Before Applying Power to Your Controller for the First Time
For information on the connections mentioned hereafter, refer to the Electrical Connections Overview.
To wire the controller, proceed as follows:
|
Step
|
Action
|
|
1
|
Be sure that the controller is first connected to the ground (functional earth) before proceeding with other connections.
|
|
2
|
Verify the continuity of the grounding system of your application.
|
|
3
|
Verify that all cable shields are properly connected to the functional earth of the application.
|
|
4
|
Verify that the memory card has been inserted.
|
|
5
|
Eliminate the possibility of short circuits and interruptions.
|
|
6
|
Verify that the terminals are fastened securely and the cable cross sections (gauge) are as required.
|
|
7
|
Connect the CN9 connection of the controller to an appropriate power supply.
|
|
8
|
Establish a Sercos connection via the CN5 and/or CN6 connections.
NOTE: If Sercos devices are assigned via the topological addresses ( = ) to the PacDrive LMC Eco, then consider the following:
-
Connect your Sercos device to the PacDrive LMC Eco either completely via Sercos port 1 (CN5) in line topology or in ring topology using Sercos port 1 and 2 (CN5/CN6).
-
Do not connect the Sercos devices to the PacDrive LMC Eco via double line topology (CN5/CN6).
-
Do not connect the Sercos devices to the PacDrive LMC Eco only via Sercos port 2 (CN6).
|
|
9
|
Connect all further connections according to the requirements of your application.
|
|
10
|
Power on the supply voltage to the controller.
Result: The LMC is initialized and the LEDs show the following condition:
|
|
DANGER
|
|
INSUFFICIENT GROUNDING
-
Use a protective ground copper conductor with at least 10 mm2 (AWG 6) or two protective ground copper conductors with the same or larger cross section of the conductors supplying the power terminals.
-
Verify compliance with all local and national electrical code requirements as well as all other applicable regulations with respect to grounding of all equipment.
Failure to follow these instructions will result in death or serious injury.
|
|
WARNING
|
|
UNINTENDED EQUIPMENT OPERATION
Verify the connection of the control voltage to the inputs and outputs.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
|
Refer to the chapter Electrical Connection Overview.
Configure the Output CN8 as Watchdog
On the connection CN8, it is possible to configure the output DQ7 as watchdog output. By default, the output is configured as standard output.
|
WARNING
|
|
NON-CONFORMANCE TO SAFETY FUNCTION REQUIREMENTS
Do not use the watchdog output to realize any safety function.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
|
For more information on safety functions, consult the standards IEC 61508:2010 and EN ISO 13849:2008.
For further information on this, see the online help of EcoStruxure Machine Expert.
Grounding Screw Connection
Tighten the grounding screw with a 1.4 Nm (12.4 ibf in) torque.
External UPS
The controller saves data up to 25 ms after a power outage. To avoid data loss, an external uninterruptible power supply (UPS) should be used.
|
NOTICE
|
|
LOSS OF DATA
Use an external UPS to avoid data loss in case of a power outage.
Failure to follow these instructions can result in equipment damage.
