I never put it on the scope to verify it. I bought one driver from Granite Devices and did some tests to verify it would work. They do not offer the new version with enough voltage yet that I am...

Winter is here and I am able to get back to my project for the Dynamyte conversion. I see that there has been an upgrade on the VSD-A. I purchased on of the drives to experiment with. The motors I...

Chris, Have you had any luck with the spindle portion of your retro fit. I have purchased and been testing the VSD from Granite Devices for the AC servos and I am almost to the solution. The next...

it happens as soon as I hit the arrow so I assume that it is the Variac not putting out ennough current. I have not built the power Supply as I want to make sure the VSD would work on my motors. I...

Com is set to ground. I found the problem last night....I did not set the jumper to SPI. Once I did that the motor turns. Now I think need to tweek the motor tuning. I am using Mach 3. When I...

On the CNC4PC BOB (model C10) I hooked the + step (pin 6 on VSD)to pin 2 on the BOB, + dir (pin 9 on VSD) to pin 3 on the BOB and both the -step and -dir (pin 7 and 10 on VSD) on the same comm on the...

I hooked up to my CNC4PC breakout board and am back to the steady green light. However, I can not get the motor to spin. I tried to turn the shaft by hand and it is under power. The driver needs to...

OK, I have the new encoder mounted and have been through all the tests. I have a steady green light on the drive. I hooked up the the Granite Device breakout board and kept getting a blinking green...

Ok. looks like I am going down the right track. I have ordered a new encoder as this one made by Mitsu. is a 12 VDC unit referred to as a "pickup unit". (This is a stand alone motor of the same...

According to Mitsu. particular motor I am doing my tests on (off of a mazak mill) has a 24 VDC encoder on it. I took it off tonight and will replace it with one from Automation Direct. Then I can...

I tried the torque step response and the motor will only spin about 1/4 turn. I can develop a nice graph per the instructions. How long should the motor spin in the torque test?

Do you think I will need the 15 VDC as well as the 5VDC? If I use the 15 VDC will it end up damaging the Drive?

Concerning the encoder issue, I have 5 VDC going to the encoder, how can I check the output? Also, the encoder has a 15 VDC input and a U+ U- V+ V- W+ W- ( in addition to the 5VD and A+ A- B+ B- Z+...

I was able to get back to this last night. I resaved followed the directions in the manual. The motor rotates slowly and very jerky (about 6 RPM). After the Motor Test, I get a message to check...

No the motor turns by hand. I can turn it by hand when I hit the test motor button on the Granite Devices tuning software. I check across L1,L2 L3 and I do not have any voltage going to the motor...

I have the solid led and the blinking led on the drive itself. I have no leds in the array of leds above the encoder plugin. The power supply is a Variac outputing 140 VAC which goes into the...

Does anyone out there have any experience hooking up Granite Devices VSD-S? I have it all done ( to one motor) but I do not seem to get any movement at all on the motor? I am using a Variac as a...

I agree with H.O. I am working on a Dyna Myte 4400M that was being thrown away. The only way I can justify spending money (with my wife) if the fact I did not have to pay a dime for the machine in...

Do you have a recommend encoder that you use in case I can not get the correct wiring information and I need to change out the encoders. I contacted Mitsubishi and I will post whatever they send me.

Woodturn, Just so I am clear, Does your machine have the HA40CS motors on the X and Y axis with the HA80CS on the Z?

Is there anyone is the Midwest US area that is using the Granite VSD-A's. I would appreciate talking to you concering this product. Should like this is a actual doable project. I have this great...

They are OSE5KN -6-12-108
Mitsubshi reports:

OSE - Optical type shaft encoder
5K - 5000 P/R
N - Special symbol
6 - output channels
12 - Shaft diameter
108 - Flange diameter

Ooops. Dyna Myte 4400M M3 controller The part numbers are Dyna numbers from their book. Sorry about that.

Hello,

It appears my DC power supply has died and it is only receiving 20 VAC from the Turret Interface board. The Interface board is getting 110 from that it requires so I am assuming the Turret...

Here is what I can find from Mitsubshi:

Motor HA40CS 3Phase
Input in 100% (kVA) 1.0
Input in 100% at 170V 3.4

Motor HA80CS 3 Phase
Input in 100% (kVA) 1.6
Input in 100% at 170V 5.4

Do you have access to the electrical specs & encoder details for the HA40CS and the HA80CS? I contacted Granite Devices on another thread concerning the compatibility question.

Thanks

I am looking into retrofitting a Dyna Myte 4400M mill. It has:

X-Y axis
HA40CS
Rated Torque
30.0 kg/cm at stall (2687 oz.in.)
27.2 kg/cm at 1000 RPM
24.4 kg/cm at 2000 RPM
Max. RPM 2000...

Do you know of anyone who has done this with the Granite Devices drives?

I was thinking of going with Mach3. All I would need is 3 new drives from Granite Devices and a breakout board. I still...

I have a 4400M and I really like what I read about the retrofitting. But, just so I understand, there is no way to retro with the AC servo drives....right?

That would be great. You can send them to [email protected].

How much was the battery anyway, Mine needs replacing and I have not gotten around to it.
