AS64 series AC servo drive Operating and running
-65-
⚫ The servo enabling terminal SON is set to OFF. This does not cause regenerative brake.
You can select a stop manner through P4.30.
⚫ A fault alarm is reported. This does not cause regenerative brake.
You can select a servo motor stop manner through P4.30.
⚫ When the digital input terminal configured as zero speed clamp (ZRS) is set to ON and P0.58 is
set to a non-zero value, the servo motor stops running. When P0.58 is set to 1–3, the motor stops
running based on the DEC time set by P0.55 and P0.57 in speed mode, and servo is in locked
state after stop; in torque mode, the servo motor stops running immediately. Such stopping
process may cause regenerative braking. If a braking overload fault alarm occurred, connect a
proper external brake resistor.
⚫ If the travel limit switch function is invalid (that is, P3.40=0), and the digital input terminal signal of
travel limit (POT/NOT) is set to ON, the motor decelerates to stop running based on the settings
of P0.55 and P0.57 and it enters locked state. If there is reverse direction command input after
the motor stops, the motor can run in reverse direction.
⚫ If the emergency stop disabling function is invalid (that is, parameter P3.41=0), and the digital
input terminal of EMG is set to ON, the servo motor coasts to stop.
⚫ If the servo disabling signal duration is too short (that is, less than 500ms), the PWM signal may
be in off state after the servo is enabled again.
