RMC100 and RMCWin User Manual
2-2
users must use raw transducer counts. Delta’s motion controllers provide a conversion between
raw transducer counts and user-definable position units.
Defining position units achieves the following two purposes:
The mapping between raw transducer counts and position units is defined. This involves at
least one scale term, and in some cases an offset.
Select the range of valid 16-bit positions. Users can use unsigned positions (0-65535),
signed positions (-32768 to 32767), or any other 16-bit range from -65536 to 65535.
The methods used for defining position units differ between transducer types in order to fit the
interface most efficiently. Refer to the appropriate section or sections below:
MDT Scaling
SSI Scaling
Quadrature with Analog Output Scaling
Quadrature with Stepper Output Scaling
Analog Transducer Scaling
7. Set the Extend and Retract Limits of Each Axis
Note: This step should be skipped for rotational axes, such as many applications of quadrature
and stepper axes.
The RMC has software-enforced Extend and Retract Limits. This procedure describes setting
these limits by moving the axis to each limit and entering the appropriate value in each field.
Repeat the following steps for each axis:
A. Using one of the following methods, move the axis to the extend limit:
Use a control box (diddle box) that can electrically drive the valve or motor.
Manually position the motor or cylinder.
Use the Drive Test procedure described in step 5 above.
B. In RMCWin, enter the value in the Actual Position field for the axis into the axis’s Extend
Limit parameter.
C. Using any of the above three methods, move the axis to the retract limit.
D. In RMCWin, enter the value in the Actual Position field for the axis into the axis’s Retract
Limit parameter.
8. Tune Each Axis
Note: We strongly recommend using RMCWin to configure, tune, and troubleshoot the system.
Refer to Using Graphs of Axis Moves for information about creating plots of moves, which are
very useful for tuning and diagnostics.
The next step is to tune the position, pressure, or speed control of each axis. Refer to the following
