TheHybrid servo drive itself has warning messages and protection functions such as over-voltage,
low-voltage, over-current, etc. Once a fault occurs, the protection function is activated, theHybrid servo
drive stops output, and the motor comes to stop freely. Please look up the cause for the fault and perform
the countermeasure according to the error message of theHybrid servo drive. The error records are stored
in the internal memory of theHybrid servo drive (last six error messages can be recorded) and can be read
out through the digital keypad or through the communication port.
TheHybrid servo drive consists of a large number of parts including ICs, resistors, capacitors, transistors,
other electronic components, cooling fans, and relays, etc.
These parts are not permanent and will
eventually need replacing. Even in a normal environment, the components are prone to failure after the
lifespan is reached. Therefore, preventive and regular inspection should be carried out so as to find out the
part that does not meet the specifications or has poor quality so as to exclude the causes that may cause
the failure of theHybrid servo drives. In addition, the inspection also helps the user to replace various parts
that have reached their lifespan in order to ensure normal and safe operation.
It is necessary to visually inspect the operation of theHybrid servo drives routinely to make sure that no
abnormal condition occurs. Meanwhile, check if the following conditions occur:
; After a fault occurs, the RESET button will be effective only 5 seconds after the fault
condition is released.
; ForHybrid servo drives of power rating 22kW, it is necessary to wait for 5 minutes ≦
(10 minutes for 30kW) after the power is shut down to confirm that the indicator ≧
light is off and the measured DC voltage across the terminals
and is below
DC 25V before opening the cover for inspection.
; Non-authorized personnel are not allowed to perform the maintenance work and
component replacement operation, (Before operation, it is necessary to remove the
metal objects such as watches and rings. Use insulated tools during the operation.）
; It is absolutely forbidden to modify theHybrid servo drive.
; Make sure that the operational performance and surrounding environment meet the
standards and there is no abnormal noise, vibration and odor.
