REMARKS
• When running two motors with one inverter, you can set the electronic thermal relay function of each inverter.
... Output current value is used to perform integration processing.
... Output current is assumed as 0A to perform integration processing. (cooling processing)
... Electronic thermal relay function is not activated.
• It is valid for controlling one motor with one inverter in two different control systems.
• It is valid for controlling the first motor with an external thermal relay and the second motor with an electronic thermal relay
function.
