal of the AC drive to the PE terminal of the grid. * Add an equipotential bonding grounding wire between the host controller and the AC drive. * Wind the output U/V/W cables of the AC drive on a magnetic ring for two to four turns.
How to suppress leakage current in Inovance MD520?
To suppress leakage current in Inovance DC Drives, you can: * Increase the rated operating current of the circuit breaker. * Replace the circuit breaker with a new one with high-frequency suppression. * Reduce the carrier frequency. * Shorten the output drive cable. * Install a current leakage suppression device. * Use a circuit breaker from recommended manufacturers such as Chint Electric and Schneider.
