Check the board is properly connected and it is not damaged.
How to fix I/O board or external communication board fault on Power Electronics SD300 Inverter?
Check the board is properly connected and it is not damaged.
What does BX error mean on Power Electronics SD300?
The Power Electronics Inverter is being forced to cut the output supply and stop due to inertia.
What does Pipe Fill Flt mean on a Power Electronics SD300?
An error has been detected on the Power Electronics Inverter, which makes the PID feedback always be under the established value. This could indicate a possible pipe breakdown.
What does Slot 1 Fail mean on a Power Electronics SD300 Inverter?
The optional board located in slot 1 of the Power Electronics Inverter has been extracted, or there is no possible communication.
What does Param_Wr_Err mean on Power Electronics Inverter?
A problem has been detected during the writing of a parameter by keypad on the Power Electronics Inverter.
Why does my Power Electronics SD300 show an overvoltage error?
The Power Electronics Inverter trips if the DC voltage within the bus exceeds the established value. This can occur during deceleration, when the motor's regenerative energy return to the drive is excessive for the capacitors in the DC bus, or due to a temporary overvoltage in the supply system.
What does STO error mean on a Power Electronics SD300?
Automatic internal protection of several of the IGBT semiconductors has activated, or the safe stop contact of the Power Electronics Inverter (connected to an external circuit by the user) has been activated (for example, an emergency stop).
What does Lost command mean on Power Electronics SD300 Inverter?
The Power Electronics Inverter trips due to a loss of speed set point established by the use of the control or communication terminals.
What does External Trip mean on a Power Electronics SD300 Inverter?
This function is used when the user needs to cut the output using an external trip signal. The open/closed contact use depends on the configuration within the digital inputs (In.65-In.71) configured as 4 'EXTERNAL TRIP'. The Power Electronics Inverter cuts the motor output, protecting it from the controlled situation within the terminal.
Why does my Power Electronics SD300 Inverter show a No Motor error?
The Power Electronics Inverter has not detected a connected motor at its output when the start order was given. This protection is enabled when parameter Pr.31 is set to a value other than 0 ('NONE').
