(safety output 1 can be turned ON by operation of
the start input), the solenoid output is OFF.
Solenoid output 1
(Y17)
TEACH mode
When safety output 1 is OFF, the solenoid output is
ON. When safety output 1 is ON, the solenoid output
is OFF.
AUTO mode
When safety output 2 is OFF, the solenoid output is
ON. When safety Output 2 is ready to turn ON
(safety output 2 can be turned ON by operation of
the start input), the solenoid output is OFF.
Solenoid output 2
(Y20)
TEACH mode
When safety output 2 is OFF, the solenoid output is
ON. When safety output 2 is ON, the solenoid output
is OFF.
Warning
The solenoid outputs are not safety output. Do not use these to construct a safety system.
Note. The solenoid output is OFF in each state except Run state.
Caution
Refer to "Chapter 2 PRODUCT SPECIFICATIONS" for specifications of each input and output.
