| Yellow - 4 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Command Speed Too High Probable cause: commanded speed/velocity is beyond motor spec. |
| Yellow - 4 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Tracking Error Limit Exceeded Possible causes: excessive friction, mechanical misalignment, vel/accel too high, low DC bus voltage. |
| Yellow - 4 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | RMS Torque Limit Exceeded Possible causes: excessive friction, mechanical misalignment, duty cycle too high, undersized motor. |
| Yellow - 4 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Excessive Bus Current Probable cause: bad tuning, low bus voltage. |
| Yellow - 5 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Excessive Motor Temp Possible causes: ambient temperature too high for motor load; poor cooling; fan not running (if used). |
| Yellow – 6 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Momentary Low Bus Voltage Power supply drooped below 18V, insufficient current capabilities, and/impedance too high. |
| Yellow - 7 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Old Config File Version Probable cause: Firmware updated after config file was saved. Create or load new config file. |
| Yellow - 7 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Motor Phase Overload Phase current is beyond allowed ADC limit. Probable cause: incorrect tuning or wrong config file. |
| Yellow - 7 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Hard Stop Gave Way A mechanical hard stop was detected during homing but it gave way before homing was completed. |
| Yellow - 7 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Excessive Bus Current Probable cause: bad tuning, low bus voltage. |
| Yellow - 7 blinks | Shutdown | Disallows motion | Servo off | Toggle Enable input | Commutation Startup Error DC bus too low for proper commutation start-up. Possible causes: brown out, incorrect power supply voltage, supply configured for higher AC line voltage. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | Velocity Set Too High Velocity/speed limit exceeds motor's factory-set maximum speed. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | RAS Change Rejected Unexpected error. Contact Teknic for work-around or new firmware. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | Step Input Timing Error Possible causes: Step input pulse width too short, electrical noise, loose connection, shorted wires. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | Speed Too High For RAS Unexpected error. Contact Teknic for work-around or new firmware. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | MagAlign Distance Error Distance traveled does not match expected value. Possible cause: motor against an end stop, incorrect motor settings. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | MagAlign Direction Error Direction traveled is incorrect. Probable cause: external forces during MagAlign procedure. |
| Yellow - strobe | Shutdown | Disallows motion | Servo off | Toggle Enable input | DSP Watchdog Restart Firmware problem. Re-flash firmware with same or newer firmware version. Return unit to Teknic if problem not solved. |
| Green/Yellow alternating | Lockdown | Disallows motion | Servo on | Toggle Enable input | Travel Limits Violated (lockdown) Commanded position is on the wrong side of the home position. |
| Green/Yellow alternating | Lockdown | Disallows motion | Servo on | Toggle Enable input | Travel Limits Violated (lockdown) Commanded position is beyond the Max Travel from Home position as specified in Homing Setup. |
| Green/Yellow alternating | Lockdown | Disallows motion | Servo on | Toggle Enable input | Motor Enable Conflict The hardware inputs did not match the active software override inputs when the motor was enabled via the hardware enable line. |
| Green – 2 blinks | Warning | Allows motion (if cause is no longer present) | Servo on | Auto-clears at start of next move if cause is no longer present | Travel Limits Violated (warning) Commanded position is on the wrong side of the home position. |
| Green – 2 blinks | Warning | Allows motion (if cause is no longer present) | Servo on | Auto-clears at start of next move if cause is no longer present | Travel Limits Violated (warning) Commanded position is beyond the Max Travel from Home position as specified in Homing Setup. |
| Green – 2 blinks | Warning | Allows motion (if cause is no longer present) | Servo on | Auto-clears at start of next move if cause is no longer present | Move Buffer Underrun Possible causes: move increments too small or sent too slowly. |
| Green - 3 blinks | Alert | Allows motion | Servo on | Auto-clears when cause is no longer present | Torque Saturation Power supply may be insufficient for application, torque Limit may be set too low for command. Try lowering acceleration. |
| Green - 3 blinks | Alert | Allows motion | Servo on | Auto-clears when cause is no longer present | Voltage Saturation Available bus voltage maxed out. Commanded speed may exceed motor spec. Try lowering speed. |
| Green - 3 blinks | Alert | Allows motion | Servo on | Auto-clears when cause is no longer present | Over Speed Commanded speed exceeds motor max speed limit. Try lowering speed. |
| Green - 3 blinks | Alert | Allows motion | Servo on | Auto-clears when cause is no longer present | Over Temp Internal electronics above shutdown threshold. Add fan. |
