Section 2: Overview of Product Operations
Each DSM314 axis
may be operated with the Follower Control Loop enabled or disabled:
Standard Mode (
Follower Control Loop
Axis Configuration = Disabled)
In Digital Standard mode, the module provides closed loop position, velocity, and torque
control for up to two GE Fanuc
α
or
β
Series servomotors on Axis 1 and Axis 2. Axis 3
can be used as an Analog servo axis or an Aux master axis.
In Analog Standard mode, the module provides closed loop position control for up to four
servomotors. When the DSM is used with analog servos, velocity and torque control
loops are closed in the servo amplifier, not in the DSM module.
For both digital and analog applications, user programming units can be adjusted by
configuring the ratio of User Units and Counts configuration parameters.
Jog, Move at
Velocity
and
Execute Motion Program
commands allow Standard mode to be used in a
wide variety of positioning applications.
Follower Mode (
Follower Control Loop
Axis Configuration = Enabled)
In Digital Follower mode, the module provides closed loop position, velocity, and torque
control for up to two GE Fanuc
α
or
β
Series servomotors on Axis 1 and Axis 2. Axis 3
can be used as an Analog servo axis or an Aux master axis.
In Analog Follower mode, the module provides closed loop position control for up to four
servomotors (one or two of the four available axes may instead be used as an Aux master
axis). When the DSM is used with analog servos, velocity and torque control loops are
closed in the servo amplifier, not in the DSM module.
In both digital and analog applications, the module provides the same features as
Standard mode including configurable User Units to Counts ratio.
In addition, a Master Axis position input can be configured. Each Follower axis tracks
the Master Axis input at a programmable (A: B) ratio. Motion caused by
Jog, Move at
Velocity
and
Execute Motion Program
commands can be combined with follower motion
generated by the master axis.
Follower options include:
•
Master Axis source configurable as Actual or Commanded Position from any other
axis
•
Master Source Select
%Q bit switches between two pre-configured Master Axis
sources
•
Acceleration Ramp to smoothly accelerate a slave axis until its position and velocity
synchronize to the master
•
Separate enable and disable follower trigger sources
Note that Winder mode is not supported in the DSM314. It is supported in the DSM302.
