SERVOSTAR ® CD series servo amplifier

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.
