DVP-ES2/EX2/EC5/SS2/SA2/SX2/SE&TP Operation Manual - Programming
#
: Due to the lack of high-speed input for configuring the Z-phase function, the output of axes Y4 and Y6 does
not support this function.
4. When D is specified as Y0, its direction signal output is Y1; when D is specified as Y2, its direction
signal output is Y3. When D is specified as Y4, its direction signal output is Y5. When D is
specified as Y6, its direction signal output is Y7.
5. When pulse output reaches zero point, pulse output execution completed flag M1029 (CH0),
M1102 (CH1), M1321 (CH2), or M1322 (CH3) is ON and the register indicating current position is
reset to 0.
6. When DZRN instruction executes, if using CH0 (Y0, Y1), CH1 (Y2, Y3), the external interrupt
I400/I401(X4)) or I600/I601(X6) in program will be disabled until DZRN instruction is completed.
If left limit switch (X5 / X7) is enabled during instruction execution, external interrupt I500501(X5)
or I700/I701(X7) will be disabled as well.
7. When the DZRN instruction is executed and channels CH2 (Y4, Y5) and CH3 (Y6, Y7) are used,
the scanning instruction method is employed to detect the zero position, negative limit position,
and to stop the motion. Therefore, the execution process will be affected by the filtering time of the
input points and the PLC scan time. It is recommended that the pulse width time of the near point
(DOG) signal (which becomes shorter as the speed increases) should be greater than the input
filtering time.
8. Zero point position: the default position of zero point is on the left of DOG switch (the input point
On→Off) (as mode 1 shows below). If the user needs to change the zero point to the right of DOG
switch, set ON M1106 (CH0), M1107(CH1), M1588 (CH2) or M1589 (CH3) before DZRN
instruction executes.
9. Start the pulse-clearing function of the output. When DOG leaves DOG switch and is going to stop,
it will output another pulse (the width of On is about 20ms). When the pulse is On→Off, there will
be a completed flag output. Please refer to state 4 for the timing diagram of this function.
10. When D1312 is not set to be 0, and M1308=Off, the function of seeking Z phase is started. When
D1312 is a positive value (the maximum value is 10), it indicates that the search for Z-phase signal
is toward the positive direction. When D1312 is a negative value (the minimum value is -10), it
indicates that the search for Z-phase signal is toward the negative direction. For example, if
D1312 is k-2, it means that DOG stops immediately after DOG leaves DOG switch and searches
in the negative direction for second Z-phase signal (the fixed right-edge trigger) with JOG
frequency. Please refer to state 5 for the timing diagram of this function.
Note: The output of axes Y4 and Y6 does not support this function.
11. When D1312 is not set to be 0 and M1308=On, the function of outputting the designated number
of pulses is started. When Dd1312 is a positive value (the maximum value is 30000), it indicates
