Setting method of the output waveform
Set the output waveform as follows. The setting values shown below can be changed during the output.
CH1 PWM output ON time setting 1
(Un\G258 to Un\G259)
Coincidence output point
No.1
CH1 PWM output cycle time setting
(Un\G256 to Un\G257)
CH1 PWM output ON time setting 2
(Un\G260 to Un\G261)
Coincidence output point
No.2
CH1 PWM output cycle time setting
(Un\G256 to Un\G257)
Setting item
CH1 PWM output cycle time setting (Un\G256 to Un\G257)
CH1 PWM output ON time setting 1 (Un\G258 to Un\G259)
CH1 PWM output ON time setting 2 (Un\G260 to Un\G261)
The PWM output starts in the OFF status. When PWM output cycle time - PWM output ON time passes, the PWM output is
turned on. The subtraction of PWM output cycle time - PWM output ON time is performed in the high-speed counter module.
When the result of the subtraction is 0, the PWM output is always on, and when the result of the subtraction is a negative
value, the PWM output is always off.
• When a value other than the setting range described above is set in each of CH1 PWM output cycle time
setting (Un\G256 to Un\G257), CH1 PWM output ON time setting 1 (Un\G258 to Un\G259), and CH1 PWM
output ON time setting 2 (Un\G260 to Un\G261), a normal pulse may not be output.
• By using the calculation formula of PWM output ON time = PWM output cycle time  Duty ratio (%)  100,
the PWM output ON time can be calculated based on the duty ratio specified by users.
■Setting condition
Set a value that satisfies all the following conditions. Otherwise, the PWM output is always off.
• PWM output cycle time setting > 0
• PWM output ON time setting > 0
• PWM output cycle time setting  PWM output ON time setting (When this relation is =, the PWM output is always on.)
Setting details
Set the time of one cycle of the output pulse in the range of 0 to 2147483647.
Set the value in increments of 0.1s.
• Set the ON time of the output pulse from the PWM output point No.1
terminal (EQU1) in the range of 0 to 2147483647. Set the value in
increments of 0.1s.
• When no pulse is output from the PWM output point No.1 terminal (EQU1),
set 0.
• Set the ON time of the output pulse from the PWM output point No.2
terminal (EQU2) in the range of 0 to 2147483647. Set the value in
increments of 0.1s.
• When no pulse is output from the PWM output point No.2 terminal (EQU2),
set 0.
