be treated as its regular set-point.
c) Maximum set-point of the accel/decel time can be obtained from the following equation.
818
d) The number of the accel/decel speed variation steps is fixed at 10 steps. If the input
acceleration/deceleration time is greater than the maximum set-point, the maximum
set-point will be treated as its regular set-point. If the set-point is smaller than the minimum
set-point, the minimum set-point will be treated as its regular set-point.

6. The acceleration is performed when the pulses go from the static state to reaching its targeted
speed. Then it slows down the closer it gets to its targeted distance. The pulse will stop its
output once the targeted distance is reached.
7. When the PLSR instruction has been executed, its output frequency is first increased in
increments of 1/10 of the maximum frequency
S
1
/10 and the time of each output frequency is
fixed at 1/9 of
S

.
8. The output will not be affected if

are changed when PLSR instruction is being
executed.
9. For ELC-PB/PC/PA/PH, ELCB-PB series, when all the Y0 pulses have been sent, M1029 will
be On; when all the Y1 pulses have been sent, M1030 will be On. Next time when PLSR
instruction is enabled, M1029 or M1030 will be reset.
10. For ELC-PV series, when all the CH0 (Y0, Y1) pulses have been sent, M1029 will be On; when
all the CH1 (Y2, Y3) pulses have been sent, M1030 will be On; when CH2 (Y4, Y5) pulses
have been sent, M1036 will be On; when CH3 (Y6, Y7) pulses have been sent, M1037 will be
On. Next time when the PLSR instruction is enabled, M1029, M1030, M1036 or M1037 will be
reset.
11. For ELC-PV series, if the set value falls out of the allowable range of operands it will be
automatically corrected with the min. or max available value.
12. ELC-PV series has four groups of A-B phase pulse outputs CH0 (Y0, Y1), CH1 (Y2, Y3), CH2
(Y4, Y5) and CH3 (Y6, Y7). See the remarks in API 57 PLSY for more information.
13. During the acceleration of each step, the pulse numbers (each frequency x time) may not all
be integer values, but the ELC controller only uses integer values for this operation. Therefore,
the time of each interval may have some deviation. The offset is determined by the frequency
value and by discarding the decimal point value. In order to ensure the output pulse values are
correct, the ELC will fill in pulses as needed to keep any deviation to a minimum.
14. For ELC-PB, ELCB-PB series, PLSR instruction can be used twice in the program but the
outputs cannot be repeated.
