Brake Excitation
T (before detecting excitation) = SON signal identification (6ms) + Excitation detection time (T1
+ T2) × Number of retry (10 times Max.) + Servo ON delay
time (T3)
T (after detecting excitation) = SON signal identification (6ms) + Servo ON delay time (T3)
T1 : Parameter No.30 It differs depending on the setting of excitation detection type.
Set Value = 0 ĺ 160ms
Set Value = 1, 2 ĺ 220ms
T2 : Parameter No.29 Setting of excitation phase signal detection time
It is set to 10ms in the initial setting.
T3 : Fixed to 20ms
(Note) • Excitation check operation is performed at the first servo-on process after the power is
turned ON, or when the home return is completed for the simple absolute type to
identify the magnetic poles of the motor.
• PEND would not turn ON in the pause condition.
