3.8.2

Virtual Master Setup Group

Distance

Distance (VirtualMaster.Dist) is the incremental distance virtual master will move, in user units, if the virtual master is initiated 
as an index.

Velocity

Velocity (VirtualMaster.Vel) is the maximum virtual velocity that will be attained by the virtual master. This parameter is in user 
units.

Acceleration

Acceleration (VirtualMaster.Accel) is the acceleration rate, in user units, that the virtual master will use to accelerate. This 
parameter is used when in either jog or indexing mode. 

Deceleration

Deceleration (VirtualMaster.Decel) is the deceleration rate, in user units, that the virtual master will use to decelerate in either 
jog or index mode.

Marker Count

The encoder marker pulses are simulated and this parameter (VirtualMaster.MarkerCount) specifies the number of 
VirtualMaster.Counts per encoder marker pulse generated.

3.8.3

Virtual Master Conversion Ratio Group

Scaling

Converts the user units distance into virtual counts.

VirtCnts

The numerator (top value of the scaling fraction) is the VirtualMaster.CharacteristicLength. The characteristic length is the 
number of virtual counts that will be generated per the distance, in user units, defined by the denominator (bottom number of 
the scaling fraction). 

Distance (UserUnits)

The denominator (bottom value of the scaling fraction) is VirtualMaster.CharateristicDistance, in user units, and is used with 
VirtualMaster.CharacteristicLength to create the virtual master conversion ratio.

Example:

If the user sets the numerator to 10,000 and the denominator to 1 revs, then 10,000 virtual counts will be sent out when the 
virtual master produces 1 rev of virtual motion.

3.8.4

Feedrate Group

FeedRate Override

This parameter (VirtualMaster.FeedRateOverride) is used to scale the Virtual Master counts. It can be described as “scaling in 
real time”. The default setting of 100% will allow all counts to occur in real time. A seeing of 50% will scale time so that all 
counts are half as fast as they are at 100%. A setting of 200% will scale time so that all count run twice as fast as they would 
at 100%. Feed Rate Override is always active, and this parameter may be modified via Modbus, Ethernet, or in a program.

FeedRate Decel/Accel

FeedRate Decel/Accel (VirtualMaster.FeedRateDecelerationTime) specifies the ramp used when velocity changes due to a 
change in the FeedRate Override value. The units of FeedRate Decel/Accel are seconds/100%. Therefore, the user must 
specify the amount of time (in seconds) to accelerate or decelerate 100% of programmed feedrate.

3.9

Position View

The Position View allows you to set up and view the parameters related to drive positioning. In Figure 44, Position has been 
selected in the Hierarchy Tree. The right side of the view is divided into groups. An explanation of the groups and their 
functions is provided below.
