Operands:
S
1
: Maximum speed of pulse output
S
2
: Total number of output pulses
S
3
: Acceleration/deceleration time (ms)
D
: Pulse output device (please use transistor output module)
Explanations:
1. See the specifications of each model for their range of use.
2. For ES/EX/SS series MPU, PLSR instruction can be used twice in the program but the outputs cannot be
overlapped.
3. Flags: See remarks of API 57 PLSY.
4. Range of
S
1
: 10 ~ 32,767Hz (16-bit); 10 ~ 200,000Hz (32-bit). The maximum speed has to be 10’s multiple; if
not, the 1s digit will be left out. 1/10 of the maximum speed is the variation of one acceleration or deleration.
Please be aware if the variation reponds to the acceleration/deceleration demand from the step motor, in case
the step motor may crash.
5. Range of
S
2
: 110 ~ 32,767 (16-bit); 110 ~ 2,147,483,647 (32-bit). If
S
2
is less than 110, the pulet output will be
abnormal.
6. Range of
S
3
: below 5,000ms. The acceleration time and deceleration time have to be the same.
a) The acceleration/deceleration time has to be 10 times longer than the maximum scan time (D1012). If not,
the slope of accleration and deceleration will be incorrect.
b) The minimum set value of acceleration/deceleration time can be obtained from the following equation:
90,000
>

S
1
If the set value is less than the result obtained from the equation, the acceleration/deceleration time will be
longer. If the set value is less than 90,000/
S
1
, use the result of 90,000/
S
1
as the set value.
c) The maximum set value of acceleration/deceleration time can be obtained from the following equation:

d) The speed variation is fixed to 10 steps. If the input acceleration/deceleration time is longer than the
maximum set value, the acceleration/deceleration time will follow the maximum set time. If shorter than the
minimum set value, the accleration/deceleration time will follow the minimum set time.
