Special Data Registers Of Output Axis 2 (Corresponding To Y4); Control And Monitor Output Channels Of Output Axis 3 - INVT IVC2H Programming Manual

Programming manual of IVC series small PLC
Address Name
SM274 Pulse output monitor
Pulse output completion
SM74
interrupt enabling control
SM340 Clear function valid
Clear signal designated
SM341
element valid
SM342 Origin return direction
SM343 Forward rotation limit
SM344 Reverse rotation limit
Logic reverse rotation of
SM345
near-point signal
Logic reverse rotation of
SM346
zero-point signal
Locating instruction in
SM348
drive
Note: When SM340 is set, the corresponding default clear signal Y14 of the output axis will send 1 CLR pulse output at origin return
arrival and the pulse width is 20ms+1 scan cycle. If the default clear signal is used in other ways, reset valid clear signal to disable
the function.

Note:
1. SD342~SD345 can be changed by users according to needs. Please ensure to assign the value before driving the locating
instruction. Changing above parameters when executing the locating instruction may affect correct execution.
2. The base speed must be smaller than 1/10 of the Max. speed; otherwise, no pulse output. If the speed of the locating instruction
is lower than the base speed or higher than the Max. speed, no pulse output, either.
Control and monitor output channels of output axis 3 (corresponding to Y5)
function when resetting
Used to monitor the state of Y4 high-speed pulse output channel, ON when busy,
OFF when ready
Enable Y4 high-speed pulse output completion interrupt when setting; disable pulse
output completion interrupt when resetting
Applicable to DSZR/ZRN, function on the corresponding axis of Y4: CLR signal
output of origin return instruction is valid when setting; no CLR signal output when
resetting
Applicable to DSZR, function on the corresponding axis of Y4: using corresponding
Y element Y(N) of N in SD346 means clear signal when setting; set Y14 to clear
signal according to the default value when resetting
Applicable to DSZR, function on the corresponding axis of Y4: origin return
direction is forward rotation direction when setting; origin return direction is reverse
rotation direction when resetting
Applicable to DSZR, function on the corresponding axis of Y4: forward rotation limit
arrival when setting; resetting means forward rotation limit non-arrival when
resetting
Applicable to DSZR, function on the corresponding axis of Y4: reverse rotation limit
arrival when setting; reverse rotation limit non-arrival when resetting
Applicable to DSZR, function on the corresponding axis of Y4: negative logic
processing when setting (near-point signal is ON when inputting OFF); positive
logic processing when resetting (near-point signal is ON when inputting ON)
Applicable to DSZR, function on the corresponding axis of Y4: negative logic
processing when setting (zero-point signal is ON when inputting OFF); positive
logic processing when resetting (zero-point signal is ON when inputting ON)
Used to monitor the state of Y4 high-speed pulse output channel when executing
DSZR, ON when busy, OFF when ready
Name
Used to calculate and store absolute position. Each time the position
instruction is executed, calculate and update SD340~SD341 according to
SD164~SD165 and direction signals. When starting the machine and reading
absolute position data from servo drive, store the acquired data (32-bit long)
into SD340.
The Max. speed when the output axis executes the locating instruction,
range: 10~200000, unit: pulse
The base speed when the output axis executes the locating instruction (below
1/10 of the Max. speed)
The ACC/DEC time when the output axis executes the locating instruction,
range: 50~5000, unit: ms
When SM341 is set, the corresponding Y element Y(N) of N in the element is
clear signal
Applicable to DSZR, function as the crawling speed when executing the
instruction
Applicable to DSZR, function as the origin return speed when executing the
instruction
Applicable to PLS, used to detect the envelope output stage
