Control Functions
The following subsections describe the built-in motor control functions. For each function a simplified diagram is shown, the me-
aning of the command and monitoring data and a timing diagram of the relevant inputs and outputs. The control function can be
set-up using the listed parameters. To fulfill specfic requirements consult the Customer Specific Logic manual. The document num-
ber is listed in section How to get started.
The following basic diagrams always show the 24VDC supplied version of the UMC. A basic diagram with
UMC100.3 UC is provided in section "A2 Basic Circuit Diagrams".
Control Function Transparent
The UMC100.3 parametrised with the control function 'Transparent' behaves like an I/O module with an integrated overload check.
The outputs DO0 ... DO3 and the inputs DI0 ... DI5 are directly connected to the fieldbus and are independent of the overload status.
If a fault output (DO2 or DO3) is activated the relevant output cannot be controlled from the fieldbus anymore but is controlled by
the UMC itself.
The contactor k1 can be switched on and off for example using a standard maintaining circuit (not shown).
Alternatively it can be switched on and off from the control system which uses one of the UMC relay outputs to control the motor.
This option enables specific control logic to be implemented in the PLC.
The following features are not supported in this control function:
• Checkback supervision
• UMC controlled starting and stopping (bus, LCD, DI)
• Simulation and stop via multifunction inputs
• Bus fault reaction
• Voltage dip
