Motor Status and Commands
The DMX-J-SA module allows for motor status monitoring and control through various commands. The MST command provides motor status, with specific bits indicating conditions such as constant speed, acceleration, deceleration, and limit errors. Limit errors must be cleared using the CLR command before further movement commands can be issued.

Digital Inputs and Outputs
The module includes two digital inputs and outputs. Digital inputs can be read using the DI command, and outputs can be controlled with the DO command. Inputs are active high, while outputs are active low. Initial states can be set using DOBOOT and EOBOOT registers.

Motor Power and Current Settings
Motor power is controlled via the EO command, and initial states can be set with EOBOOT. The module supports run and idle current settings, adjustable between 100mA and 2000mA. Idle current can be set to 0 to disable the motor during idle.

Standalone Language Specification
- Comments: Use ';' for comments. Each comment must be on its own line.
- Motion Commands: Includes commands like ABORTX, ABS, ACC, DELAY, DI, DO, ECLEARX, EO, GOSUB, HLHOMEX, HSPD, IF, INC, JOGX, LSPD, MSTX, PX, STOPX, STORE, SUB, TOC, V[0-49], WAITX, WHILE, and X.
Example Standalone Programs
- Program 1: Sets speed and moves motor to 1000 and back to 0.
- Program 2: Moves motor back and forth indefinitely between 1000 and 0.
- Program 3: Moves motor back and forth 10 times between 1000 and 0.
- Program 4: Moves motor back and forth between 1000 and 0 if digital input 1 is on.
- Program 5: Uses a subroutine to increment motor by 1000 when DI1 rising edge is detected.
Standalone Example Program 6 – Single Thread
- Task: Control motor movement based on digital inputs. Move to specific positions (1000, 2000, 3000) or home the motor in a negative direction using digital inputs 1, 2, 3, and 5 respectively. Use digital output 1 to indicate motor status.
- Specifications: High speed set to 20000 pulses/sec, low speed to 1000 pulses/sec, and acceleration to 300 msec.
- Procedure: A continuous loop checks digital inputs and moves the motor accordingly. Motor status is monitored and indicated via digital output.
Standalone Example Program 7 – Multi Thread
- Task: Program 0 moves the motor between positions 0 and 1000. Program 1 controls Program 0 using digital inputs.
- Specifications: High speed set to 20000 pps, low speed to 500 pps, and acceleration to 500 ms.
- Procedure: Program 0 runs a continuous loop for motor movement. Program 1 uses digital input 1 to start or stop Program 0.
Standalone Example Program 8 – Multi Thread
- Task: Program 0 moves the motor between positions 0 and 1000. Program 1 monitors communication time-out and manages motor operation accordingly.
- Specifications: High speed set to 1000 pps, low speed to 500 pps, acceleration to 500 ms, and time-out counter alarm set to 5 seconds.
- Procedure: Program 0 continuously moves the motor. Program 1 checks for time-out alarms, stops all motion, and re-enables Program 0 after a 3-second delay if an error occurs.
