For the allocation of further inputs and outputs / voltage supplies,
see the terminal configuration
To operate the MEG C 40 with the MEG 40 EC, at least the
following terminals need to be connected:
• Supply voltage (terminals 10 and 12)
• Supply voltage of the digital I/Os (terminals 16 and 17)
• Connection of the MEG 40 EC gripper (terminals 1, 3, 7, 9)
• Digital inputs "Gripper open" (terminal 21) and "Gripper
closed" (terminal 20)
The other inputs and outputs must be assigned in accordance with
the application or relevant case. After connecting the supply voltage,
the Status LED flashes six times and then lights up continuously. The
MEG C controller is then ready for operation. If the Status LED flashes
constantly after switching on the MEG C, this indicates a malfunction
and you will need to perform a fault analysis
A new command is always carried out with a rising edge on the
digital inputs. This command in turn is completed with a falling
edge. During command execution it must be ensured that the
input signal does not bounce.
The gripper opens if a rising edge is identified at the "Gripper
open" input. In the event of a falling edge, the command is ended,
and the gripper stops. This works in the same way for the "Gripper
closed" input. It is necessary to end the previous command with a
falling edge before a new command is executed. In other words, it
is imperative to ensure that the previous command was ended
with a falling edge.
5.3 Performing a reference run
The reference run is only required if the analog output "Analog
position output" (terminal 15) is to be used in the application. A
reference run can be performed outward or inward.
Procedure
Ø
Apply a High signal to the digital input "Reference
run" (terminal 19).
Ø
In the case of a reference run outward, apply a High edge to the
digital input "Gripper open" (terminal 21).
Ø
In the case of a reference run inward, apply a High edge to the
digital input "Gripper closed" (terminal 20).
Ø
Wait until the digital output "Reference run
performed" (terminal 14) has been set to high.
Ø
After having performed the reference run, set the inputs
"Reference run" and "Gripper open" or "Gripper closed" to Low
signal.
