• 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
tb
Defines the conditions for decelerating the motor and keeping
the motor stopped after one of the driver's protective functions
(alarms) is activated.
(DB : Dynamic brake engaged)
See also "Timing chart for alarms" in Appendix.
Defines the following processes after Servo-OFF (SER-ON signal: CN I/F
Pin 29).
1) Operating conditions during deceleration and after stop
2) Process for clearing the position error counter
The functions of this parameter and the meanings of parameter values
are the same as those of Pr67.
See also "Timing chart for Servo-ON/OFF during the halt of motor" in Ap-
pendix.
Defines the duration from OFF of the brake release signal (BRK-
OFF) (i.e. brake engaged) to the shutdown of motor current (servo
free) in transition to Servo-OFF during the halt of the motor.
See also "Timing chart for Servo-ON/OFF during the halt of
motor" in Appendix.
