Parameter lock function
0000: Enable all Functions
0001: A059 - A068 cannot be changed
0002: All Functions Except A059 - A068
cannot be changed
0003: Disable All Functions
A040 Parameter Copy
0000: Disable
0001: Inverter to Copy Unit
0002: Copy Unit to Inverter
0003: Verify
1.) A040 = 0000
:
The
Inverter copy operation is not in the copy mode.
2.) A040 = 0001
:
Copy the inverter parameters to keypad module.
3.) A040 = 0002
:
Copy the keypad module parameters to inverter.
4.) A040 = 0003
:
Compares the parameters in the inverter to the parameters in the keypad module.
Note:
If there is a mismatch,
error message “EPr2” will be displayed.
Note: The copy function is only available for the models with same ratings.
A041 Fan Run Control
0000: Auto (Depends on temperature)
0001: Operate while in RUN Mode
0002: Always Running
0003: Always Stopped
1.) A041 = 0000
:
The fan runs when the inverter temperature rises above a set level.
2.) A041 = 0001
:
The fan runs while the inverter is running.
3.) A041 = 0002
:
The fan is continuously running regardless of the status of the inverter.
4.) A041 = 0003
:
The fan is always stopped regardless of the status of the inverter.
Note: The function is disabled at and above 15HP for the 230V class and above 20HP for the 460V class,
for these models, the fan will run continuously after power up.

0000: Disabled
0001: Controlled by MFIT at Set Frequency

)
1.) With fans, pumps or other high inertia loads, starting torques are typically high. When set speed is reached
the torque demand becomes less, consequently the output voltage can be lowered to save energy by setting
parameter A042 = 00001.
2.) Setting A050 - A056 = 10 (Multifunction input terminal) enables energy saving.
3.) If the multifunction terminal is set to =10 (energy saving control terminal), and A042 = 0001, the output voltage
will gradually decline to the original voltage x A043 (0-100%) when the terminal is ON. When the terminal
is OFF the output voltage will rise to original voltage.
Note: a. Energy saving mode is only available in the V/F mode. (A000 = 0002)
b. The declining and rising speeds of voltage for energy saving are the same as those for Speed Search.
