Test operation
The frequency inverter versions SK 2x0E in size 4 and SK 2x5E may be commissioned without any
auxiliary equipment for testing purposes.
In order to do this, after making the electrical connection (please see chapter 2.4 "Electrical
Connection"), set DIP switches S1: 1 to 5 of the frequency inverter to position "0" ("OFF") (please see
chapter 4.3.2.2 "DIP switches (S1)")and hard-wire digital input DIN1 (terminal 21) to a 24 V control
voltage.
Enabling is carried out as soon as the inverters 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.
Information
Test operation
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).
