When the absolute pulse coder is used, the motor has not yet rotated through more than one turn after the first power-up. The input power supply is abnormal open phase or the main circuit capacitor was not recharged within the specified time. Regenerative discharge energy is too high. 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.

OH occurs when a normally closed thermostat contact which is mounted either in the servo amplifier, on a separate discharge unit, or in a power transformer has opened. DC occurs when the capacity of the the discharge circuit has been exceeded. LV occurs when the DC link voltage is excessively low or the regulator circuit has a malfunction. HC occurs when excessive current has crossed the DC link.

DRDT indicates the ready state f servo servo amplifier. Please contact us if you need testing, a repair or an exchange part. The LED indicators on the printed circuit boards of a servo amplifier indicate states of the servo amplifier. Fgf fatina alzata in tessuto rosa cm 27x87 fgf08740.
