8. The ELC-PH, when the ZRN instruction is executed, the current value of the pulse output
frequency will be in (D1348, D1349) and (D1350, D1351). After the ZRN instruction is
complete, 0 will be in (D1348, D1349) and (D1350, D1351).
9. The ELC-PH, when the input conditions to the ZRN instruction are ON, the value in
D1343(D1353) will be used as aeceleration/deceleration time for Y10 (Y11). After accelerating
to zero point return speed, wait for the near point signal (DOG) and the output will decelerate
at the creep speed. Immediately stop the output pulses when the near point signal (DOG)
turns OFF.
10. In the ELC-PH, this instruction can be used many times in the program, but only one
instruction may be activate at a time.
11. In the ELC-PH, when Y10 is used as the output, X10 or X11 may be used as the near point
signal input of the conversion from acceleration to deceleration. When Y11 is used as the
output, X10 or X11 can also be used as near point signal input.
12. In the ELC-PH, because there is no output number comparison for this instruction, the
conversion condition (from OFF to ON) must come from the near point signal when using Y10.
Otherwise, the instruction can’t be converted from acceleration to deceleration. Also, the
trigger time should be more than 10us.
13. In the ELC-PH, the current accumulated pulse count of Y10 is stored in D1348 and D1349.
The current accumulated pulse count of Y11 is stored in D1350 and D1351. It will not be
cleared to 0 when the program transitions from STOP to RUN or from RUN to STOP.
14. In the ELC-PH, when M1102=ON, it indicates Y10 pulse output is complete. If M1103=ON, it
indicates that Y11 pulse output is complete..
15. When instruction is in deceleration and the output frequency reaches creep speed, the output
pulses will stop when the near point signal transitions from ON to OFF.
16. During instruction execution, parameters cannot be modified until instruction execution is
completed.
17. When the instruction is OFF, all outputs will stop.
Description: (ELCM-PH/PA)
1. S
1
(zero return speed): max. 100kHz. S
2
(JOG speed for DOG) must be less than S
1.
The JOG
speed for the DOG also refers to the start frequency.
2. S
3
and D operands must be used as an input/output set according to the table below, i.e. when
S
3
is specified as X4, D must be specified as Y0; also when S
3
is specified as X6, D must be
specified as Y2.
3. M1307 enables (ON) / disables (OFF) the left limit switch of CH0 (Y0, Y1) and CH1 (Y2, Y3).
M1307 must be set up before the instruction executes. M1305 and M1306 can reverse the
pulse output direction on Y1 and Y3 and must be set up before instruction executes.
