Test operation
The frequency inverter versions SK 2x0E in size 4 and SK 2x5E, may be commissioned without any
auxiliary equipment for testing purposes.
For this, after electrical connection has been made (See Sections 2.7 and 2.8) DIP switches S1: 1 to 5
(Section 5.2.2.2) of the frequency inverter must be set to the position "0" ("OFF") and the digital input DIN1
(Terminal 21) must be permanently wired to the 24 V control voltage.
Enabling is carried out as soon as the inverter's own setpoint potentiometer (Potentiometer P1, Section ) is
moved from the 0% position.
The setpoint can be adjusted to the requirements by further continuous adjustment of the potentiometer.
Resetting the setpoint to 0% sets the frequency inverter into "Standby" status.
Stepwise adjustment of the ramp times within defined limits is also possible with the aid of potentiometer
P2.
NOTE
This setting method is not suitable for the implementation of a so-called "automatic start with
mains".
In order to use this function, it is essential that parameter (P428) "Automatic Start" is set to the
function "ON". Adjustment of parameters is possible with the aid of a ParameterBox
(SK xxx-3H) or with the NORD CON software (Windows PC and adapter cable required).
