GFK-1742A Chapter 4 Configuration 4-21
4
5.25 Cam Master Source.
This configuration item is unused in the present DSM314 firmware.
5.26 Follower Control Loop.
When this configuration item is set to Enabled, the servo axis will
follow a master axis input in addition to the standard internally generated motion functions.
Default: Disabled
5.27 Ratio A Value and Ratio B Value
. (Follower Control Loop must be Enabled) The A over
B ratio sets the follower slave/master gear ratio.
A * Master Reference Counts
Follower Axis Motion (counts) =
B
The range for A is –32,768 to +32,767 and B is 1 to +32,767. When A is negative, the
slave axis will move in the opposite direction from the master. The DSM firmware
supports A/B slave/master follower ratios in the ranges of 32:1 to 1:10,000. Default: 1:1.
5.28 Follower Master Source 1.
(Follower Control Loop must be Enabled) Configures follower
Master Axis Source 1. Allowed choices are Commanded or Actual Position for any of the 4 axes
(as long as it’s a configured axis). Follower Master Source 1 is active when the
Follower Master
Source Select
%Q bit is OFF.
Cmd Position or Actual Position of a slave axis should not be selected as a master source for
that axis.
If an unconfigured axis is selected for Follower Master Source 1, it will be ignored.
Default: None. Refer to Chapter 8 for information on follower mode.
5.29 Follower Master Source 2.
(Follower Control Loop must be Enabled) Configures follower
Master Axis Source 2. Allowed choices are Commanded or Actual Position for any of the 4 axes
(as long as it’s a configured axis). Follower Source 2 is active when the
Follower Master Source
Select
%Q bit is ON.
Cmd Position or Actual Position of a slave axis should not be selected as a master source for
that axis.
If an unconfigured axis is selected for Follower Master Source 2, it will be ignored.
Default: None. Refer to Chapter 8 for information on follower mode.
5.30 Follower Enable Trigger
.
Follower Enable Trigger Input. Selects the control bit, CTL01-
CTL32, to be used as the Follower Enable trigger input. The follower axis is enabled when the
selected trigger input transitions ON
and
the
Enable Follower
%Q bit is also ON. After Follower
is enabled, the PLC
Enable Follower
%Q bit and an optional Follower Disable trigger bit controls
the active state of the following function. None means the follower axis is enabled only by the
Enable Follower
%Q bit. Default: None.
5.31 Follower Disable Trigger.
Follower Disable Trigger Input. Selects the control bit, CTL01-
CTL32, to be used as the Follower Disable trigger input. The trigger input is tested only when the
Enable Follower
%Q bit is ON. When the
Enable Follower
%Q bit is ON, an OFF to ON
transition of the trigger bit will disable the follower. Turning OFF the
Enable Follower
%Q bit
immediately disables the follower, regardless of the disable trigger configuration. Default: None.
5.32 Follower Disable Action.
Stop means the follower will immediately decelerate to zero
velocity at the configured Follower Ramp Acceleration rate. Inc Position means the follower will
continue at its present velocity, then decelerate and stop after a specified distance has elapsed. The
incremental distance is specified in a parameter register for each axis:
P227 = Axis 1 Incremental distance
