Spikemark Faults
Spikemark uses status icons to indicate your automation system's state. Use this guide to run your automation fault-free.
Working Conditions
Connected
You have no faults and are properly connected to your Stagehand Controller.
Cue Loaded
The cue is loaded. Pressing GO will run the loaded cue.
Moving Forward
Moving Forward in Target Tolerance Mode
Moving Forward in Strict Timing Mode
Jogging Forward
Moving Reverse
Moving Reverse in Target Tolerance Mode
Moving Reverse in Strict Timing Mode
Jogging Reverse
Cue Complete
Cue execution completed.
Soft Stop
Motion has Soft Stopped
Motion is in the process of soft stopping.
Faulted Condition
Disconnected
You are not connected to your Stagehand on the Network. Troubleshooting steps:
Verify network cable condition
Replace network cables if necessary
Emergency Stop
Your Stagehand is in Emergency Stop. Check:
Is the Showstopper Base powered with a green ready light?
Is the Stagehand connected to the Showstopper Base?
Are all terminators plugged into Showstopper Devices?
Inactive
When your machine is inactive, you cannot jog or move the machine in a cue.
Firmware Update
Update your firmware to ensure Spikemark communicates correctly with your machines..
Position Fault
Refer to the Position Fault Guide for detailed troubleshooting.
Group Fault
A Group Fault occurs when any machine in a group faults. If one motor faults, all motors in that group will fault.
Limits
Forward Limit
Reverse Limit
Ultimate Limit
Limits prevent machine collisions. Troubleshooting steps:
Move in the opposite direction to clear the limit
For Ultimate Limit, override the limit and jog off
Verify signal cable connection
Test with an alternate signal cable
Confirm correct machine limit settings
Cross Groove
Cross Groove detection functions similarly to a limit switch. For hoists:
The sensor is typically a roller held with a spring to the drum
If the wire rope jumps a groove, run the machine in reverse to clear the sensor
Seat the wire rope properly
Adjust the Cross Groove sensor per machine documentation
Make sure your seignal cable is plugged in
Interlocks
Prevents motion in the forward direction.
Reverse Interlock
Prevents motion in the reverse direction.
All Stop Interlock
Prevents motion in both directions.
Interlocks inhibit motion when two machines interact (e.g., stage lift and trapdoor). You might see these faults if a safety bumper is pressed.
Most effects do not require interlocks. If you see these faults without using interlocking, ensure the interlock terminator is plugged into the Stagehand Controller.
Externl Fault
The external fault signal monitors thermal overload when running two motors on the same Stagehand. If one motor draws excessive current, it triggers the fault.
Most effects do not require external fault. If you see this fault without multiple motors, ensure the interlock terminator is plugged into the Stagehand Controller.
Load Cell Faults
Overweight
Underweight
Load Cell Mismatch
Troubleshooting steps:
Verify machine weight is within acceptable range
For machines without a load cell, accept Stagehand values and turn off load alarms
Brake Fault
The Variable Frequency Drive (VFD) monitors brake contactors. A fault occurs if the contactor output doesn't match the commanded state.
Potential non-fault scenarios:
Emergency stop engaged
VFD stuck in autotuning - Quit Spikemark, and [reset your VFD Parameter to the default Parameters](/stagehand/
Internal wiring issue
Sadly, if you truly have a Brake Fault, it means that one of the contactors is broken and needs to be sent back to Creative Conners for repair.
Drive Fault
When a drive fault occurs, check the Drive Pane in Spikemark for specific fault details.
Refer to the VFD Fault Codes for comprehensive troubleshooting.
You can also open up the Fault Histroy window to see more information regarding your fault
After you identify which fault you have, use the information below to help identify and fix your issue.
Here is full list of the VFD Fault Codes
Common Fault Codes
E.OC2
Overcurrent trip during constant speed
Check for sudden load change
Run a Brake Test and ensure both brake circuits are working
Check for a short-circuit in the output circuit
Verify rotation direction (Pr. 359) is set correctly
Confirm motor capacity (Pr. 80) is set correctly
E.OV2
Regenerative overvoltage trip during constant speed
Check motor cable
Likely overloaded brake resistor
Reduce Load
Reduce Speed
Reduce Travel Distance
Install a larger brake resistor
E.THM
Motor overload trip (electronic thermal relay function)
Reduce Load
E.OLT
Stall prevention
Reduce Load
E.OSD
Speed deviation excess detection
Check that the speed encoder is tight to the motor
Swap Motor Cable
Run a brake test - The Brake might not be releasing
Verify Pr. 285 and Pr. 369 are set correctly
E.ECT
Signal loss detection
Speed Encoder is disconnected
Plug in signal cable
Check 5VDC 1 Amp fuse on Stagehand
Ensure encoders are wired correctly and can receive 5VDC power input
Change Pr. 800 to 10 (Caution: Do not do this in lifting/hoisting applications)
E.EP
Encoder phase fault
Check that Speed Encoder is wired correctly
Less Common Fault Codes
E.OC1
Overcurrent trip during acceleration
Stagehand Pro does not use Drive Level Acceleration. This fault should never happen.
E.OC3
Overcurrent trip during deceleration or stop
Stagehand Pro does not use Drive Level Deceleration. This fault should never happen.
E.OV1
Regenerative overvoltage trip during acceleration
Stagehand Pro does not use Drive Level Acceleration. This fault should never happen.
E.OV3
Regenerative overvoltage trip during deceleration or stop
Stagehand Pro does not use Drive Level Deceleration. This fault should never happen.
E.THT
Inverter overload trip (electronic thermal relay function)
Temperature of output transistor elements exceeds protection level
Verify Pr. 0 and Pr. 14 are correct
Check Speed encoder meets specifications and is wired correctly
Reduce Load
E.FIN
Heat Sink Overheat
Check that the VFD fan is clean
The VFD needs repair
E.UVT
Undervoltage
Check Input Power
E.ILF
Input phase loss
Check Input Power
E.SOT
Loss of synchronism detection
Not used. If you see this error, your Stagehand Pro will need repair
E.BE
Brake transistor alarm detection
Remove Power
Replace VFD
E.OS
Overspeed occurrence
Check Pr. 374 and Pr. 369
