MAC mini iH Series Maintenance ManualAlarmsErr. No.D00D01D02F10F20Description of alarmPOS-DEV OverC a u s e1. Servo pack substrate is broken.2. Connection among the motors U, Vand W is wrong.3. Motor gain adjustment error.4. Frequency of position command pulseis too high.5. Position deviation over level (PRM623)is not adequate.6. Load condition and motor specificationare not adequate.Servo OFF POS-DEV over1. Position deviations are accumulatedexcessively when servo is OFF.Servo ON POS-DEV over1. When servo is turned ON with positiondeviations increased, command pulseis inputted during operation at thelimited speed, exceeding the positiondeviation over alarm level (PRM623).Power line open-phase1. Servo pack is broken.2. Wiring for three-phase power sourceis wrong.3. Imbalance in the three-phase powersource.Motor cable disconnectionD e t a i l sC o u n t e r m e a s u r e sPosition deviation exceeds PRM623 when servo is ON.1. Replace the servo pack.2. Correct the motor wiring.3. Raise the set values of velocity loop gain(PRM510) and position loop gain (PRM512).4.1. Raise or reduce the frequency of positioncommand pulse.4.2. Review the electronic gear ratio.5. Optimize the position deviation over level (PRM623).6. Review the load.1. Keep the motor stop when servo is OFF.1-1. Keep the motor stop when servo is OFF.1-2. Optimize the limited velocity level (PRM628)when servo is ON.In either R, S or T phase remains at low voltage for 1second when the main power source is ON.1. Replace the servo pack.2. Correct the power source wiring.3. Repair the imbalance in the power source(Replacement among phases).Motor cable is disconnected.1. Motor cable is disconnected. 1. Review the motor wiring.CPU00400Main CPU communication error1. Communication cable connection error2. Main board is broken.3. Servo pack is broken.Machine zero position unset1. Machine zero position is not establishedyet.Communication between the controller main boardand servo pack is incorrect.1. Check the connection of communication cable.Replace the cable.2. Replace the controller.3. Replace the servo pack.Machine zero position is not set yet.1. Set machine zero position.(See the section; machine zero positioning)KITAGAWA I1-27
