Summary of operation

Change the X-axis speed at 50,000 pps to 70,000 pps during motion.

Program code

cmdStr = "LSPDX=1000"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr) ‘Starting speed of X axis set to 500 pps

cmdStr = "HSPDX=50000"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr) ‘Moving speed of X axis set to 50,000 pps

---omitted steps---

cmdStr = "JX−"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr) ’Start moving in the − direction

cmdStr = "SSPDM=2"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr) ‘Double the speed range

cmdStr = "SSPD=70000"

result = SendReceiveCommanderHID(devHandle, cmdStr, replyStr) ‘Update speed to 70,000 pps
