HITACHI P1 VFD Installation

There are 3 different ways a Hitachi VFD may be connected to MachMotion control: Ethercat, TCP
Modbus, or Hardwired. Use the following procedure to determine which method your VFD uses.
Then in each section of the manual go to that control method for information on how to program or
connect it.
On the menu bar of the MachMotion software, click Configure -> Control, then select theOutput
Signalstab.
Scroll down about 2/3s the list to the Spindle section. The Device that is selected for Spindle Fwd
and / or Spindle Rev shows how the spindle is controlled. Use the pictures below to identify which
method is used.
For a hardwired VFD, it could be controlled through a Beckhoff Device OR an Apollo III.
Control Cable: The VFD Control cable is the green Ethernet cable that runs from the Yaskawa VFD
to the Control PC as shown in Figure 1. Or if you have an Apollo III motion controller, connect the
VFD control cable into Ethernet 1 Port on the Apollo III.

(Figure 1 Ethernet Connection to Control PC)
Spindle Motor: Connect your spindle motor to the terminals labeled U/T1,V/T2, and W/T3 as
shown in Figure 2. If your spindle moves the wrong direction when you turn it on, just swap any
three of the (U,V,W) leads.
(Figure 2 Spindle Motor Connections)
Brake Resistor: Connect your brake resistor by placing the two wires on the RB and P terminals
as shown in Figure 3.
(Note: If needed to extend the wires use High Temp rated wire.)
Mount Resistor:Mount the resistor to the cabinet. Wire as shown in Figure 3.

Modbus Installation

To modify the IP address follow these steps:
1. F1 (menu)
2. Select 01 Scroll modewith the Center button
3. Press the Down Arrow multiple times until you highlight o:Option Card
4. Select o:Option Card with the Center button
5. Press F2 (Next Gr) multiple time until you get to the group oL-01 IPv4 IP address
6. Press the Down Arrow multiple times until you highlight oL-03 IPv4 IP address

9. Press F2 (Save)
10. Repeat steps 6 to 9 to set the remaining address groups
Before the Control can connect to the VFD these parameters need to be set. On default you should
only need to set the ones in bold.
Parameters Description Default Range

To program the VFD you will need to utilize the Parameters. Follow the next few steps to find the
Hitachi parameters.
Setup the IP Address
Open the Configurable Parameters

Navigate to theService Page->Maintenance Pageand click onInterface Config
While in the Parameters Type "Hitachi" in the search field as shown in Figure 5. This will populate
the parameters for the Hitachi P1 VFD as shown below).

(Figure 5 Default Parameters)
For a main spindle, set Control Source to Mach and Modbus Control Enabled to Yes. For any
other spindle like a grind wheel, regulating wheel, or sub spindle, set Control Source to Auxiliary
and Modbus Control Enabled to Yes.
To set up the Hitachi VFD to be commanded by EtherCAT you will need to modify 2 parameters:
Enable the VFD

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:
The RapidPath plugin controls (writes to) some parameters for operation. If you change the
value of any of them, your change will be overwritten.
This can be done automatically via Mach.

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.

To be able to program the Hitachi VFD you will either need to change the parameters physically on
the VFD or with the Hitachi ProDrive Next software.

the programming.
By default from Hitachi, the AA101 and AA111 parameters are setup correctly:
Parameter Description Default Value Desired Value
AA101 Main Speed Source_M 1 (Term.[Ai1]) 1
AA111 Run-cmd. Source_M1 0 (Term.[FW]/[RV])0

Find your motor nameplate and enter in the parameters based on the table below.
If you cannot locate the motor’s base frequency, the name plate should tell you how many poles
there are on the motor. You can also call the motor manufacturer to figure out the number of poles.
Using the motor’s maximum RPM and its number of poles, you can calculate the base frequency
with the formula below:
Base Frequency = Rated RPM * Number of Poles / 120
Max Frequency = Max RPM * Number of Poles / 120
Parameters Description Default Range
AC120 Motor Accel. Time 4 Seconds 0.0 to 3600.0 Seconds
AC122 Motor Decel. Time 3 Seconds 0.0 to 3600.0 Seconds

You can also modify the fan settings with this parameter.

If you want to command your spindle motor or grinding wheel to go faster than the base frequency,
command the spindle to go max RPM and use a tachometer to measure the speed. Then use the
following formula to calculate your new Max Output Frequency (Hb105):
Desired Max RPM * Current Max Frequency / Current Max RPM = New Max Frequency
For example, if your Current Max Frequency is 60 and you measure the spindle runs 1030 RPM but
you actually want it to go 1515 RPM, calculate your new Max Frequency as follows:
1515 * 60 / 1030=88 Hz.
Make sure to recalibrate your RPM feedback and your spindle speed as both shown below.
Overspeed a Motor
Calibrate Spindle Speed

If your P1 is setup as a Mach spindle (under MachMotion Parameters), click on Configure -> Control
at top of the Mach screen. Then select the "Spindle" tab shown in Figure 7. Set your max spindle
RPM for each spindle range here.
(Figure 7 Spindle Tab)
If your VFD is enabled as an Auxiliary spindle (under MachMotion Parameters), set the Auxiliary
Control Max RPM to the max RPM of the motor.

If your VFD is enabled as a Mach spindle (and there can only be one enabled at a time), follow the
procedure below.
You will need to scale your emulated RPM feedback in the Mach software. Calculate your feedback
ratio as follows:
Max Spindle RPM / 3600 = Feedback Ratio
Then while the control is disabled follow the next few steps:
Step 1: Click on Configure -> Control at top of the Mach screen. Then select the "Spindle" tab
shown in Figure 7.
Calibrate RPM Feedback

(Figure 7 Spindle Tab)
Step 2: Enter in the value you calculated in FeedBack Ratio from the calculation you have done for
Spindle Gear 1 as shown in Figure 8.

(Figure 8 Enter Feedback Ratio)
If you were to get an alarm on the VFD you will receive a message on the computer screen from
the Global Message System. In the description of the alarm it will describe the necessary steps to
try to resolve the alarm.
To test any modbus VFD, review the following items to confirm it is setup correctly:
Troubleshooting
Alarms
Setup Verification

Does the VFD run the spindle? The VFD RUN light should be on solid when it is up to speed. If it
isn't, the VFD is not programmed correctly.
Does the RPM change when you change the spindle speed on the control?
Does the VFD go both directions?
If you disconnect the VFD control cable does the control time out with a VFD Disconnected Error?
Is the RPM feedback correct?
Does up to speed and at speed work correctly inside the control?
Make sure the VFD is powered all the time. Otherwise the VFD will not connect correctly.
Wire the Estop circuit as shown below:
