The LSIS DC Drive shuts down its output when a ground fault occurs and the ground fault current exceeds the inverter's internal setting value.
What causes inverter overload in LSIS DC Drives?
The LSIS DC Drive will turn off its output when the output current exceeds the rated level (150% for 1 minute), indicating an inverter overload.
Why does LSIS DC Drives show an over voltage error?
The LSIS DC Drive turns off its output if the DC voltage of the main circuit rises above 400V during motor deceleration, which is often caused by a surge voltage in the power supply system.
What causes heat sink overheat in LSIS DC Drives?
The LSIS DC Drive will turn off its output if the heat sink overheats. This can be caused by a damaged cooling fan or foreign objects obstructing the cooling fan.
Why does LSIS DC Drives show a low voltage error?
The LSIS DC Drive turns off its output if the DC voltage drops below 180V. This is because insufficient torque or overheating of the motor can occur when the input voltage of the inverter drops.
What causes output phase loss in LSIS DC Drives?
The LSIS DC Drive turns off its output if one or more of the output phases (U, V, W) are open.
What does communication error mean on LSIS DC Drives?
This fault message appears on LSIS DC Drives when the inverter cannot communicate with the keypad.
What does cooling fan fault mean on LSIS DC Drives?
This fault message is displayed when a fault condition occurs in the LSIS DC Drive's cooling fan.
What causes instant cut off in LSIS DC Drives?
The inverter instantly turns off the output when the EST terminal is turned on in LSIS DC Drives.
What does external fault A contact input mean on LSIS DC Drives?
When the multi-function input terminal (I20-I24) is set to 19 {External fault signal input : A (Normal Open Contact)}, the LSIS DC Drive turns off the output.
