Parameterization 5.4.4.2 Operation Diagram – Direct Starter Start Stop O1 - K1 TRIP Reset Check Back Motor current / Input I3 Figure 5.8 - Operation diagram for the Direct Starter Operation Mode 5.4.5 Reversing Starter In this mode a reversing starter for three-phase motors is configured. The digital outputs O1 and O2 are reserved for the operation of the motor starting contactors (internal use). The other digital outputs can be used according to the user’s needs (free). In case of a TRIP, the digital outputs O1 and O2 switch off the starting contactors, thus stopping the motor. For the Control Unit (UC) connection diagram presented in the section 5.4.5.1, the digital inputs and outputs are configured according to the table 5.5. Table 5.5 - Configuration of the digital inputs and outputs for the Reverter Starting operation mode Function Digital Inputs /Outputs I1 5 Local/Remote Commands using Digital Inputs Control Logic 3 wires (P230 = 1) (Pushbuttons) Control Logic 2 wires (P230 = 0) (Switch) Stop Pushbutton Free I2 Direct ON Button Direct ON/OFF switch I3 Reverse ON Button Reverse ON/OFF switch I4 (*) Check Back O1 Forward Contactor Operation O2 Reverse Contactor Operation O3 Ladder O4 Ladder (*) Adjust P208 according to the application. NOTE! In the example above, the Check Back signal was configured for digital input, P208 = 1. The factory setting is Check Back by motor current, P208 = 0. If P208 = 0, then the digital input I4 becomes free for the user. 5-17
