31 Direct mode is used to directly control the motion for real time movemen\ ts through serial communication. The DPE25601 has 40 commands which are easy to remember for direct movem\ ent of a step motor. COM Port Settings Baud Rate: 38400 Parity: None Data Bits: 8 Stop Bits: 1 Flow Control: Xon/Xoff Unit Selection In order to select a unit the @ command followed by 0 (address of the u\ nit) must be sent. NOTE: There should be no spaces between the @ and address select. How to select the unit: @0 (Unit is selected) @1 (Unit is selected) @29 (Unit 29 is selected) How to get a response from the unit: @0$ (Carriage Return) After the $ command, the DPE25601 will return a SMC60 + the current revi\ sion number. Note: In direct talk mode each command is followed by a carriage return.\ The unit communicates in half duplex mode, therefore proper setup of hyper terminal is necessary to view characters, if characters are to be echoed back to the screen. Instructions All instructions require that no spaces be sent between the command and the parameter followed by a carriage return. @0 not @ 0 correct: @0 (carriage return) incorrect: @0 (carriage return) Section 5: Direct Talk Mode Command Summary: A - Acceleration/Deceleration B - Base Speed C - Steps Between Outputs D - 1 st Output on the Fly Position EA - Encoder Auto Correct Enabled ED - Encoder Delay EM - Encoder Motor Ratio ER - Encoder Retries ET - Encoder reset EW - Encoder Window G - Go Number of Steps H - Home I - Read Inputs J - Fast Jog Speed M - Max Speed N - Number of Steps O - Set Outputs P - Absolute Position S - Go Slew T - Motor Current Enabled V - Verify Z - Position ! - Error Codes Register $ - Versions Number % - Verify ‘ - Index on the Fly Enabled ( - Output on the Fly Enabled + - Clockwise Direction , - Stop Soft - - Counterclockwise Direction . - Stop Hard / - Thumbwheel Enabled : - Analog Position Enabled ; - Analog Speed Enabled [ - Analog Speed Lower Limit ] - Analog Speed Upper Limit ^ - Number of Outputs { - Analog Position Lower Limit } - Analog Position Upper Limit ~ - Set Address of DPE25601 August 2012L010199

The higher the value, the faster the motor acceleration. Range: 100 - 9,999,999 B - Base Speed Format: B[value] Description: This command sets the base (start) speed for motion. This value must be set before motion begins and be less then the maximum speed and fast jog\ speed. Range: 1 - 5000 C - Number of Steps Between Outputs During Output on the Fly Format: C[value] Description: This command sets the number of steps between when output 1 turns on during an output on the fly move. If only one output turn on is needed, set this value to 0. This command is used in conjunction with the output on the fly enabled “(“ command. Range: 0 - 65535 D - 1st Output on the Fly Position Format: D[value] Description: This command sets the position at which output 1 will turn on during an output on the fly move. This command is used in conjunction with the output on the fly enabled “(“ command. Range: 0 - 65535 EA - Encoder Autocorrect Enabled Format: EA[0 or 1] Description: This command will either enable or disable the encoder auto correct func- tion. To enable the function use a 1, to disable the function use a 0. When this function is enabled, the relative register is used to calculate the encoder position, therefo\ re before the next move is made, the relative register needs to be set. This command is used in con- junction with the encoder delay “ED”, encoder ratio “EM”, encoder retries “ER” and encoder window “EW” commands. August 2012L010199
33 ED - Encoder Delay Format: ED[value] Description: This command sets the wait time a specified number of milliseconds after a relative index or absolute move is finished, before reading the encoder.
