When setting parameters, refer to the instruction manual (applied) and understand instructions.
You can change the functions of the open collector output terminal
and relay output terminal.
This function is available only under IPM motor control.
You can control the operation of the cooling fan (1.5K or higher)
built in the inverter.
The inverter output current may be used to assume motor slip to
keep the motor speed constant.
This function is also enabled under V/F control.
You can choose whether to make earth (ground) fault detection at
start valid or invalid. Earth (Ground) fault detection is executed
only right after the start signal is input to the inverter.
As detection is executed at start, output is delayed for approx. 20ms every
start.
If an earth (ground) fault is detected with "1" set in
Pr. 249
, output
side earth (ground) fault overcurrent (E.GF) is detected and the
inverter trips.
Protective function will not activate if an earth (ground) fault occurs
during operation.
If the motor capacity is smaller than the inverter capacity when using
the 5.5K or higher, earth (ground) fault detection may not be
provided.

(initial value)
Cooling fan on/off control valid.
The fan is normally on during inverter
operation. The fan switches on/off according to
the temperature during a stop of the inverter
whose status is monitored.
