Virtual Master - Parker AC890 Product Manual

VIRTUAL MASTER

SETUP::PHASE CONTROL::VIRTUAL MASTER
This block transmits a regular update of speed, position and acceleration to all other drives listening on the selected channel.
The output is profiled by the ACCELERATION, DECELERATION and JERK 1-4 parameters.
Refer to REFERENCE RAMP, page D-127.
An example acceleration graph for a velocity 60 %/s maximum, acceleration of 20 %/s
Parameter Descriptions
CHANNEL
This parameter sets the Firewire channel that the Virtual Master broadcasts references on.
SOURCE
Selects the source of the virtual master speed and position.
Enumerated Value : Source
0 : S RAMP
1 : FEEDBACK POSN
2 : REFERENCE ENCODR
3 : LINEAR RAMP
INPUT
Ramp input.
ACCELERATION
Sets the acceleration rate in units of percent per second², i.e. if the full speed of the machine is 1.25m/s then the acceleration
will be: 1.25 x 75.00% = 0.9375m/s²
DECELERATION
This functions in the same way as ACCELERATION above.

the virtual master output is derived from the INPUT parameter via an sramp function
the virtual master output is the motor shaft speed and position, unchanged
the virtual master output is the reference encoder speed and position, unchanged
the virtual master output is derived from the INPUT parameter, passed through a linear
ramp function
