**RESOLVED** dc310b error 4 limit tripped

Post by rppman »

So I powered up for the first time and I followed the instructions list in the "what's first" topic and I got a "4" which means "limit tripped" on the lcd on the dc410b. In mach 3 the first message I got was "x axis error" but then it just read "emergancy error". I had one block in the middle right of the screen flashing red. I tried switching my limit dip switches for the limit switch functions and I would try to reset with no luck.

If you have a 4 on the 7 segment display of the DC3IOB your limit defeaters are down (angled down towards the PCB board) and either you don't have any limit switches wired to the PLC, the switches are wired for NO when they need to be NC or a limit is tripped.

Limit switches must be wired for normally closed to create a closed loop. So if the limit switch is made or the cabling to the switch breaks you get a limit tripped message.

If the limit defeaters are in the up position (parallel to the PCB board) your limit are defeated and you will not see a number 4 on the 7 segment display.
When requesting support, please ALWAYS post a current report. Find out how to take a report from your Acorn, CNC11 or CNC10 system here: https://www.youtube.com/watch?v=Ecvg0VJp1oQ.

If your question is PLC, Macro or program related, please also post a copy of the program or macro as well.

Without the above information we may not be able to help and/or reply until the required information is posted..

I do have the dip switches set to defeat the limit switches as directed on the "defeat limit switches" topic and it still shows an error 4. I had mach3 installed prior to starting my system for the first time. i had brains installed for a MPG which is not up and going yet. So, after reading the instructions on first time starting the system it said to not install any brains if you are not using them. I then went in and uninstalled mach 3 and the ajax plugin and started over. If the brains didnt get uninstalled would they be causing the problem. I will double check my switches again but i am almost positive i have them defeated out as you guys explained. Thanks for any input. Scott

I checked the switches and made some changes ans now the display on the dc310b reads "1". I don't have any documentation that tells me what that means? My mach 3 screen is still showing "emergancy" and the error message along the bottom says "z axis error". I also have my encoders hooked up and they are updating on all axis when I manually turn the shafts. Anyone know what display "1" means on the dc310b? Thanks scott.

i found this information on here about codes on the dc310b.
DC3IOB 7 Segment Display: Status and Error Codes
by ajaxscott » Mon Mar 22, 2010 2:40 pm

The DC3IOB features a red, 7 segment LED display which displays the operating status of the DC3IOB system

A steadily lit display of a number indicates a normal operating condition. A flashing number indicates a fault.

Normal Operating Condition
On a 3 axis system, a solid "1" or "0" is used to indicate the axis number of the first physical axis mapped on the DC3IOB. Earlier units were "zero indexed" which means simply that the first axis was mapped as zero, the second axis was mapped as axis 1 and so on... All current versions are "one indexed", which means that the that the first axis is mapped as axis 1, the second axis as axis 2 and so on... NOTE: "zero indexed" and a "one indexed" drives operate identically -Only the status display number denoting the first axis on the DC3IOB is different.

4 Axes+ DC3IOB Systems:
On DC3IOB systems with more than 3 axes, the display may display a solid 1, 2, 3 or 4 depending on the number of additional axes installed and their configuration. If a single axis DC1 servo amplifier is installed together with a "one indexed" DC3IOB, the DC1 will be mapped as the first axis and the DC3IOB will display a steady "2". If two DC1 servo amplifiers are installed together with a "one indexed" DC3IOB, the first and second axes will be mapped to the the DC1's and the DC3IOB will display a "3" indicating that the first available axis on the DC3IOB has been mapped as axis 3 (the 2nd and 3rd axes on the DC3IOB will be mapped as axis 4 and axis 5 respectively).

Fault Condition
Flashing "1"
Meaning: Power Failure
Cause: Logic power supply indicating it is operating out of specification
Corrective Action(s):
1. Check power supply wiring, (the grey wire and AC input in particular)
2. An I/O device may be miswired or drawing too much current.
Unplug all I/O headers to see if fault clears. If it does, reconnect I/O
one at a time to isolate the faulty device/wiring.
3. Replace power supply.

Flashing "2"
Meaning: 15A Not Available
Cause Current selection jumpers on any axis are set to 15A, but the drive is not equipped with the appropriate FETs for long term use at 15A.
Corrective Action(s)
1. Select 12A or lower current settings
2. Use a high power DC3IOB

Flashing "3"
Meaning Null Error
Cause The self adjust routine has detected too large an offset on the current feedback.
Corrective Action(s)
1. Send the drive back for repair.

Flashing "4"
Meaning Limit Tripped
Cause Any limit switch is tripped
Corrective Action(s)
1. Confirm switch is wired as normally closed.
2. Move away from the limit
3. Check limit switch wiring.
4. Defeat switch if limit switch is not required
See here for instructions describing how to defeat a limit switch: viewtopic.php?f=20&t=17
So i have a solid "1" but not really sure why I am still getting an emergany error in mach 3 screen "z axis error" or sometimes it says "x axis error"

I have started a new topic "x axis error". Being this origionaly started out as being a "limit tripped" topic and that problem is solved. On to the next!!
