NOTICE
-
Set the task cycle time of the PLC program to be the same as the EtherCAT
®
cycle time. Otherwise data may be lost and
performance reduced.
Procedure
1. Double-click
Task configuration
in the
Resources
tab.
2. Ensure that the PLC cycle time is the same as the EtherCAT
®
cycle time.

Illustration 80: Task Configuration to Parameterize the PLC Cycle Time
NOTICE
-
After changing the task cycle time in
TwinCAT® PLC Control
, carry out a
ReScan
of the PLC configuration inside
the
TwinCAT® System Manager
to update the settings. Afterwards, activate the configuration in the PLC.
6.12.15 Configuration as a TwinCAT® NC Axis
Context:
The servo drives can be used with the built-in NC functionality of TwinCAT
®
.
Everything that is related to the PSM 510 and DAM 510 must be done as described in
6.12.2 Creating a TwinCAT® Project
.
Procedure
1. In addition to the
Danfoss_VLT_ServoMotion_V_x_y_z.lib
file, include the
TcMC2.lib
file.
2. Create 1 instance of
AXIS_REF
(instead of
AXIS_REF_DDS
) for each ISD 510/DSD 510 servo drive that is used as an NC axis.
3. Append the PLC project into the TwinCAT
®
System Manager, import the devices, and add them to TwinCAT
®
, however in the last
step, answer the question if the servo drive is used as an NC axis with
Yes
. Then an NC task is created automatically.
6.12.15.1 I/O Configuration for Servo Drives used as NC Axes
Context:
In the TwinCAT
®
System Manager, select a different I/O Configuration for the servo drives used as NC axes.
