Danfoss VLT5000 SyncPos Operating Instructions Manual page 157

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.

■ ■ ■ ■ ■ 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

Axis Process Data
Index Description
4096 Current position slave in qc (without conver-
sion to UU) (see APOS)
4097 Set position slave in qc (without conversion to
UU) (see CPOS)
4098 Last slave index position in qc (without conver-
sion to UU) (see IPOS)
4099 Actual velocity in qc/st, where st is the sample
time set by _GETVEL.
4100 Current velocity Master (as above)
4101 Current position error in qc
4102 Contains the number of revolutions of the en-
coder after the first overflow of the absolute
encoder, provided the graduation per revolu-
tion is entered correctly in ENCODER (2).
4103 As above for the master
4105 Current master position without conversion
(qc) (see MAPOS)
4106 Last Master index position without conver-
sion (qc) (see MIPOS)
4107 Internal current velocity (ACTPOS – last
ACTPOS) (qc/1 ms)
4108 Internal Master velocity (see above)
