What causes an underload error on a Power Electronics SD300 Inverter?
The motor connected to the Power Electronics Inverter is working with insufficient load. The drive trips when its current is within the values set in parameters Pr.29 and Pr.30, exceeding the time limit set in parameter Pr.28. The protection is enabled if parameter Pr.27 is set to a value other than 0 ('NONE').
What does Input Ph Loss mean on a Power Electronics SD300?
One of the three input phases is open on the Power Electronics Inverter. The protection is enabled if parameter Pr.5 is set to 2 ('INPUT') or 3 ('ALL').
What does Output Ph Loss mean on a Power Electronics Inverter?
One of the three output phases is open on the Power Electronics Inverter. This protection is enabled if parameter Pr.5 is set to 1 ('OUTPUT') or 3 ('ALL').
What does fan trip mean on a Power Electronics SD300?
An anomaly has been detected within the cooling fan of the Power Electronics Inverter. This protection is enabled if parameter Pr.79 is set to 0 ('TRIP').
What causes LV error on Power Electronics SD300?
The Power Electronics Inverter trips when the voltage within the DC bus is below the detection level. This can result in insufficient torque or motor overheating if the input voltage decreases.
What does Short ARM mean on Power Electronics SD300?
The Power Electronics Inverter trips when a short-circuit occurs in the IGBT or in the output power.
What does E-Thermal mean on a Power Electronics SD300?
The internal thermo-electronic protection determines if the motor is overheating. If overheating occurs, the Power Electronics Inverter stops its output. This protection is enabled by setting parameter Pr.40 to a value other than 0 ('NONE').
What causes a ground fault in a Power Electronics Inverter?
The Power Electronics Inverter trips when earth leakage and its current exceed the internal configured value. The overload protection function protects the drive from ground faults caused by small leakage resistance.
What does inverter overload mean on a Power Electronics SD300 Inverter?
The Power Electronics Inverter cuts the output supply when the output current exceeds the set parameters (150% for 1 minute, or 200% for 3 seconds of the drive's rated current). This protection is based on the drive's rated capacity, which varies depending on the device capacity.
What causes an overcurrent in a Power Electronics SD300 Inverter?
The Power Electronics Inverter drive trips when the output current exceeds 200% of its rated value.
Explains how to mount the SD300 drives on a wall or inside a panel, emphasizing fire resistance and clearance.
Provides installation recommendations for power connection and wiring, including safety checks for DC link discharge.
Explains the procedure for properly grounding the drive chassis and motor to ensure safety and prevent interference.
Advises on parallel cable routing, distance maximization, and using shielded cables for data and control signals.
