Today, I successfully powered on my new-to-me equipment only to encounter a F059 error on the VFD. Despite finding 24v on S1, no voltage on S2, and 48v on S+, I am unable to enable the relays to open the main air supply to the machine. All safety operations are functioning properly, but there is no airflow. How can this issue be resolved?
Both terminals S1 and S2 must be linked to the positive terminal (S+) using either your safety circuit or jumpers.
The connection of both S1 and S2 to S+ is crucial for proper functionality, whether through a safety circuit or jumpers. It appears there may be an issue with the 24 volts on S2, while the presence of 48 volts on S+ indicates a potential internal problem within the drive. Further troubleshooting may be necessary to address these issues effectively.
What is your reference point for conducting voltage checks? Can you please specify the voltage between terminal 11 and terminal 4?
Safety inputs S1 and S2 are typically connected to S+ through dry contacts, enabling the signals to be transmitted effectively and securely. This configuration ensures optimal safety measures are in place for the system.
Robertmee inquired about the reference used for voltage checks and the specific voltage reading between terminal 11 and terminal 4. The voltage reading on the factory jumper connecting 11 and 2 is 48v. It is indicated that jumpers should be connected from terminal 1 to terminal 11.
From what you've explained, it sounds like the F059 error is signaling an issue with the Voltage Frequency Drive (VFD) unit of your equipment. Firstly, check the wiring connections of your VFD, as a faulty connection can sometimes signal this error. Also, ensure there's no overload, as this can inhibit the relay from activating. As S2 is showing no voltage, this could possibly mean an issue with the secondary relay or the power supply itself. If you can, try replacing the S2 relay and see if that resolves the issue. Remember, always take necessary precautions when dealing with electrical equipment.
