The instruction will occupy two pulse output points at the same time ( =K0 uses Y0+Y1; =K1 uses Y2+Y3).
The example below uses (Y0+Y1) output axes for the description of this instruction. Since the output axes (Y2+Y3)
have the same function, the devices between parentheses () indicate those are corresponding to (Y2+Y3).
M9340/M9360 indicates that Y0/Y1 is occupied by a positioning instruction. (M9380/M9400)
Any instruction uses the Y0/Y1 to generate pulse string and it is already activated, that will occupy the resource of
Y0/Y1 axis consistently. However, turn the condition contact of this activated instruction “OFF” could release the
resource.
Thus, before to activate this instruction should conrm the states of M9340 and M9360 both.
If the M9340 = “ON”, that indicates the Y0 is BUSY to generate pulse string or other instruction still occupies the
resource of the Y0. Even though, the condition contact of this instruction is “ON”, the instruction will not execute.
If the M9360 = “ON”, that indicates the Y1 is BUSY to generate pulse string or other instruction still occupies the
resource of the Y1. Even though, the condition contact of this instruction is “ON”, the instruction will not execute.
If both the M9340 and M9360 = “OFF”, that indicates the Y0 and Y1 are in the READY status (these resources are
free to use), the Y0+Y1 can be used for this instruction.
M9341/M9361 is the pulse output monitor of the Y0/Y1. (M9381/M9401)
When the Y0/Y1 is generating pulses, both of the M9341/M9361 = “ON”.
M9342/M9362 is the positioning completed ag of the Y0/Y1. (M9382/M9402)
When the positioning instruction is completed, both of the M9342/M9362 = “ON”.
Turn “OFF” the condition contact of the completed instruction will lead the ag M9342/M9362 “OFF”.
M9343/M9363 is the positioning abnormal stop ag of the Y0/Y1. (M9383/M9403)
Trigger any related compulsive stop ag or the forward / reverse limit switch during the unnished Y0+Y1
positioning function, will cause both the Y0 and Y1 stop to generate pulses and let the M9343/M9363 = "ON" to
indicate this stop is abnormal.
Turn “OFF” the condition contact of the activated instruction will lead the ag M9343/M9363 “OFF”.
M9345/M9365 is the ag to stop the Y0 and Y1 generating pulse string (by gradually slow down). (M9385/M9405)
When either the M9345 or M9365 is turned “ON”, the pulse generating at both the Y0 and Y1 will gradually slow
down then stop.
After the stop signal is discontinued, to make the axes move must release the positioning instruction then restart.
M9346/M9366 is the ag to imminently stop the Y0 and Y1 generating pulse string. (M9386/M9406)
When either the M9346 or M9366 is turned “ON”, the pulse generating at both the Y0 and Y1 will stop imminently
(without to slow down).
After the stop signal is discontinued, to make the axes move must release the positioning instruction then restart.
Forward / Reverse limit switch (under the “Positioning Parameter Setup” of the Ladder Master S).
When either one of the related forward / reverse limit switch is activated, that limits both the actions of the Y0 and
Y1 to make the motors slow down and stop.
DD9350/DD9370 display the positioning current speed of the Y0/Y1. (DD9390/DD9410)
When the instruction is active, those 32-bit special registers show the present value of operating speeds
(by user unit).
DD9354/DD9374 display the positioning location (present value PV) of the Y0/Y1. (DD9394/DD9414) (by user unit)
When the power is turned from “OFF” to “ON”, the initial value of those 32-bit special registers are 0.
Afterward, to operate any related positioning control instruction will affect to the contents, they indicate the location
of the Y0 and Y1 (by user unit).
S
During the instruction is in operation, to change any related parameter will be regarded as invalid. Therefore, all the
necessary data at the parameter block should be set up completely before it starts.
When this instruction completes the movement to the target point at both axes, that will let the positioning
completed ag M9382 and M9402 both = “ON”.
If the condition contact M0 turns “OFF” during the pulses are output, the movement of both axes will be gradually
slow down then stop. Thus, that will not to turn the positioning completed ag M9382 or M9402 “ON” neither.
The operation of this instruction will not be affected by the content values of the D9380~D9384, D9388,
D9400~D9404, D9408, D9420~D9424, D9428, D9440~D9444 and D9448.
When the distance to be moved at the X-axis and Y-axis are both equal to zero (Start-up point = Target point), this
instruction will not execute.
