Yaskawa Modbus VFD Using Inputs for General Use


In the VFD we need to set parameters H1-01 to H1-06 to 000F to make them not used in the drive so we can monitor them.


Reboot the VFD after changing the H1 parameters

Next in Mach we need to add a new Modbus function under the Yaskawa-V1000-MON-x connection
