    Citizen L432 Servo alarm

    I have a Citizen L432 from 1998 with a Mitsubishi meldas 500 control
    In the last couple of days the machine has alarmed out with the following
    S04 SERVO ALARM : AR 006C S1
    EMG EMERGENCY SRV
    It happens at intermittent times and at different points in my part program.Does anyone have any suggestions or knowledge of this error code?

    6C Main circuit error

    The main circuit capacitor in the power supply could not be charged correctly

    Replace unit

    I have the same alarm with a L520.
    Did you change the power supply and solved the problem ?
