Application example: Roller conveyor with rotary table
A rotary table in a roller conveyor directs
the material at the crossing of two con-
veyor lines. The rotary table rotates
through 90° from one limit position to
the other. Two limit switches signal the
respective limit position. The signal to
start the rotary table comes from the
higher-level controller.
Procedure
1.
Connect the inverter to a commissioning tool, e.g. to an Operator Panel.
2.
Interconnect the limit position control of the inverter to the signals of the limit switches and
the higher-level controller.
p3340 = 722.0
Interconnect inputs of the limit position control to digital inputs of your choice
p3342 = 722.2
p3343 = 722.3
p0840 = r3344.0
Interconnect ON / OFF1 command. If the motor is to stop with a shorter
braking time than OFF1 when the limit position is reached, then interconnect
both the OFF1 command as well as the OFF3 command.
p0848 = r3344.1
r3344.2
Interconnect this signal, e.g. to a digital output of the inverter, to signal the
higher-level controller that the inverter is waiting for a 0
→
1 change of the
"Start rotary table" signal.
3.
Move the rotary table to one of the two end positions or open one of the limit switches
manually.
