LSIS VFDs installed at an altitude of 1000m above sea level or less do not require a derate. VFDs installed at an altitude between 1000 to 4000m require a derate of 3% for every 300m over 1000m.For calculating the derate, please refer to the attached Excel calculator or the example below.Example:A VFD is installed and an altitude of 2000m above sea level.Formula: ((Altitude - 1000)/300) * .03 = Derate Percentage((2000m - 1000)/300) *.03 = .10 or a 10% Derate
On LS drives, Modbus RTU communication addresses are offset by one (decremented). Alternatively, Modbus TCP/IP has no offset.See attachment for Modbus RTU offset.
The necessary parameters will vary greatly depending on the application.

"Class" is an important rating in regards of overload relays(OLRs). The "Class" specifies the maximum amount of time the overload will allow 6x (600%) of the full load rating of the OLR before tripping.For example, a Class 20 OLR will allow 600% of its rated full load current for up to 20 seconds before tripping.
