DescriptionSets the drive/motor to operate in the voltage external mode. In this mode, the drive/motor performs a voltage control with a voltage reference provided by another device. There are 2 types of external references (selectable via the TML instruction EXTREF):
•Analogue – read from a dedicated analogue input (TML variable AD5)
•Online – received online via a communication channel from a host and saved in the TML variable EREFT

When the voltage reference is read from the analogue input, the reference update can be done in 2 ways:

•MODE VES – at each slow loop sampling period
•MODE VEF – at each fast loop sampling period

 

When the voltage reference is received online via a communication channel only option MODE TES is possible.

Remark: The voltage contouring mode has been foreseen for testing during the setup phase

 

The new motion mode becomes effective at the next update command UPD.

 

Example

//Read voltage reference from variable EREFV

EREFV = 30;// EREFV initial = 30[IU]

EXTREF 0;

MODE VES; //External voltage

UPD; //execute immediate
