5. SYSTEM PARAMETERS
Parameters can be changed and set using the membrane-type buttons 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 in the four digit LED display.
Note: If you press the ∆ or ∇ button momentarily, the values change step by step. If you keep the buttons
pressed for a longer time, the values scroll through rapidly.
Access to parameters is determined by the value set in P009. Check that the key parameters necessary for
your 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.
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 ∆ or ∇ to change the value (all
values between .00 and .99 are valid) and then press P twice to return to the parameter display.
If parameters are changed accidentally, all parameters can be reset to their default values by setting
parameter P944 to 1 and then pressing P.
