Reversing Starter (REV)

Use this function in a feeder that requires a motor to start/stop in two directions of rotation (forward / backwards).

Function Block

Inputs (from top to bottom)

Output (from top to bottom)

Parameters

Signal Name

Rev: Start motor in a reverse direction

Stop: If logical 1 the motor will be stopped and cannot be started until the input changes to

logical 0 level.

For: Start motor in a forward direction

Voltage DIP: Signals a voltage DIP situation which is triggered by an external device (e.g.

central voltage monitor).

DO2 / DO3: Inputs not used from the starter. Depending on the fault output configuration

also DO2/DO3 is controlled from the function block.

Rev Status (Reverse): If the motor is running in reverse direction the output is set to active 1

Stop Status: If the motor has been stopped this output is set to active 1

For Status (Forward): If the motor is running in forward direction 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.

Rev Lockout Time Running: When locical-1 the lockout time is running and a start signal is

ignored.

Status DO0 ... DI3: Mirror of the digital outputs of the UMC.

See section "Control Function Reversing Starter" in the UMC100 manual.
