Hitachi VFD EtherCAT Parameter Settings
To set up the Hitachi VFD to be commanded by EtherCAT you will need to modify 2 parameters:
AA101 (Main Speed Source_M1) change from 1 (Term.[Ai1]) to 9 (Option-1)
AA111 (Run-cmd. Source_M1) change from 0 (Term.[FW]/[RV]) to 4 (Option-1)
You can also modify the fan settings with the below parameter.
bA-70 (Cooling fan ctrl) change from 0 (Always ON) to 2 (Temperature)
The RapidPath plugin controls (writes to) some parameters for operation. If you change the value of any of them, your change will be overwritten.
| Parameter |
| CC-01 |
| CC-02 |
| CC-06 |
| CC-07 |
This can be done automatically via Mach.
Go to Configure | Plugins | RapidPath - MachMotion:
Select the Other Devices tab, Click on the Hitachi VFD in the dropdown on the left and then select the Device Parameters at the bottom of the page:
From here you can click the Load from File button. Navigate to the Plugins/Dependencies/RapidPath/DriveConfig/Hitachi_VFD directory and select the file: Hitachi_Install_EtherCAT_I_O_device.drvprm.
Once it has loaded the parameter values, those which were updated, will be highlighted in green:
Click Write Changes button to save the updates to the drive.
You will need to recycle the drive for the change to the fan to take immediate effect.
