Re: Triac stepper motor voltage/amperage

From my notes, the parker SD drives were set at 2A for X and Y, with Z running at 3A. I thought I had the motor part numbers somewhere, along with the datasheets, but I can't find them. However I'm sure they were ran very conservatively. I do have my voltage calcs, which puts optimum voltage for X&Y...

Re: Triac Spindle stopped working

What fuse have you checked?

Depending on the exact setup, there is likely to a main power supply fuse (which should be OK as the control rack is powered), then another DIN rail mounted fuse just for the spindle, then there could be another fuse on the actual speed controller itself.

BT35 to BT30 Conversion parts?

Given the ever increasing rarity of BT35 tooling, I'm wondering what would be needed to convert from a BT35 spindle, to a BT30 spindle. Comparing the Triac parts list (I can only find a parts list for the ATC spindle), to the diagram/parts for the VMC spindle ( http://www.denfordata.com/bb/viewtopic...

Re: Sprint 400 10v input & grounding

It depends on your BOB.

Better ones will have the 0-10V circuitry isolated, provided you use an isolated supply (usually requires 12V), which is easily done with a DC to DC isolating supply.
And some will have an isolating supply on board.

Have you got a link to the BOB you're using?

Re: Wanted - Computer/Control mounting arm for Triac/Cyclone

My Cyclone never came with one, and now that I've nearly got a new control panel made for the Triac, I'd quite like to make one for the Cyclone, rather than just have a computer sat on top.

I can make one, but I was hoping somebody would have one lying around to save me the hassle.

Wanted - Computer/Control mounting arm for Triac/Cyclone

I'm looking for the mounting bracket/arm as used on Triacs and Cyclones (plus I'm sure other machines), as per the photos attached.

Re: Triac spindle stalled, now won't start!

I've not currently got a feeds and speeds calc installed to calculate the required spindle torque, however I suspect that size cutter will be pushing the limits of the spindle. You have to remember, if the spindle is rated at 1kw at 3000RPM, then at 800RPM, you've only got around 260w of power at 80...

Re: Triac spindle stalled, now won't start!

Next step would be to do some testing for power with everything powered up. Start with the basics. With the cabinet open, turn the power on, then activate the spindle. Check that there is power on both sides of the main fuses, just to rule out any faulty fuse holders. Next check for power at the spi...

Re: Triac spindle stalled, now won't start!

Have you tested the fuses with a multimeter, or just visually?

Have you tested the fuse on the spindle drive?

Do you hear a click when you try turning the spindle on?

Re: Brauer/Brower unit won't retract and leaks oil. Help pls

It could be a custom seal.

I'd think the best place to try would be somewhere that overhauls/repairs hydraulic rams.

Re: triac atc

Having just checked the first Triac brochure I've found, the spindle was rated at 1HP (I think some were lower, and some higher). So going by the KBIC manual (http://www.kbelectronics.com/manuals/kbic_manual.pdf - page 11), you need the resistor for 1hp on 180VDC, which should be part number 9841.

Moray, Tripping of the RCD may not be a fault in the equipment but a fault in the RCD.

Re: triac atc

If they are field wires, then you'll need to connect them to the field output from the KBIC.

Which if the wires weren't connected before, makes me suspect they're not really field wires.

Are there any model numbers on the motor?

Re: triac atc

IIRC early triacs did have spindle orientation, along with drive dogs for the toolholder, however they were dropped from later models to simplify the design, as they weren't really needed due to the motor not being able to produce enough torque to overcome the self locking taper. Some did also have ...

Re: triac atc

I think you've not wired the motor correctly. What happens if you only connect the two thickest wires to the KBIC? The main reason I fitted a new motor, was the original one was stuttering at higher speeds, and causing the main RCD in the workshop to trip. Rather than spend money trying a new drive ...

Re: triac atc

I'm sure somebody more familiar with all the variations will comment, but I'm pretty sure Denford only ever used induction motors (very early machines), or Permanent Magnet DC motors (typically SEM).
The latter, two wires are for power, and two for the tacho output, along with the GND wire.
