Operating Instructions ACU
Error in internal PLC function caused by user. Please refer to VPLC application manual.
Data transmission from control unit KP 500 to the frequency inverter not possible. At
least one file must be stored in the control unit.
The communication module was fitted to slot B without disconnection of the mains
voltage, switch mains voltage off.
After 6 warm starts in less than 3 minutes, this error will be triggered. Most probably,
the PLC or function table were programmed incorrectly. In addition, the function table
will be stopped (P.1399 = 0 in RAM only).
Output signals in the case of error messages
Errors are reported via digital signals.
A monitoring functions reports an error displayed via parameter Current
Error 259.
1)
For linking to frequency inverter functions
2)
For output via a digital output.
In addition to error signals mentioned, there are further error signals. However these messages are
only used for internal purposes and are not listed here. If you receive error signals which are not
listed here, please contact the BONFILGLIOLI customer service.
Please download the parameter file to your PC before contacting us.
21.2 Error environment
The parameters of the error environment help troubleshooting both in the settings of the frequency
inverter and also in the complete application. The error environment documents the operational
behavior of the frequency inverter at the time of the last four faults.
Direct voltage in DC-link.
Calculated output voltage (motor voltage) of the frequency
inverter.
The output voltage (motor voltage) of the frequency inverter.
Calculated from the data on speed sensor 1, the No. of Pole
Pairs 373 and the speed sensor signal.
Measured current in motor phase U.
Measured current in motor phase V.
Measured current in motor phase W.
Calculated effective output current (motor current) of the
frequency inverter.
Current component forming the magnetic flux or the calculated
reactive current.
Current component forming the torque or the calculated active
current.
Rotor Magnetizing
Current
Magnetizing current relative to the rated motor parameters and the
operating point.
Torque calculated from the voltage, the current and the control
variables.
