[PE0] [PE1] signals: Pressing complete output (backward end / forward end)
● Turns ON when "pressing complete" is determined during pressing operation.
● Turns OFF if no contact can be made.
→ Refer to “ Pressing Operation (page 4-20)” for details about pressing operation.
[*ALM] signal: Alarm output
● Turns ON when the ELECYLINDER is in normal status.
Turns OFF when an alarm occurs.
● Always monitor the *ALM signal using the master device.
If it turns OFF, immediately take appropriate safety countermeasures with the
equipment as a whole.
→ For details, refer to "7.4 Troubleshooting by alarm groups".
Signal input time constant
In order to prevent mis-operation due to chattering or noise, [ST0], [ST1] and [RES] signals are
set with a 6 ms input time constant.
For signals less than 6 ms the device will not consistently recognize the signal, so input signals
continuously for 6 ms or longer.
