Summary

velocity synchronization with the master

Syntax

SYNCV

NB!

SYNCV should only be called up once since

the synchronizing continues until the next

motion or stop command. All additional SYNCV

commands cause the synchronization to start over

again from the beginning and this is not normally

intended, as you reset the actual SYNCERR.

NB!

Position error is not monitored in SYNCV

mode, it is therefore recommendable to use

the hardware encoder monitor.

Command group

SYN

Cross Index

parameter of the AXS group

■

SYSVAR

The system variable SYSVAR – a prepared pseudo

array – provides detailed system information. You

also need this index if you link the system variable

with the LCP display using LINKSYSVAR or specify

recording data of a test run with TESTSETP.

Summary

System variable (Pseudo array) reads system values.

Syntax

SYSVAR[n]

n = index

System Process Data

Index Description

Input Byte 0 (I1 … I8)
