What Is Ovc Alarm In Fanuc Robot

Fellow Robot Wranglers I are functioning with a Fanuc Ur30a R-2000ib. The robot is definitely utilized in throwing to put melted aluminium intó molds (a die spreading robot) The robot eoat is usually a ceramic Iadle with a 7tl axis engine. The 7th axis revolves one path to fill the ladle in furnace and revolves opposite path to put the lightweight aluminum in mildew. This 7th axis obtain alot of OVC alerts. The alerts utilized to take place whenever the róbot ran a particular dumping program. I found the 7tl axis had been revolving to stop and caused it to mistake and OVC. As soon as i sped thé trajéctories up this fixed that ovc issue.

THE ISSUE I Have got NOW: If the robot is definitely informed to quit as soon as after it has filled up the ladle-(from bad machine indication) The 7tl axis totally relaxes and after that causes OVC alerts! How perform i obtain free of the OVC sensors on a ladle full of aluminum? Also shifting the robot in guide, if ladle is definitely full and the deceased man is certainly launched an OVC will occur. Some how 2nm shift often discovers a way to failing the robot and trigger OVC when it is no place near a accident. Yes Im certain it offers always operate at these settings trigger the fella who fixed it up 6 decades back hasn't been back again since, the ovc alarm started occurring after adding a software that calls for weightier fill to the 7tl axis. Increasing the gear ratio is performed on controlled start? I was going to consider to raise the permitted amp to fór that axis tó notice if that would impact the more than currents.but that axis disturbance torque cannot become adjusted, J7 it is certainly (.) with the alarm message Impact Detect Disabled.

Would Environment payload actually affect the turn of this axis? M7 it can be in SubGroup 1 and not a separate group 2. When has been the last time the 7th axis fat/oil transformed? Since it's subject to heat, it could be now be a stinky, black, watery product that offers little worth as a lube. Verify for steel content in the fat/oil, you may have a keeping going bad. Engine could also be the mistake if it weak or offers a pulling brake.

Actually the servo amp could result in this. Not certain what you indicate by 'relaxes' but it seems like a bad brake pedal.

Upping the fill and extending out the accel period as Racermike stated would become where I would start if all mechanised/electrical is certainly good.

What is definitely a FANUC 414 Servo Alarm? A FANUC 414 servo alarm is created by thé CNC whén it picks up that an amplifier provides a high current alarm 8, 9, or A. To figure out the specific cause, you must go through the procedure of removal. The higher current alarm may become caused by the servo drives, amplifiers, segments, motor and/or wires. In some situations, this alarm may show a brief to ground. The short is leading to too very much present to flow through the strength module inside the ampIifier and will ultimately cause it to split. Here can be the FANUC 414 Servo Security alarm message: Alarm Code Message Explanation 414 SERVO Security alarm: n-TH AXIS - DETECTION RELATED ERROR N-th axis (axis 1-8) digital servo program problem.

Refer to diagnosis screen Zero. 204 for details. Appear at the sérvo amplifier for aIarm code. How to Diagnose a FANUC 414 Servo Security alarm: Phase 1 - Access the electronics cupboard with the power on (WARNING: Hazardous voltage inside).

Action 2 - Appear for the amplifier unit showing either FANUC sérvo alarm 8, 9, or A on the seven portion display. Phase 3 - Alarm 8, 9, and A are all the same problem.

Nevertheless, the different alarms recognize which amplifier áxis the alarm is present on. Program code Message Description Security alarm 8 Irregular current alarm (D axis) Situated below the reasoning board, Alarm 8 shows an unusual current in the very first axis on thé amplifier which will be labeled (D). Security alarm 9 Unusual present alarm (M axis) Located below the reasoning board, Alarm 9 indicates an abnormal current in the 2nd axis on thé amplifier which is certainly labeled (Meters). Alarm A Unusual current alarm (N axis) Located below the logic board, Security alarm A signifies an unusual current in the 3rd axis on thé amplifier which is certainly tagged (A).

If your amplifier just handles two axes, yóur CNC should never ever screen an Alarm Code A. Phase 4 - Change on the major breaker of the machine and leave the CNC away. If FANUC sérvo alarm 8, 9, or A shows up when the CNC can be off, disconnect the suggestions connector to the amplifier axis pointed out by the alarm and turn on the primary breaker with the CNC away again. If no alarm appears, there will be an concern with the feed-back wire or the heart beat programmer. If alarm 8, 9, or A seems with the responses cable disconnected, the amplifier is definitely most most likely faulty and needs to end up being replaced. If the alarm ONLY shows up when the CNC is definitely turned on, you need to troubleshoot the commute, engine, and strength cable.

Action 5 - Disconnect the four engine potential clients from the bottom level of the amplifier. Action 6 - Convert on the CNC and discharge any crisis stop condition (if you're also eliminating the engine energy with a vertical axis, actually prop up the áxis or eIse it will drop when the emergency end and servo motor brakes are usually launched). Stage 7 - If an alarm 8, 9, or A nevertheless seems, the get is possibly faulty and requires to end up being replaced. Step 8 - If an alarm doesn't show up, the engine and/or power wire may be defective and desires to be diagnosed. Action 9 - With an ohm meter, verify for shorts in the engine by measuring leg-to-Ieg and leg-tó-ground on aIl three legs.

What Is Ovc Alarm In Fanuc Robotics

An ohmmeter will inform you if your engine will be shorted. Leg-to-leg readings should become reduced, but consistent, on all three hip and legs. The leg-to-ground readings should be open (OL) on aIl three legs-tó-ground.

Phase 10 - With a megger, check out each leg-tó-ground. A mégger will tell you if your engine can be grounded. The reading should show infinity (or 500 MEG and above) at the 1000V setting. Check all three Iegs-to-ground bécause the issue can be in the strength plug/terminal box of the electric motor or the energy cables heading from the get to the electric motor.
