Control Functions
A control function block is available for the different type of starters supported by UMC. The function blocks realise the
complete start / stop logic as well as the timing and checkback supervision of the contactor(s).
Depending on the control function some of the digital outputs have predefined functions. Therefore the digital outputs are
not accessible directly but only via these function blocks. If an output is needed by the function block itself it is not available
for the application.
The function blocks also handle the fault output which can be configured in steady state or flashing mode.

Direct Online Starter (DOL)
Use this function in a feeder that requires a motor to start/stop in one direction of rotation.

Parameters
Signal Name
Stop: If logical 1 the motor will be stopped and cannot be started until the input changes
to logical 0 level.
For: Start motor
Voltage DIP: Signals a voltage DIP situation which is triggered by an external device (e.g.
central voltage monitor).
DO1 ... DO3: Inputs not used from the starter. Depending on the fault output configuration
also DO2/DO3 is controlled from the function block.
Stop Status: If the motor has been stopped this output is set to active 1
For Status (Forward): If the motor is running the output is set to active 1
CB Fault: A checkback fault has occurred.
Start Time Run: During motor start this output is set to logical 1.
Status DIP: Signals that the voltage DIP function is active. See UMC100 manual for more
information about voltage DIP.
Status DO0 ... DI3: Mirror of the digital outputs of the UMC.
See section "Control Function Direct Starter" in the UMC100 manual.
