How to fit a Yaskawa Inverter as a replacement in the field
Yaskawa, Inverter, TB0417 Fitting_Yaskawa_Inverter_GA700-topright.jpg
The Yaskawa has a very similar outer body size to the Delta inverter. This means that it will fit into the same space that the Delta did. However, the hole centres are different. New holes will need to be drilled when first fitting a Yaskawa.
The Yaskawa is much taller than the Jaguar inverter. This may mean that the Yaskawa will not fit in the same space that the Jaguar did. We had the same problem when replacing Jaguar with Delta. There has been occasions in some of the older style ZX cabinets where the plastic trunking had to be re-routed to allow the room for the new inverter to fit.
This is a general diagram for cabling into the different machine types - more details for each machine will follow
When the inverter is fitted, the screen needs to be removed via the clip on the top. If you do not do this, the connector that is behind the screen can be bent out of place and the screen will not reconnect. The main cover that is at the front of the inverter needs to be removed with the screw at the bottom right. You then have to pinch either side of the inverter and lift the cover up.
You can then start wiring in cables from the original inverter setup as per table in the electrical drawing.
There will be some wiring that needs to be added. The table show all extra wiring that is needed for the inverter. The extra wiring will need to splice off existing cables in the electrical cabinet. The Yaskawa inverter needs more IO than the Jaguar. If there is a Delta fitted, you will find that most of the IO will already be in.
The Yaskawa inverter has also been programmed to monitor the temperature of the dump resistor. If the machine has a dump resistor with a thermal overload on it, this needs to be wired into the inverter. The alarm for this input is only in fault state when the input is high. This means if you do not have a thermal overload, leave the input terminal empty.
The Yaskawa inverter also has an output to say the spindle is at zero speed. This will need to be wired back into the main machine PLC or IO slices. This will then need a software update from Stuga.
· Timing issues on switching the double plunge configuration means that another IO channel is needed – OuB_InvDP (Y271). This output used to directly control the inverter, not the Y376, Y377, Y58, Y62
· Version 6.2514 or later needed
· Mapping required for Y271
· Increase C1-01 accel time on 50Hz to 0.3
· Increase C1-05 accel time on 300Hz to 0.3
· Wire S1 to Module B Output Slice channel 1 (Y63)
· Wire S2 to Module B Output Slice channel 2 (Y63)
· Wire S3 and S4 to Module B Output Slice Channel 3 and 4 (Y376)
· 59a to 0v
· 24v link across 3 other inputs
· Inverter fault direct output (bypass the useless link through the overload relay)
· Inverter reset wire to output slice
· Inverter at zero wire to input slice channel 7 (X308)
· Resistor fault not working correctly, leave disconnected STO??! Inverter powers off on estop, works ok, leave links in HC, H1,H2
· Double link the double plunge outputs (Y271) 0> Channel 3 and 4
· Link inverter reset (X308) -> Channel 7
· Link inverter zero
· Latest software version
· Ensure inverter alarm is correct sense
· Parameter Invert300hz=1
· Check inverter display changes to 300hz / 50 HS when spindles are selected
· The phase monitoring device is not needed any more, but it is inactive, so can be left in place.
· Remove the cable 127 connecting SIG to the Delta inverter
· 3 new wires required, Y63 (Inv_300), Y271(Inv_Dp) and X308 (Inv_Zero)
· Y63, Y271 and X308 will need mapping in TwinCAT3 and adding to IO Ref
· Parameter Invert300Hz needs to be true
· Latest Software needs to be added to sort timings and use of Y63, Y271 and X308

Electrical Highlights:
· Ensure 24v connected to M1 and M3
· Y271(OuB_InvDp) uses the existing cabling in S4, currently labelled Y377
o A link will need to be added up to S3, where there currently is a cable labelled Y376
· Using Y376 cable, remove the labelling and label as X308 (InA_InvZero)
o The other end of this currently goes to the beckhoff slice MC3B pin 15 (OU1). This now needs to be moved to pin 4 (IN4), and relabelled.
· A link wire between M4 and S8 needs to be added
· Remove Wire 60B (From Aux contact on F5 to RC1 on Delta Inverter). Not needed because Inverter OK signal does not need to be in series with F5 overload
· Remove wire 61B from Phase monitor to Delta MI6. Not needed because Yaskawa does phase monitoring internally
· 2 additional 24v control relays needed for interfacing TwinSafe to the STO inputs as per diagram

Electrical Highlights:
· To create space for the new inverter, remove the contactor and timer for delaying the drive switching (If they exist) – these are normally located under the old inverter. This switching was only necessary when a DOS PC was used, the contactor can be bypassed.
· The supply to the new inverter needs to be wired directly rather than via the estop contactor. The new drive has “STO” (Safe Torque Off) inputs that are wired through two 24v dc relays (supplied). This means when ESTOP is pressed, the drive does not power off, it goes into safe torque off mode. This is a much more reliable system than “crash” shutting off the inverter on estop.
· The phase monitoring device (if fitted) is not needed any more, but it is inactive, so can be left in place.
· The 50Hz relays for RY1 and RY4 should be removed and the wires RY1, RY4 wired directly to the inverter inputs S1 and S2. This removes the relays as a potential point of failure.
· Ensure 24v connected to MC, M1 and M3
· New cable for Y271(OuB_InvDp) from S3 and S4 (link), connect to Output channel 8 on 1st IO slice. Note: the SPDP wire (Y99) may be numbered Y58 and in the output channel 8. For consistency, make:
o Ou7 - SPDP – Y99
o Ou8 – Inv_DP – Y271
· New Cable X308 (InA_InvZero) from M2, connect to Input channel 7 on 4th IO slice.
· A link wire between M4 and S8 needs to be added
· 2 additional 24v control relays needed for interfacing Estop to the STO inputs as per diagram
· The Inverter OK signal (X27) should be wired directly from the inverter to the input slice – it is probably wired via the inverter overload relay auxiliary contact – this is now redundant and will cause confusion
· Remove the link SP to SC. This is for grounding an internal PSU that is not used
· Remove X99 wire, this was a feedback check to ensure the 50Hz relays had switched, no not required

Delete any reference to IS300 input
Ensure the alarms are set for each individual spindle:
41,MOVL,False,SPIN1,True,0,4,Spindle 1 Alarm,True,False
42,MOVL,False,SPIN2,True,0,4,Spindle 2 Alarm,True,False

45,MOVL,False,SPIN5,True,0,4,Spindle 5 Alarm,True,False
46,MOVL,False,SPIN6,True,0,4,Spindle 6 Alarm,True,False
The MOVL should be High when the inverter is OK.
Remove any alarms relating to IS300 input
Version 3.9994 or higher should be added, which will also warrant a front end upgrade to the latest version
· Ensure inverter alarm is correct sense
· Parameter Invert300hz=1
· Parameter InverterOKHigh=1
· Parameter psInvDecel300Hz=400
· Check inverter display changes to 300hz / 50 HS when spindles are selected
Download and install Yaskawa DriveWizard
Ensure the Yaskawa USB is connected to the PC
Find the COM port it is connected to (use Device Manager Ports) – this is usually COM3. If there are other connections on the same COM port, right click and uninstall them (EDG). This will need a reboot after uninstalling
Using DriveWizard, or via the physical keypad on the device, change the following parameters
No | Description | New Value |
C1-01 | 50Hz Accel Time | 0.5 |
C1-02 | 50Hz Decel Time | 0.5 |
C1-05 | 300Hz Accel Time | 0.4 |
C1-06 | 300Hz Decel Time | 0.4 |
Electrical Highlights:
· The inverter will need to be located on the side of the cabinet, as the Yaskawa is taller than the VXR
· The supply to the new inverter needs to be wired directly rather than via the estop contactor. The new drive has “STO” (Safe Torque Off) inputs that are wired through two 24v dc relays (supplied). This means when ESTOP is pressed, the drive does not power off, it goes into safe torque off mode. This is a much more reliable system than “crash” shutting off the inverter on estop.
· The phase monitoring device (if fitted) is not needed any more, but it is inactive, so can be left in place.
· Ensure 24v connected to MC, M1 and M3
· The Zx3 and Microline have a set of switchover contactors to select 50Hz (Mains) or 300Hz (Inverter). Therefore, the inverter does not need to do the 50 / 300Hz switching as on later machine models.
· New cable for Y271 (InvDp) from S3 and S4 (link), connect Output channel 5 on 2nd Output slice (labelled 5)
·
New Cable X308 (InA_InvZero) from M2, connect to input channel 8 on 1st IO slice (labelled 8)..
· A link wire between M4 and S8 needs to be added
· 2 additional 24v control relays needed for interfacing Estop to the STO inputs as per diagram
· The Inverter OK signal (X48) should be wired directly from the inverter to the input slice – it is probably wired via the inverter overload relay auxiliary contact – this is now redundant and will cause confusion
· Remove the link SP to SC. This is for grounding an internal PSU that is not used
· Inverter Reset function is done with Y34 SRST. The VXR inverter was powered off on estop, so did not need a reset function. Tag in to a Y34 cable on any servo drive (PL4 pin 2)

1. Select a spindle 1 or 2
2. Set HZ50 to run
3. Set Hz50 off
1. Select a spindle 3 to 7
2. Set HZ300
3. Set SMOT to accellerate
4. Ensure InZRO goes off and InvOK stays on
5. Reset SMOT to decelerate
6. Reset HZ300
7. Reset Spindle
Same as single, but select double plunge spindles and set InvDP to tell inverter to double the output power en none 0
