When parameter , level of electronic thermal setting, is set to motor FLA
rating (Full Load Ampere nameplate rating), the inverter provides solid state
motor overload protection at 115% of motor FLA or equivalent. If parameter
 exceeds the motor FLA rating, the motor may overheat and be dam-
aged. Parameter , level of electronic thermal setting, is a variable param-
eter.
• Inverter and motor models are be treat separately:
• E05 error will be reported in case of Motor overload
• E38 error will be reported in case of Inverter overload
• Inverter protection is set to constant torque characteristic and inverter
rated current
The characteristic curve depends on dual rate setting in  as follows.
