简介

注意: 本培训手册中仅包含必要的背景信息。 有关softMC硬件和软件系统的下载和更多信息，请使用Servotronix网站上提供的资源。

ControlStudio是基于PC的图形用户界面，用于softMC开发和测试控制和/或协调的运动应用程序。 ControlStudio包含编程编辑器，数据记录器，调试器和监视工具。 一旦应用程序完成，PC可以被移除，并且softMC控制器可以独立运行或在网络内运行。

softMC配置器是ControlStudio绑定的应用程序。配置器用于定义运动应用中要控制的轴和IO; 然后生成一组用于初始化softMC的程序和文件。

MC-Basic (Motion Control BASIC)是由Servotronix开发的用于softMC的专有编程语言。 它基于标准的BASIC编程语言，对多任务和运动控制功能进行了广泛的增强。

步骤

Initial Active OpMode = 8-Cyclic synchronous position

Physical Address = 1

Click Apply.

Link Drive to Axis = A1.

Click the Link arrow.

Note: For proper operation, Initial Active OpMode must be set to 8-Cyclic synchronous position

(7D) Configurator displays the Axis:A1 screen.

The screen has four tabs: General, Properties, Movement and Graph.

In the General tab, enter settings as shown below.

Axis Type = Rotary Gear

Length Units = Degrees (default)

Gear Ratio = 1.0

Note: A gear ratio value is usually in the range 10—160. When using a Servotronix Demo Kit, Gear Ratio value = 1.

(7E) Guidelines Most robotic applications are programmed in units of degree/second, that is, 360 deg = 1 revolution. Therefore:

6 deg/sec = 1 rpm

120 deg/sec = 20 rpm

360 deg/sec = 60 rpm

The instructions in this document use the following calculations and values, which are typical for a brushless DC motor:

Use the same value for both acceleration and deceleration. However, if the Load to Motor Inertia Ratio ratio is less than 10 (optimal LMJR value), a higher acceleration can be used.

(7F) In the Properties tab, click on the Limits bar to access Limit parameters.

Change the values of the following parameters:

Position Error Max = 10

Velocity Max = 30000

Acceleration Max = 900000

Deceleration Max = 900000

Jerk Max = 2700000

After typing in a value, be sure to press Enter.

(7G) Save Configurator project (EX01.mcfg)

(8) Define axis A2 configuration settings

Configurator online

(8A) Define the parameters for Axis A2 by repeating the steps in Step 7.

(11D) In the Movement tab, disable the axes

(11E) Save the Configurator project.

Exit Configurator

(12) Work with softMC controller via Terminal

ControlStudio online (12A) If softMC has been power cycled, this step is required. Otherwise, skip to Step12C. In the Terminal pane, enter the command reset all

Note: The command reset all does the following:

Removes all system variables and tasks from controller RAM.

Removes all files from controller RAM .

Runs the CONFIG.PRG task

(12B) If softMC has been power cycled, this step is required. Otherwise, skip to Step12C.

In the Terminal pane, enter the command load startprg.prg

Note: The command load startprg.prg loads all configuration data from controller Flash (non-volatile) memory to RAM. Data remains in Flash memory.

Look at the messages in the Message Log pane.

The system is now ready to receive commands.

(12C) In the Terminal pane, enable the axes.

Enable axis 1:

-->a1.en=1

Enable axis 2:

-->a2.en=1

Gently grasp the motor load disk and try to move them. Strong resistance indicates the motor is enabled.

(12D) Note: The Move executes a point-to-point move from the current position to the target position of a single axis or a group of axes.

Note: Use F3 as a shorcut to repeat last command entered

In the Terminal pane, execute Move commands, and observe the response of the motors.

Move A1 and A2 to absolute position PFB 0:

-->move a1 0 abs=1

-->move a2 0 abs=1

Move A1 and A2 to absolute position PFB 3600 (10 revolutions from 0):

-->move a1 3600 abs=1

-->move a2 3600 abs=1

Move A1 one revolution counterclockwise:

-->move a1 -360 abs=0

Move A2 two revolution clockwise:

-->move a2 720

Move A1 and A2 to absolute position PFB 7200 at different speeds:

-->move a1 7200 abs=1 vcruise=720

-->move a2 7200 abs=1 vcruise=240

(12E) Note: Jog moves the axis at a constant velocity.

Use the Stop command to stop a Jog motion.

In the Terminal pane, execute Jog commands, and observe the response of the motors:

-->jog a1 720

-->jog a2 240

Allow both motors to run simultaneously.

Then stop the motion:

-->stop a1

-->stop a2

Disable the axes:
