MELSEC-Q
Cause
Lead of built-in regenerative brake
resistor or regenerative brake option
is open or disconnected.
Though the regenerative brake
option is used, the DRU parameter
" Pr.102 Regenerative brake
resistor "setting value is "0 00 (not
used)".
Regenerative brake option is open
or disconnected.
Regenerative transistor faulty.
Wire breakage of built-in
regenerative brake resistor or
regenerative brake option
Capacity of built-in regenerative
brake resistor or regenerative brake
option is insufficient.
Power supply voltage high.
The SSCNET cable is
disconnected.
SSCNET cable fault.
Noise has entered the SSCNET
cable.
The terminal connector is
disconnected.
The same No. exists in the servo
amplifier side axis setting.
Command given is greater than the
maximum speed of the servomotor.
Noise has entered the SSCNET
cable.
Fault in the QD75M.
The SSCNET cable is
disconnected.
The SSCNET cable fault.
Printed circuit board fault.
The terminal connector is
disconnected.
Servo amplifier fault caused the
parameter setting to be rewritten.
Parameter data mis-setting by
QD75M.
Servo motor ambient temperature
exceeded the operating value of
40°C.
Servomotor overloaded.
Thermal protector in encoder is
faulty.
