General programming information
!
 If both the main program and the interrupt program contain code for the same
channel, make sure both are not executed simultaneously.
When a pulse output instruction is executed and pulses are being output, the

pulse output control flag (e.g. sys_bIsPulseChannel0Active) of the corresponding
channel is TRUE. No other pulse output instruction can be executed as long as
this flag is TRUE.
 Set the position control trigger input (X0, X1, X2, X3) in system register 402.
 For the position control trigger input, only the rising edge (TRUE) is detected.
 The instruction cannot be started when a decelerated stop has been requested.
 To restart after stopping the operation, turn the execution condition to FALSE
and then to TRUE again.
 We strongly recommend that you incorporate a forced stop (see page 1021)
option in your positioning program.
 The status of the high-speed counter control flag or pulse output control flag may
change while a scan is being carried out. For example, if the flag is used more
than once as an input condition, different statuses may exist within one scan. To
ensure proper execution of the program, the status of the special internal relay
should be copied to a variable at the beginning of the program.

stop.
