H5 Serial Communication Set-up

Selects the stopping method after a transmission error is detected.

H5-05 enables or disables the MODBUS time out detection function. After initial communication

begins, if communication is interrupted for longer than 2 seconds, then a communication fault will

occur.

During a communication fault, the following fault code will be displayed: “CE Memobus Com Err”.

L Protection Parameters

L1 Motor Overload

The VS-616G5 protects against motor overload with a UL-recognized, built-in electronic thermal

overload function.

Selects whether motor overload protection is provided.

The electronic thermal overload function estimates motor temperature, based on inverter output cur-

rent and time, to protect the motor from overheating. When the electronic thermal overload relay is

activated, an “OL1” error occurs, shutting OFF the inverter output and preventing excessive overheat-

ing in the motor. As long as the inverter is powered up, it continues to calculate the motor temperature.

When operating with one inverter connected to one motor, an external thermal relay is not needed.
