Setting the Transducer Counts per Motor Revolution for the 1394
You have to adjust the Transducer Counts per Motor Revolution
parameter when you use an external transducer to close the servo
position loop. This parameter is used to scale internal variables for
tuning the axis.
With the Axis Configuration edit window open, set the transducer
counts per motor revolution. To set the transducer counts per motor
revolution:
1. From the Configuration menu, select Drive/Motor 1394.
Note: If a GML Info window appears, note the information and select
OK.
2. Enter a value in the Transducer Counts/Mtr Rev field.
For Example: If the motor shaft to resolver package shaft gear ration
is 10:1 (every time the resolver package shaft makes one revolution,
the motor shaft makes ten.), enter 409.6. Please note that this example
is valid for single/dual packages that have a resolver element to input
package shaft gear ration of 1:1.
For Example: If the resolver package to resolver element shaft gear
ratio is 2.5:1 (every time the internal resolver element makes one
revolution, the resolver package shaft makes 2.5) and the motor shaft
to resolver package shaft is 10:1 (every time the resolver package
shaft makes one revolution the motor makes ten) enter ((4096/2.5) /
10) = 163.84.
3. Go to Selecting the Homing Procedure.
Selecting the Homing Procedure
With the Axis Configuration edit window open, set the homing
position. To set the homing position:
1. From the Configure menu, select Homing. The homing options
appear.
If the Ratio: Do this:
between the motor shaft and the
resolver package input shaft si 1:1 Enter 4096
between the motor shaft and the
resolver package input shaft is not
1:1 Adjust the value to compensate for
the ratio (refer to the examples for
more information).
