4.16 PWM Output Function
4.16 PWM Output Function
The PWM output function is used to output the PWM waveform from one of the coincidence output 1 to 8 terminals
(EQU1 to EQU8). (Note that the PWM waveform of up to 200kHz is output from the coincidence output terminal 1 or 2.
Up to 2kHz waveform is output from the coincidence output terminal 3 to 8.)
(1) Setting for the PWM output function
To use the PWM output function, select "PWM Output Mode" in the "Operation mode setting" in the switch
setting.
(2) Assignment of the PWM output terminals
• To output the PWM waveform, assign Coincidence output 1 to 8 to the corresponding channel in the
"Coincidence output 1 to 8 channel assignment setting" in the switch setting.
• By using CH1 PWM output assignment (Un\G1300), assign which Coincidence output is used for the PWM
waveform output.
For details, refer to the following:
Page 86, Section 3.4.2 (66)
The following table shows the setting examples of the assignment.

No Coincidence output is assigned as
the PWM output terminal.
CH1 PWM output assignment error
(error code: 1670) is detected since no
Coincidence output is assigned as the
PWM output terminal.

Coincidence output 3 is assigned as the
PWM output terminal.
The operation is performed normally.

H
Coincidence output 3 and 4 are
assigned as the PWM output terminal.
CH1 PWM output assignment error
(error code: 1670) is detected since two
Coincidence output is assigned as the
PWM output terminal.

H
Coincidence output 5 is assigned as the
PWM output terminal.
CH1 PWM output assignment error
(error code: 1670) is detected since the
Coincidence output that is assigned to
CH2 is assigned as the PWM output
terminal.
