load: Command word: 011F LS data word: 09C4 0n3B Load Stop Mode (or Resume Decelerate Mode) Changes a Pulse Train output’s deceleration to stop the Ramp immediately when the Output Enable bit goes Off. The Ramp function must be enabled. Example: to set up a Pulse Train output for Stop Ramp (0002) operation on ch.1: Command word: 013B LS data word: 0002 The same command can be used to reset the output to Decelerate mode (the default) by entering the value 0001 in the LS data word. Example: reset the same Pulse Train output to Decelerate (0001) operation: Command word: 013B LS data word: 0001 13-26 VersaMax Modules, Power Supplies and Carriers User's Manual GFK-1504N 13 IC200MDD841 Mixed Module, 24 V DC Positive Logic Input 20 / Output 12 Point / (4) High-speed Counter, PWM, or Pulse Train Configurable Command Word (hex) Command Description 0n3C Load Acceleration Changes a Pulse Train output’s acceleration. The Ramp function must be enabled. Both acceleration and deceleration can be selected from the range of 10 p/s2 to 1,000,000 p/s2 . The default for both is 1,000,000. In the acceleration and deceleration commands, the data value is a 32-bit number. These are the ONLY Data Commands that should have any value other than 0 in the MS data word. Example: to change the acceleration rate of Pulse Train output 1 to 200,000 (30D40H), load: Command word: 013C LS data word: 0D40 MS data word: 0003 0n3D Load Deceleration Changes a Pulse Train output’s deceleration. The Ramp function must be enabled. Example: to change the deceleration rate of Pulse Train output 1 to 2,000 (700H), load: Command word: 013D LS data word: 700 0n3E Load Correction Sets the change (in microseconds) that should be applied to the duty cycle of a Pulse Train output to compensate for the slow turn-off time of the optical isolator circuit (default to 75µs). The range is 0 to 200 microseconds. Example: to change the duty cycle of Pulse Train output 1 to 100 (64H), load: Command word: 013E LS data word: 64 GFK-1504N Chapter 13 Mixed Discrete/High-Speed Counter Module 13-27 13 IC200MDD841 Mixed Module, 24 V DC Positive Logic Input 20 / Output 12 Point / (4) High-speed Counter, PWM, or Pulse Train Configurable Using the COMREQ Function to Send Data Commands The VersaMax PLC CPU can use the COMREQ function to send Data Commands to the High Speed Counter module. These commands are all 6 bytes in length. The command data must be placed in the correct order (in a command block) in CPU memory before the command is executed. Program logic should be set up to assure that the command is sent to the module once, not repeatedly. This function is effective only on counters that are enabled. Command Block The format for Data Commands is as follows: MSB LSB command word data word (LSW) where: n=counter 1-4 cc=subcommand code dd=data type 0n cc dd dd data word (MSW) dd dd The command block used to send Data Commands is composed of 10 words as follows. All values are hexadecimal unless otherwise indicated. Note that if the command block is not set up correctly, unexpected operation may occur. The command block can be placed in any word-oriented area of memory that is not reserved.
