t2<26μs(Note4)
t4<15μs[24μs](DEND is assumed to be turned on while DRST is being produced.)
Note1: Indicates that the FAST STOP command is written.
Note2: Either command or signal may be used.
Note3: The number of pulses to be output after receipt of the FAST STOP command is 1 pulse or less.
(The pulse width is secured.)
Note4: When T represents 1/2 of the pulse cycle as the drive is stopped, t2 takes the indicated value or
T which ever is longer.
12-10.LIMIT STOP Timing
(1) When the LIMIT stop type is slow stop:
Example) DRIVE in +(CW)direction when the target is a stepping motor

Note1: The number of pulses to be output after receipt of the LIMIT signal is
1 pulse or less at constant-speed DRIVE or the number of pulses
required for slow stop at accelerating/decelerating DRIVE.
(2) When the LIMIT stop type is fast stop:
Complies with 12-8. or 12-9. Timing.
At this time, the FSSTOP signal is replaced with CWLM or CCWLM and the input signal width is set to 400μs.
