No 5V. No light.

No light that I have seen. I'll try the top 2 red wires to see it there is 5 V. Thanks

Hello; Thought I'd throw this out there to see if anyone has run across this:
We were getting blue screens and Real Time errors so I thought I'd try a new Hard Drive. Bought one and was trying to...

Yes - Typo. PSR4/5 NOT the VFS5

Ok; First of - Mike, you were right on a couple of things; Both X an Y were the 10300s and I should have swapped the drives to motors. Although the motor did need work it did not solve the...

Mallardfizz, Mike, you were correct - Problem was the VFS5. Swapping it did the trick. Again the symptom was that the spindle would not go from 0 to anything over 300 unless it was slowly stepped...

Mike: Thanks for the reply and I believe that you an Mallardfizz are correct. I went through the post on the PM site and found a nearly identical issue. I will try and post a pic of the scope...

I put in nearly 30 hours into this problem this weekend and last night. Got MotionLink Plus onto the drive and had the Err 14 Power Bus on the history. Pulled the 1250 spindle drive and it was...

OK: Finally getting somewhere on this one; Motor tested good static but got very hot after about 1 minute of running; bearings or clearance issue. Waiting for its return to test on the drive (off...

I checked supply voltage as we stepped it up and it dropped to 275VDC at one point but had stabilized before it faulted at 1100rpm so I'm still leaning towards the drive and not the power supply. I...

Mallardfizz; Thanks for the reply and advice. I Checked the DC volts and did not see any dips or spikes but I will watch it as fault happens to double check. Fault light came on the VFS5 first...

Well my backup Arrow 1000 took a dump while waiting for the X motor to come back on the Arrow 1250C. The "Spindle Drive Not Responding" error came up with the Spindle Drive faulting out when...

Example:

Mike; Thanks for the response. Motor is out to be tested. Cable was checked using Fluke Insulation meter set at 250V. I was thinking if I knew the amperage out of the drive I could see if it it...

First off thanks in advance for any response to this problem. I think I know the answer but wanted to run this through what really is the best forum on this machine on the net.
This is an Arrow...

E Stop is dual contact but both the 100V and the 24V were working. 100V makes it to terminals 3 and 4 on the velocity control unit when the EMG and PRDY I/O relays are make but that is not what...

Thanks for the reply: I'll check for the dual circuit Estop. I pulled the X axis micro switches off the machine and checked them and they are OK. The 100V between 3 & 4 are what energize the MCC...

STLK (100.1) - All NO contact diagnostic bits show 0 and the 2 NC show 1. But 101.1 = 1
So no luck there.
Looking at an old 6T Fanuc Maint. manual with a flow diagram it shows after ROM check (I...

Al; thanks for the reply. 700 thru 822 are all 0 except for the 701.5. It's like it never got past that point. The STLK (100.1) rung shows 2 paths and 5 contacts. They are for turret indexing>...

Alright: I need some expert advice. I have a 1984 Citizen L16 with a 3T (A?) control with 30M series servo control that is kicking my butt.
I am not an expert but I have the ability to read...
