Applicable to Various Systems, Including Servomotors
PLd/Safety Category 3(ISO13849-1)
1. Monitoring with Proximity Sensors
A redundant safety system can be configured by using two E2E Proximity Sensors. The fault diagnosis function of the G9SX-LM provides a high level of safety.
* Use only the DC 3-wire PNP type E2E.
2. Speed Monitoring Matched to the Function for Each Operating Mode
In normal operating mode, standstill is monitored to unlock the door.
In maintenance mode, low-speed operation is monitored to allow maintenance work.
3. Applicable to Servomotors
Because the drive rotation is directly monitored, the G9SX-LM can also be used with Servomotors.
