FeedRate Decel/Accel
VituralMaster.FeedRateDecelerationTime
This parameter 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.
FeedRate Override
VirtualMaster.FeedRateOverride
This parameter 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.
Initiate
VirtualMaster.Initiate
This initiates a Virtual Master index that generates virtual master pulses equivalent to VirtualMaster.Dist. The pulse rate will be defined by the
accel rate, velocity and decel rate. VirtualMaster.Initiate can be assigned or activated by a user program.
Marker Count
VirtualMaster.MarkerCount
The encoder marker pulses are simulated and this parameter (VirtualMaster.MarkerCount) specifies the number of
VirtualMaster.Counts per encoder marker pulse generated.
Minus Activate
VirtualMaster.MinusActivate
When active, this executes a Virtual Master jog in the minus direction that generates virtual master pulses as long as
the VirtualMaster.MinusActive is set. The pulse rate will be defined by the accel rate, velocity and decel rate.
VirtualMaster.MinusActivate can be assigned or activated by a user program
Plus activate
VirtualMaster.PlusActivate
When this parameter is active, this executes a Virtual Master jog in the plus direction that generates virtual master
pulses as long as the VirtualMaster.PlusActive is set. The pulse rate will be defined by the accel rate, velocity and
decel rate. VirtualMaster.PlusActivate can be assigned or activated by a user program.
Position Count
VirtualMaster.PosnCmdInCounts
This parameter is the number of virtual counts transmitted. Write to this parameter to zero it's value. It is only used
as a user display for virtual master debugging
Position Command
VirtualMaster.PosnCommand
This is the virtual position which uses VirtualMaster.PosnCmdInCounts and the conversion ratio to display the
position in user units. This is zeroed by clearing VirtualMaster.PosnCmdInCounts.
Posn Command
VirtualMaster.Stop
This parameter when activated stops the Virtual Master using the VirtualMaster.Decel rate.
Velocity
VirtualMaster.Vel
This parameter is the maximum virtual velocity that will be attained by the virtual master. This parameter is in user
units.
