I'm running two systems with the C86ACCP boards and Teknic ClearPath servos. One system has three servos (X, Y, and Z). The other system has two servos (X and Y). All axes are jumpered with Active...

I'm running two systems with the C86ACCP boards and Teknic ClearPath servos. One system has three servos (X, Y, and Z). The other system has two servos (X and Y). All axes are jumpered with Active...
Last Monday, I received a C86ACCP board for my Centroicnc Acorn Board and some Teknic ClearPath servos. Unfortunately, the board came without instructions. I visited their website and downloaded...
The schematic for the G540 shows that the inputs must sink current through an optocoupler that is in series with a 200 ohm resistor. The data sheet for the proximity sensor tells us that the...
Look at wiring diagram #1 at http://www.automationdirect.com/static/specs/proxrectaps4.pdf. That is all the information provided for the proximity sensor.
Buy one and experiment, then you'll know...
The APS4-12S-E-D is an NPN sensor that requires 10-30VDC input to operate correctly. You'll need to connect the Brown wire to the "+" voltage (10 to 30VDC). The Blue wire is connected to the G540's...
SteliosA,
I noticed your other post after I wrote about the Arduino. You'll have no trouble making a "black box interface" for your sensors. I've sent you some files. Those files are too large...
Buy an Arduino Uno (or similar) microcontroller and let the microcontroller provide a single output for multiple inputs. The Arduinos that I have on my test bench have at least 20 I/O lines...
It looks like the Sorotec units have the standard wire colors, i.e. Brown = +12VDC, Black = sensor output, Blue = Ground. Connect +12VDC to the Brown wire. Connect the Blue wire to Ground and then...
Mariss and Steve,
Thank you both very much. Even after using stepper motors in my process control equipment since 1982, and Geckodrives on my test bench since the G202 was first released, I've...
I'm a little confused about the figures. The G540 literature says that it is rated at 50VDC, 3.5A maximum per axis, which would be 14A total if everything was pulling absolute maximum current at the...
A DC power supply usually consists of three pieces, minimum:
1. Transformer
2. Bridge rectifier
3. Capacitor.
The transformer changes the amplitude of the voltage from the "line voltage"...
No, I haven't tried using proximity sensors in parallel. Because I don't have control of the entire circuit, I always build my process controllers to have only one input per signal.
If the input...
A proximity senses metal. It's up to you to decide how you're going to use it. Gerald at MechMate designed his machine so that the sensor detects a 'hole', i.e. a metal strip is in close enough...
It works fine.
I have an AM1-A0-2A sensor connected to my G540 right now. The brown wire is connected to terminal 1. The blue wire is connected to terminal 12. In Mach 3 I've assigned X++ to pin...
Have you verified the signal names and the polarity? For instance, when I use my G202 stepper drivers driven by a PMDX-122 break-out-board, the X-direction is Parallel Port Pin 2, but if I use the...
I've used many motors with the G540 that should have been used with a G203v or other 'high powered' Gecko drive. I limited the voltage to 48VDC. I limited the current to 3A (although I could have...
It's always hard to be caught in the middle when damage is done to electronics. For thirty years, I designed and installed process control computers for professional photolabs. It didn't take long...
Let's play Perry Mason for just a minute.
Given: Four drives were dead before sending them in for evaluation.
Given: At least two of the drives had had the cover removed by the end user.

The photos say it all. There is loose metal floating inside the cases. None of the ten G203v drives that I've purchased had any metal shavings. It looks like a clear case of misuse to me. I would...
The 268-01A motor has 14mH inductance when wired half-coil. That would require a 119VDC power supply to get full speed. The Geckodrive stepper drivers G201x or G203V are limited to 80VDC. The...
Thanks for that help. For several years, I've had an MCG-33004 motor connected to a Geckdrive G340 (modified to be a G320 by removing the pulse multiplier) servo driver sitting on the back of my...
One of my customers asked me to choose a 34-size servo motor from Keling for his application. I visited the Keling web site and downloaded the three data sheets - and then the confusion started.
...
Old motors can be a problem. Look around the various stepper motor manufacturer sites and try to find other motors that have similar specifications. For example a modern square type 23 frame size...
Let's assume that L2 is single-phase Neural and that L1 is AC Line. When the Relay is turned on, power will be available to the outlet on the Gantry.
The power input to the 5VDC power supply is...
According to the schematic found on the Gecko forum (yahoo groups), the inputs to the G540 are connected to an ILQ74 opto-isolator to 12VDC through a 2.2k resistor. The load on any device connected...
IF the relay uses 5VDC for activation, THEN if you connect terminal 4 to DC ground, the relay will be turned on whenever the 5VDC power supply is turned on. On the other hand, if you want to control...
Here is a quote from page 1 of the G201 manual found at www.geckodrive.com:
"Motor winding inductance should be 500uH or greater, but generally no more than 5.5mH."
Congratulations on getting things sorted out.
The sparking that you're getting when you plug in your power supply is due to in-rush current. Twenty to eighty times the normal current is...
The formula is 47 X Amps / (7 - Amps) = Resistor (K), so for the 5A rating, 47 X 5A / (7 - 5A) = 117K. If you use the 6A rating instead, 47 X 6A / (7 - 6A) = 282K.
A 1/4 watt resistor is fine. I...
Why not pre-install a current set resistor at the factory for those customers who specify the current rating of the stepper motor that they are going to use?
