35.2 Writing the pulse output control code
The special data register where the high-speed counter and pulse output control code are stored
can be accessed with the system variable sys_wHscOrPulseControlCode. (The system variable
sys_wHscOrPulseControlCode corresponds to special data register DT90052.)
Operations performed by the pulse output control code
 Setting/resetting near home input
Continuing/stopping pulse output (forced stop)

 Enabling/disabling counting operations
 Resetting the elapsed value (software reset) of the high-speed counter
 Clearing high-speed counter and position control instructions (FP0R only)
The control code settings for each channel can be monitored using the system variables
sys_wHscChannelxControlCode or sys_wPulseChannelxControlCode (where x=channel number).
The settings of this system variable remain unchanged until another setting operation is executed.
Description for FP:
Bits 0–15 of the control code are allocated in groups of four. The bit setting in each group is
represented by a hex number (e.g. 0002 0000 0000 1001 = 16#2009).

 Performing a forced stop may cause the elapsed value at the PLC
output side to differ from the elapsed value at the motor input side.
Therefore, you must execute a home return after pulse output has
stopped.
 Setting the near home input is not possible if counting is prohibited or
if a software reset is performed.
