Hitachi VFD EtherCAT Parameter Settings
This is duplicate documentation from the Hitachi P1 VFD installation manual. Please make all future updates to that documentation.
To set up the Hitachi VFD to be commanded by EtherCAT you will need to modify 2 parameters:
|
Parameter |
Description | Default Value | Desired Value |
|
AA101 |
Main Speed Source_M | 1 (Term.[Ai1]) | 9 (Option-1) |
| AA111 | Run-cmd. Source_M1 | 0 (Term.[FW]/[RV]) | 4 (Option-1) |
If there is a delayed safety relay (knob or switches on the front of the safety relay), you will need to set up the following:
(BOM Example:
)
- CA-03: 31 (Sets S3 input to fast stop)
- CA-23: 1 (Sets S3 input to Normally Closed)
- AC-126: 4 (Or to your fast stop deceleration time - match standard decel)
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.
