Supplement to pulse output operation
When outputting pulses with the PLS+SIGN (direction output) method, pulses will be output
approx. 300 μs later after the output of direction signal (SIGN). (The characteristics of a motor
driver are considered.)

Precautions during programming
● This instruction cannot be executed when a control active flag corresponding to each
channel is ON.
● When describing the same channel in both the normal program and the interrupt program, be
sure to program not to execute them simultaneously.
● Select "Pulse output" for the channel setting corresponding to the system register no. 402.
● When rewriting during RUN is performed during the operation, the pulse output stops while a
program is being rewritten.
● Even if the control code is changed after starting the instruction, the change is invalid. It does
not affect on the operation.
● When the frequency is changed to a value outside of the settable range after executing the
instruction, the operation is performed with the minimum or maximum value in the
specification range without causing an operation error.
● For details of the allocations of I/O and flags, refer to "Allocation of Memory Areas".

Description
The setting range of the settable change speed varies according to
the setting of the initial speed as shown in the table below.

speed
When the initial speed is set to low speed, it is corrected to 22 kHz
even when specifying a value exceeding K22000 for the change
speed.
Target value (absolute value)
It is used when setting the target value match stop mode. (Absolute
only)
Specify the target value in the following range. If a value outside of
the range is specified, the number of pulses different from the
specified value is output. When specifying the no counting mode, the
target value setting is ignored.
