Page 5: Introduction
1. Introduction ACE-SXC is a stepper controller motion product. Communication to the ACE-SXC can be established over USB. It is also possible to download a standalone program to the device and have it run independent of a host. Windows and Linux drivers, as well as a sample source code, are available to aid you in your software development. -

Page 15: Communication Interface
All USB communication will be down using an ASCII command protocol. 5.1.1. Typical USB Setup The ACE-SXC can be connected to a PC directly via USB or through a USB hub. All USB cables should have a noise suppression choke to avoid communication loss or interruption. - Page 16 64 characters.

Page 18: General Operation Overview
USB. Standalone commands are used when writing a standalone program onto the ACE-SXC. 6.1. Motion Profile By default, the ACE-SXC uses a trapezoidal velocity profile as shown in Figure 6.0. Figure 6.0 Once a typical move is issued, the axis will immediately start moving at the low speed setting and accelerate to the high speed. -
Page 19: Motor Position
6.2. Motor Position The ACE-SXC has a 32 bit signed step position counter. Range of the position counter is from –2,147,483,648 to 2,147,483,647. Motor position can be read using the ASCII command PX, which returns the pulse position. To manually set/get the position of the motor, use the PX=[value] command. -

Instead, an error response is returned. See table 9.1 for details on error responses. The ACE-SXC has three different homing routines. The syntax for the home command in ASCII and standalone mode can be found below. ACE-SXC Manual page 20 rev 2.05... -
Page 21: Mode 1: Home Input Only (High Speed Only)
A. Issuing the command starts the motor from low speed and accelerates to high speed in search of the home input. B. As soon as the home input is triggered, the position counter is reset to zero and the motor stops. ASCII H[+/-] Standalone HOMEX[+/-] ACE-SXC Manual page 21 rev 2.05... -
Page 22: Mode 2: Limit Only
C. The motor will start moving in the opposite direction. First accelerating to high speed, maintaining speed, and then decelerating. D. Once position counter has reached zero, the motor stops. L[+/-] ASCII Standalone LHOMEX[+/-] ACE-SXC Manual page 22 rev 2.05... -

CLR command to clear the error before issuing any more move commands. 6.10. Digital Inputs / Outputs / Configuration Button The ACE-SXC module comes with three digital inputs and two digital outputs. If the limit/alarm function is disabled, up to eight inputs can be used as general purpose inputs. -
Page 26: Configuration Button
Standalone 6.12. Communication Time-Out Watchdog ACE-SXC allows for the user to trigger an alarm if the master has not communicated with the device for a set period of time. When an alarm is triggered, bit 10 of the MST parameter is turned on. The time-out value is set by the TOC command. -
Page 27: Standalone Program Specification
6.13. Standalone Program Specification Standalone programming allows the controller to execute a user defined program that is stored in the internal memory of the ACE-SXC. The standalone program can be run independently of USB communication or while communication is still active. -
Page 28: Standalone Subroutines
[0-1274]. 6.13.4. Standalone Subroutines The ACE-SXC has the capabilities of using up to 32 separate subroutines. Subroutines are typically used to perform functions that are repeated throughout the operation of the standalone program. Note that subroutines can be shared by both standalone programs. -

Method #2 uses the configuration button on the ACE-SXC controller to download the driver parameters. On the ACE-SXC controller, the driver type needs to be stored to flash so that when the button configuration is used, the correct driver configuration is performed. - Page 41 Once the correct driver type is selected and the driver parameter values are stored to flash memory, driver parameters can be downloaded from ACE-SXC to DMX-K-DRV without the use of Windows PC using the configuration button on the ACE-SXC. To configure the driver through the configuration button, follow the steps below.
