6.5.15 CAMVM.RELATIVEDIST
General Information
Type R/W
Description
Specifies the number or counts that the virtual encoder (virtual master) will put
out during an incremental move (CAMVM.GOREL).
Units Encoder counts
Range -2^63 to 2^63-1
Default
Value
0
Data Type Integer
Start Ver-
sion
M_01-06-00-000
Description
The "move" is performed based upon the value of CAMVM.FREQ. The value of the virtual
encoder counter is in the variable CAMVM.POSITION. The modulo value EXTEN-
CODER.POSMODULO is applied to CAMVM.POSITION as well. You can check whether or
not the virtual encoder is moving using the variable CAMVM.MOVING. You can move the vir-
tual encoder (using CAMVM.GOREL or CAMVM.GOVEL) whether or not the drive is enabled
or disabled.
Example
This example moves the virtual encoder 100,000 counts at a frequency of 20,000 counts/sec-
ond. This move will take about 5 seconds.
'set up CAMVM.POSTION and virtual move param-
eters

CAMVM.POSTION = 0
CAMVM.RUNFREQ = 20000
CAMVM.RELATIVEDIST = 100000
'initiate the move
'------------------------
DRV.TIME = 0 'set time to zero just for meas-
urement
CAMVM.GOREL
'wait for the move to be complete
'----------------------------------------------
while CAMVM.MOVING = 1 : wend
'print the results
'----------------------
print "CAMVM.POSITION = ";CAMVM.POSITION
print "time = "; DRV.TIME
