Step 4 - Selecting The Approach; Step 5 - Setting Up The Initialization Parameters - Delta Computer Systems TMC 188/40 Series Manual

Getting Started
The following example shows you how to initialize the WY registers. The values are the same as
those in the demo program.
To set up the WY registers:
1. Run TISOFT.
2. Put it in the ON-LINE mode.
3. Select CHART; select BLDCHT.
4. Enter WY201 - WY208 (or whatever WY registers you are going to use).
5. Select CHGVAL to set the values for the eight WY registers. The values you enter are the
addresses of the V Memory locations which the TMC 188/40 talks to (201, 251, etc. in the
demo program).
6. When you have entered all eight values (including the checksum), verify the P/C LED on the
TMC 188/40 panel is green.
NOTE: Once the TMC 188/40 finds a correct set of WY registers (including a valid checksum), it will
read them again unless reset. Changes in the WY registers will not take effect until the
188/40 is reset or the power is cycled.

Step 4 - Selecting the Approach

Once the WY registers are initialized, there are two methodss to get the TMC 188/40 running. The
first is to use DELTA's PC-based program called DCSMON. DCSMON provides a simple way for you
to get on-line without using a P/C ladder logic program. DCSMON talks directly to the TMC 188/40
by using the P/C's store and forward commands. Please refer to the DCSMON manual for help using
it.
The second method is for you to follow the steps outlined below. To help you start, an example
program is provided with DCSMON. The latest versions of this demo program are listed in filelist.txt
on the DCSMON disk. You can use it with the 525, 535, 545, and 555 controllers after the controller
type is specified using TISOFT.
TIP: Use Delta's DCSMON to help determine initialization parameters and operation. Also, Delta's
SSS/10 Servo System Simulator provides a simple way to test your program before connecting
the Motion Control Module to your system.

Step 5 - Setting Up the Initialization Parameters

When the TMC 188/40 Motion Control Module is first turned on, default values are used for the
initialization parameters. These values are there only to give the MCM so the present position can be
maintained. The parameters need to be changed to work optimally in your system. The P/C is
