Cause
Don't using the regenerative brake
option.
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
Power supply voltage high.
The SSCNET cable is
disconnected.
The SSCNE cable fault.
Noise has entered the SSCNE
cable.
The terminal connector is
disconnected.
The same No. exists in the interface
unit 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.
Interface unit fault caused the IFU
parameter setting to be rewritten.
value was set to outside the setting
range by QD75M.
