Maintenance
Note 1) When the main power voltage increases or decreases gradually or is suspended,
main circuit low voltage or main power failed phase may be detected.
Note 2) Control power supply under-voltage or servo ready OFF is detected during
instantaneous break of 1.5 to 2 cycles. Detection of control power supply
under-voltage and servo ready OFF can be delayed by setting larger value of
Index 0x2027-0 "Power Failure Detection Delay Time [PFDDLY]".
Note 3) When moment cutting of a control power source is long, it regards in power
supply interception and re-input, and does not leave detected control power
supply under-voltage to an alarm history. (If cutting exceeds 1 second at the
moment, it will be certainly judged as power supply interception.)
Note 4) Due to abnormality in encoder main body, encoder clear may sometimes be
needed. "An encoder clear and the alarm reset method" change with motor
encoders in use. Please refer to "8.4 Encoder clear and the alarm reset
method".
Note 5) When there is a rapid motor slow down simultaneous with servo ON, there is a
possibility that a break in the motor’s power line cannot be detected.
Note 6) Alarm that occurs in ‘Test mode end’ status is not recorded in the alarm history.
Note 7) When encoder connector EN2 is used as motor encoder input, "Alarm reset" is
"No". When encoder connector EN2 is used as external encoder input, "Alarm
reset" is "Yes".
Note 8) For the servo amplifier with functional safety module, all alarms are treated as
diagnosis function, so Safe Torque Off function is performed simultaneously with
alarm occurring. That is reason why Safe Torque Off state continues after alarm
resetting. To start operation again, turn off the servo ON input and return to
servo ready state.
Note 9) For RS3D80#, alarm occurs when either of power unit and amplifier unit gets
into overheat state of unit internal module.
