4. You now have the possibility to control your drive via its parameters and to check itsstatus.Ä Chap. 13.3.7.1 ‘FB 875 - VMC_AxisControl_PT - Axis control via PulseTrain’ page 423There is the possibility to control your drive via an HMI. For this purpose, a predefinedsymbol library is available for Movicon to access the VMC_AxisControl_PT functionmodule.Ä Chap. 13.8 ‘Controlling the drive via HMI’ page 61313.3.7 Drive specific block13.3.7.1 FB 875 - VMC_AxisControl_PT - Axis control via Pulse Train13.3.7.1.1 DescriptionWith the FB VMC_AxisControl_PT you can control axis, which are connected via PulseTrain. You can check the status of the drive, turn the drive on or off, or execute variousmotion commands. A separate memory area is located in the instance data of the block.You can control your axis by means of an HMI.Ä Chap. 13.8 ‘Controlling the drive viaHMI’ page 613The control of a pulse train drive happens exclusively with the FB 875VMC_AxisControl_PT.
