Motor overload Overload protection of motor 2 only when P24.04 bits equals one or overload protection of
motor 1 or P24.08 bits equals one. P24.00 is used to adjust the overload inverse time curve time, as shown in
the right figure above, the minimum motor overload time is 5.0s.
Note: Users need to correctly set the three parameters of P24.00, P24.01 and P24.02 according to the actual
overload capacity of the motor. If set unreasonable, prone to motor overheating damage and the inverter is not
timely warning of the danger of protection.

Motor in self cooling mode, heat
dissipation is poor when in low
frequency but good in condition of high
frequency . P24.01 adn P24.02 is used to
set the starting point of zero and rated
speed overload current in order to
obtain a more reasonable under
different speed overload protection
