• The value of this parameter should not be less than
the value of tb (delay of braking) in order to avoid
the minute movement or fall of the motor (work).
• Pr6A = (Entry) x 2 ms
• See also "Timing chart for Servo-ON/OFF during
the halt of motor" in Appendix 12.

• This parameter is necessary for avoiding the
degradation of the brake due to the rotation of the
motor.
• The value of T
the time needed for decreasing the motor
speed to about 30 r/min , whichever is smaller.
• Pr6B = (Entry) x 2 ms
• See also "Timing chart for Servo-ON/OFF during
the halt of motor" in Appendix 13.
