Post 2020 machines signal error conditions with audible and/or visual codes which are explained in the table below.
Error conditions are signaled by blinking of the “information light” next to the power button of the machine and the firmware LED on the logic board. High priority codes will be accompanied by audible beeping of the same pattern.
Operation Modes
Two general operation modes can be differentiated:
- Normal operation is indicated by:
1/2 second on, followed by
1/2 second off, continuous blinking.
- Error condition is indicated by:
2 second off, followed by
1/4 second (0, short) or 1 second (1, long)
Fault Codes
The pulses in error condition indicate an eight-bit binary error-code with:
- short pulse = 0 which is 1/4 second long
- long pulse = 1 which is 1 second long
Low Priority Codes
Visual signal of the information light and firmware LED only
Code | Meaning |
|---|---|
An emergency stop button has been depressed. This is not strictly an error condition. | |
The pendant is missing or malfunctioning. | |
The machine is in standby mode. | |
The x-axis has encountered an encoder limit. | |
The y-axis has encountered an encoder limit. | |
The z-axis has encountered an encoder limit. | |
0000 1000 | Stall, x-axis. The motor could not move the stage. |
0000 1001 | Stall, y-axis. |
0000 1010 | Stall, z-axis. |
0000 1100 | Following error fault, x-axis. The following error for the motion control system has exceeded the fault threshold. |
0000 1101 | Following error fault, y-axis. |
0000 1110 | Following error fault, z-axis. |
0000 1111 | Synchronization error fault, x-axis. The linear and rotary encoder differ too much. |
0001 0000 | Synchronization error fault, y-axis. |
0001 0001 | Synchronization error fault, z-axis. |
0001 0011 | Overcurrent, x-axis. The amplifier board has reported that the axis current has exceeded its configured maximum. |
0001 0100 | Overcurrent, y-axis. |
0001 0101 | Overcurrent, z-axis. |
0001 0110 | Servo overtime fault. The regulator failed to be run in a timely manner. |
0001 1000 | Find volume fault. The find volume process for the x, y, and z-axis failed. |
0001 1001 | Find range fault. The find range process for the zoom motor failed. |
0001 1010 | Platen device fault. The platen has encountered an error and is in a faulted state. |
0001 1011 | Rotary device fault. The rotary has encountered an error and is in a faulted state. |
High Priority Codes
Visual signal of the information light and firmware LED in combination with accoustic signal of the pieze speaker.
High priority codes override low priority codes
Code | Meaning |
|---|---|
0010 0000 | Encoder failure, x-axis. |
0010 0001 | Encoder failure, y-axis. |
0010 0010 | Encoder failure, z-axis. |
0010 0100 | Encoder reversed, x-axis. |
0010 0101 | Encoder reversed, y-axis. |
0010 0110 | Encoder reversed, z-axis. |
0010 1100 | Runaway, x-axis. The stage moved unexpectedly. |
0010 1101 | Runaway, y-axis. |
0010 1110 | Runaway, z-axis. |
0011 0000 | Fan failure, enclosure. |
0011 0001 | Amplifier board configuration failure. |
0011 0010 | Define, Tuning, or Accessory file is successfully read but invalid. |
0011 0011 | A platen was detected, but communication to it was interrupted. |
