Operands:
Module: Module number Axis: Output axis number TarPulse: Target number of output pulses
TarSpeed: Target output frequency Done: Completion flag Error: Error flag
ErrCode: Error code
Explanations:
1. This instruction is available for ES2/EX2 (FW V4.02 or later) and ES2-E (FW V1.48 or later).
For ISPSoft, we recommend using software version 3.16 and above. When En setting is set to
ON, this instruction would be effective. Once the setting changes to OFF, Output pulse would
be terminated immediately. WPLSoft does NOT support this instruction.
2. Module sets the serial number of modules at the right of the PLC. The first one is number 0,
the second one is number 1 and so on. Whatever modules at the right of the PLC must be
numbered. The maximum number is 8. The instruction is exclusive to the PU modules at the
right of the PLC. If the specified module is not a PU module, the error flag Error will change to
ON.
3. Axis sets the output axis number for the specified PU module. The setting values 1~2
represent the axis1~axis2 output of the specified PU module respectively. If the PU module
has no corresponding axis number for output, the error flag Error will change to ON.
4. TarPulse sets the number of output pulses. The pulse number is a positive signed 32-bit value.
When the value is 0, it means the output is always being performed, the number of output
pulses is not limited and the output is not stopped until the instruction is disabled. When the
value is less than 0, the PLC automatically uses 2's complement to transform the value into a
positive integer as the number of output pulses.
