Stopping
Normal production stops are performed by pressing Stop. Access through the
safety gate is initiated by pressing the Gate Unlock Request. The Y32 output of
the GLT safety relay turns OFF, which commands the PowerFlex® drive to
bring the motor to a stop. After the configured time delay (8 seconds) expires,
the GLT safety outputs turn off, and the gate becomes unlocked. After you
leave the cell and close the gate, press Reset to lock the gate and return the
machine to a production state.
The circuit meets the safety requirements up to Category 3, Performance
Leveld in accordance with ISO 13849-1 and SIL CL 2 in accordance with IEC
62061.
