Figure 13 ADL300 specific reference design to use a single contactor onto the motor.
Figure 13 is a more specific ADL300 design case using single contactor and AC motors.
According to previous prescriptions it can be noticed that:
1. The system control unit uses both K3M contactor and ADL300 safety integrated mechanism
2. The System control unit will still be in charge for controlling K2M and K3M which in turn act on
both SAFETY ENABLE and ENABLE commands.
3. SAFETY OK relay is monitored by means of a series connections onto ENABLE (ENHW).
4. DRIVE OK is monitored by means of of a series connection onto L1 main command.
