Pulse output No.:

**:
Invalid area
Total No. of output pulses:
H0000 to HFFFF (0 to 65535)
Maximum frequency (Hz):
HA to H1388 (10 to 5000)
Initial frequency (Hz):
HA to H1388 (10 to 5000)
Acceleration/deceleration time (ms):
H0000 to HFFFF (0 to 65535)
This instruction outputs pulses with the acceleration/deceleration function.
It outputs pulses from the pulse output terminal set with the pulse output number s until the total number of output pulses set
with s+1 is reached.
Since the output of pulses starts from the one having the frequency set with s+3, set the parameters so that the stepping motor
and other devices will not become out of tune.
Acceleration is performed at the acceleration time set with s+4 in 10 steps until the maximum frequency set with s+2 is reached.
Deceleration is performed at the deceleration time set with s+4 until the total number of output pulses set with s+1 is reached.
The ratio of frequency change for the deceleration is the same as for the acceleration.
