Setting The Plc Cycle Time In Twincat® Plc Control; Configuration As A Twincat® Nc Axis; I/O Configuration For Servo Drives Used As Nc Axes - Danfoss VLT ISD 510 Operating Manual

VLT® Servo Drive System ISD 510/DSD 510
Operating Guide
-
Connect the PSM 510, DAM 510, and ACM 510 to 1 SYNC unit and the ISD 510/DSD 510 servo drives to another. This protects
against interruptions in communication to the PSM 510 and DAM 510 if the U
due to an error.
6.11.14 Setting the PLC Cycle Time in TwinCAT® PLC Control
The minimum cycle time is 400 µs. The ISD 510 devices can run EtherCAT
are automatically parameterized by the PLC on start-up, depending on the EtherCAT
cess the system base time, select [SYSTEM-Configuration → Real-Time Settings] in the TwinCAT
base time can then be used as EtherCAT
-
Set the task cycle time of the PLC program to be the same as the EtherCAT
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

-
After changing the task cycle time in TwinCAT® PLC Control, carry out a ReScan of the PLC configuration in-
side the TwinCAT® System Manager to update the settings. Afterwards, activate the configuration in the PLC.
6.11.15 Configuration as a TwinCAT® NC Axis
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
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
last step, answer the question if the servo drive is used as an NC axis with Yes. Then an NC task is created automatically.
