9-1-2 Application Procedure
The outputs listed in the following table can be used as PWM outputs. The outputs terminals that are
used for PWM outputs are also used for normal outputs and origin searches. The same output terminal
can be used for only one of these functions.
For example, if PWM output 1 is used, normal output 5 and the error counter reset for pulse output 1
(when performing origin searches) cannot be used.
9-1-2 Application Procedure
1
PWM outputs 0 to 3 use OUT04, OUT05, OUT14, and
OUT15.
2
• Execute a PWM(891) instruction.
• PWM outputs are stopped with the INI(880) instruc-
tion.
