SYSTEM PARAMETERS
Parameters can be changed and set using the keypad on the front panel (see Figure 4.1.1) to adjust the desired properties of the
inverter, such as ramp times, minimum and maximum frequencies, etc. The parameter numbers selected and the setting of the
parameter values are indicated on the four digit LED display.
Note:
If the
D
or
Ñ
button is pressed momentarily, the values change step by step. If the button is pressed for a longer time, the
values scroll through rapidly.
Access to parameters is determined by the value set in P009. Make sure that the key parameters necessary for the application have
been programmed.
Note:
In the following parameter table:
‘

Indicates parameters that can be changed during operation.
‘

’ Indicates that the value of this factory setting depends on the rating of the inverter.
Increased Parameter Resolution
To increase the resolution to 0.01 when changing frequency parameters, instead of pressing P momentarily to return to the parameter
display, keep the button pressed until the display changes to ‘- -.n0’ (n = the current tenths value, e.g. if the parameter value = ‘055.8’
then n = 8). Press
D
or
Ñ
to change the value (all values between .00 and .99 are valid) and then press P twice to return to the
parameter display.
Resetting to Factory Defaults
If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter
P944
to
1
and then
pressing
P
.
