Sets whether the motor over-
load function is enabled or
disabled at electric thermal
overload relay.
0: Disabled

protection
2: Inverter motor protection
3: Vector motor protection
In some applications when
the Inverter power supply is
turned off, the thermal value
is reset, so even if this
parameter is set to 1,
protection may not be
effective.
When several motors are
connected to one Inverter,
set to 0 and ensure that each
motor is installed with a pro-
tection device.
