only is designed so that its setting can be changed anytime even when it is set at .
To prohibit all operation, including key operation, use the parameter (Panel operation
prohibition).
6.29.2 Changing the units of display
Current / voltage display mode
Example of setting
When the VFA7-2037PL (rated current: 16.6A) is operated under the rated 100% load :
1) Display in [%] 2) Display in [A] or [V]
Title Function Adjustment range Default setting
Current / voltage display
mode
: [%]
: [A] or [V]
Function
This parameter is used to change the units of display of current and voltage.
Display in % <=> Display in A (ampere) or V (volt)
Current 100% = Inverter’s rated current
200V-class voltage 100% = 200Vac
400V-class voltage 100% = 400Vac
Output current
: 16.6A
Input voltage
: 200V
DC voltage
: 100%
Output current
: 100%
With , you can convert the units pertaining to the following parameters:
Display in [A]: Current monitor
Motor overload protection level #1,#2,#3,#4 , , ,
DC injection braking current
Stall prevention level
Display in [V]: Voltage monitor
V/f 5-point setting , , , ,
Note Base frequency voltage is always displayed in voltage unit.
Function
This parameter is used to make a setting to prohibit or allow the change of parameter settings.
