When accessing P02 with the keypad, take into account that the P02 data automatically updates data of
P03, P06 through P13, P53 and H46. Also, when accessing function code A16 for the 2nd motor, data of
related function codes for each are automatically updated.
H06
Cooling fan ON/OFF control
To prolong the service life of the cooling fan and reduce fan noise during running, the cooling fan stops when the
temperature inside the inverter drops below a certain level while the inverter stops. However, since frequent
switching of the cooling fan shortens its service life, the cooling fan keeps running for at least 10 minutes once
started.
H06 specifies whether to keep running the cooling fan all the time or to enable ON/OFF control.
H06 data
Function
0
Disable (Always in operation)
1
Enable (ON/OFF controllable)
■
Cooling fan in operation -- FAN (E20, E21 and E27, data = 25)
With the cooling fan ON/OFF control enabled (H06 = 1), this output signal is ON when the cooling fan is in
operation, and OFF when it is stopped. This signal can be used to make the cooling system of peripheral
equipment interlocked for an ON/OFF control
H11
Deceleration mode
H11 specifies the deceleration mode to be applied when a run command is turned OFF.
H11 data
Action
0
Normal deceleration
1
The inverter immediately shuts down its output, so the motor stops according to the
inertia of the motor and machinery (load) and their kinetic energy losses. Use this
setting to avoid regeneration when operation command is turned OFF.
When reducing the reference frequency, the inverter decelerates the motor according to the deceleration
commands even if H11 = 1 (Coast to a stop).
H72
Main power shutdown detection (Mode selection)
This function monitors the AC input power supply of the inverter to see if the AC input power supply (main circuit
power) is established and prevents inverter operation when the main circuit power is not established.
H72 data
Function
0
Disables main circuit power cutoff detection
1
Enables main circuit power cutoff detection
With power supply directly on the DC bus there is no AC input. When the data for H72 is "1," the inverter cannot
operate.
Change the data for H72 to "0”. It is not required to set this parameter for models up to/including
FRN0056E2S-2, and for models up to/including FRN0037E2S-4.
For single-phase supply, consult your Fuji Electric representatives.
H111
UPS operation Level
This parameter is used to set the minimum allowed DC link voltage to keep operation.

Data setting range: 150 to 220 VDC: (200 V class), 340 to 440 VDC: (400 V class)
