DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming
3-364
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.
5. When pulse output reaches zero point, pulse output execution completed flag M1029 (CH0),
M1102 (CH1) is ON and the register indicating current position is reset to 0.
6. When DZRN instruction executes, external interrupt I400/I401(X4)) or I600/I601(X6) in program
will be disabled until DZRN instruction is completed. Also. 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. Zero point selection: the default position of zero point is on the left of DOG switch (the input point
On→Off) (as mode 1 shows). If the user needs to change the zero point to the right of DOG switch,
set ON M1106(CH0) or M1107(CH1) before DZRN instruction executes. (The function supports
ES2/EX2 series, V1.20 or above.)
8. 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. (The
function supports ES2/EX2 series, V1.20 or above.)
9. 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. (The function supports ES2/EX2
series of V1.20 or above, and SS2/SX2 series of V1.20 or above.)
10. 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
that the pulses are output in the positive direction. When D1312 is a negative value (the minimum
value is -30000), it indicates that the pulses are output in the negative direction. For example, if
D1312 is k-100, it means that DOG stops immediately after DOG leaves DOG switch and another
100 pulses will be output in the negative direction with JOG frequency. Please refer to state 6 for
the timing diagram of this function. (The function supports ES2/EX2 series of V1.40 or above, and
SS2/SX2 series of V1.20 or above.)
11. Timing Diagram:
State 1: Current position at right side of DOG switch, pulse output in reverse, limit switch disabled.
