Parameter Comparison
1,2,3
RW
Use this parameter to initiate a Parameter Comparison function, you can compare the actual parameter
values to the values of your customized parameter sets and those loaded to the control keypad.
The actual parameter values are first compared to those of the customized parameter Set1. If no differences
are detected, a “0” is displayed on the lowermost line of the keypad.
If any of the parameter values differ from those of the Set1 parameters, the number of the deviations is
displayed together.
By pressing the right arrow button once again you will see both the actual value and the value it was
compared to. In this display, the value on the Description line (in the middle) is the default value, and the one
on the value line (lowermost line) is the edited value. You can also edit the actual value by pushing the Right
Arrow button.
Actual values can also be compared to Set2, Factory Settings and Keypad Set values.
P13.1.7
624
Password
1,2,3
RW
Use this parameter to setup a password to protected against unauthorized changes. When the password
function is enabled, the user will be prompted to enter a password before application changes, parameter
value changes, or password changes.
By default, the password function is not in use. If you want to activate the password, change the value of
this parameter to any number between 1 and 9999.
To deactivate the password, reset the parameter value to 0.
P13.1.8
625
Parameter Lock
1,2,3
RW
Use this parameter to prevent user from changing parameters. User has to come to this parameter to allow
changing. When the parameter lock is activated the text *locked* will appear on the display if you try to edit
a parameter value.
Note: This function does not prevent unauthorized editing of parameter values.
P13.1.9
627
Multimonitor Set
1,2,3
RW
Use this parameter lock in the values set for the mult-monitor page and not allow changing unless
re enabled.
P13.1.10
628
Default Page
1,2,3
RW
This parameter sets the view to which the display automatically moves as the Timeout Time expires or when
the keypad power is switched on.
If the Default Page value is 0, the function is not activated, i.e., the last displayed page remains on the
keypad display.
P13.1.11
629
Timeout Time
1,2,3
RW
Use this parameter to set the time after which the keypad display returns to the Default Page, if no keypad
keys are pressed.
Note: If the Default Page value is 0 the Timeout Time setting has no effect.
P13.1.12
630
Contrast Adjust
1,2,3
RW
Use this parameter to adjust the display by changing the contrast.
P13.1.13
631
Backlight Time
1,2,3
RW
Use this parameter to set the time to illuminate the display.
P13.1.14
632
Fan Control
1,2,3
RW
This function allows you to control the drives cooling fan. You can set the fan to run:
0 = Continuous—fan runs continuously.
1 = Temperature—based on the temperature of the unit. The fan is switched on automatically when the heat
sink temperature reaches 60°C. The fan receives a stop command when the heat sink temperature falls
to 55°C. The fan runs for about a minute after receiving the stop command or switching on the power, as
well as after changing the value from “Continuous” to “Temperature.”
2 = Run Follow —after power up, the fan is stopped until the run command is given and then fan runs
continuously. This is mainly made for common DC-bus systems to prevent cooling fans to load charging
resistors on power up moment.
3 = Calculate IGBT Temp—starting of cooling fan is based on calculated IGBT temperature.
When IGBT temp = 40°C, fan starts and when temp falls down to 30°C, fan stops.
