Fatal malfunction (requiring power outage/enable reset):
Overheating (t): Check if the cooling fan and load are overloaded, reset after cooling;
Overvoltage (o): Reduce deceleration rate and check the connection of the regeneration resistor;
Overcurrent (P): Check for motor short circuit and power level fault, and power off reset is required;
Feedback fault (r0-r13): Check for broken feedback cables (such as r1=rotary transformer broken, r4=encoder A/B broken), reconnect and reset.
Non fatal malfunction (enable reset):
Undervoltage (u): Check the input voltage and eliminate power supply faults;
Motor overheating (H): Cool the motor and check the thermostat wiring (C2 Pin13/25);
Overspeed (J/J1): Adjust VOSPD (overspeed threshold) or VLIM (speed limit) to optimize the tuning parameters of the speed loop.
No message fault (only displayed in the status bar):
Limit trigger (L1/L2/L3): Hardware limit switch open circuit (C3 IN1/IN2), check mechanical limit or wiring;
Memory failure (I/c): RAM/EPROM test failed, hardware replacement is required;
Watchdog (≡): Software malfunction, contact manufacturer technical support.
