Summary of operation

Read and display the command pulse and feedback pulse counter on the X-axis. The counter value can be cleared only when the axis is normally stopped (stopped without error). Read the counter value in a timer event.

Program code

cmdStr = "PX"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr)        ’Obtain the command pulse counter value on X-axis

OutplsX.Text = replyStr                                                        ’Display the command pulse counter value

cmdStr = "EX"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr)        ’Obtain the feedback pulse counter value on X-axis

FeedbackX.Text = replyStr                                                ‘Display the feedback counter value

cmdStr = "MSTX"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr)        ’Obtain the status value of X-axis

mStatusX.Text = replyStr                                                        ‘Display the status value for X-axis


Execute the above process repeatedly in the timer event


If mStatusX.Text = "0" Then                                                ‘Does X-axis stop normally?

cmdStr = "PX=0"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr)        ’X-axis command pulse counter clear

cmdStr = "EX=0"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr)        ’X-axis feedback pulse counter clear
