11.3.4 Drive Test Commands

Drive test commands can be used to test the communications between the ETH-100 and your ASD. To run the ASD connected to the currently selected channel, click “Run” and submit a valid frequency command in the “FC” field. Clicking “Run” writes a value of 0xC400 to ASD register 0xFA00 (communication command). Submitting a valid frequency command writes that value to ASD register 0xFA01 (communication frequency command). Note that the “FC” field expects floating-point values; entering “53.43” will send a frequency command of 53.43 Hz to the drive.

Note that if you run the ASD from the embedded web server, bits #15 and #14 of the ASD’s communication command register (0xFA00) are set, which indicates “communication channel priority” to the drive. Local control of the drive will therefore be disabled until you click ”Stop”, which writes a value of 0x0000 to ASD register 0xFA00.
