![]() When the absolute pulse coder is used, the motor has not yet rotated through more than one turn after the first power–up. Reference position setting cannot be executed correctly. The regenerative discharge unit is heated. The offset of the current detection circuit of the main circuit DC link is excessive. Relay contacts for the dynamic brake is faulty. The input power supply is abnormal (open phase) or the main circuit capacitor was not recharged within the specified time.Ī communication error for the serial pulse coder was detected. Servo motor has overheated (estimated value).Īverage regenerative discharge energy is too high (too frequent acceleration/deceleration) –The regenerative discharge circuit is abnormal. Regenerative discharge energy is too high. The temperature of the heat sink has risen. +5 VDC of the control circuit power supply is abnormally low.ĭC voltage of the main circuit power supply is abnormally low or the circuit breaker is tripped. The battery voltage of the absolute pulse coder is low. ![]() Inverter: control power supply undervoltage Internal cooling circuit failure, Overload, Input supply voltage imbalance, IPM failure, or control supply voltage decrease of the power module. The main circuit power module (IPM) has detected an overload, overcurrent, or control supply voltage decrease, overcurrent, or control supply voltage decrease. Input supply voltage imbalance, IGBT defective. Overcurrent flowed into the input of the main circuit. If blinking continues → Replace the cable.Īmplifier is ready (normal operating state)ĭC voltage of the main circuit power supply is abnormally high. The cable on the Servo Amplifier side connected.) (b) Disconnect the feedback cable (JF*) from the Pulsecoder, and then switch on the power. If blinking continues → Replace the Servo Amplifier. ![]() (a) Disconnect the feedback cable (JF*) from the Servo Amplifier, and then switch on the power. ![]() 400 Alarms 600 Alarms Beta is 6130 Alarms SVPMi (6134, 6230) Alarms Alarm Code
