4.1.5 Checking For What Keeps The Mcc From Being Switched On
(1) The system is still in an emergency stop status.
→ Check the connection to make sure that the emergency stop
signal connected to the PSM connector CX4 and the
emergency stop signal (such as *ESP) input to the CNC are
both released.
(2) There is a connector problem.
(a) No terminating connector is attached.
→ Check whether a terminating connector is attached to
JX1B of the SVM or SPM at the end of the connection
chain.
(b) The interface cable between JX1B of the power supply
module and JX1A of the SVM or SPM is defective.
→ Check whether the interface cable is faulty.
(3) The power for driving the magnetic contactor is not supplied.
→ Check the voltage across the both ends of the coil of the
magnetic contactor.
(4) The relay for driving the magnetic contactor is defective.
→ Check that a circuit between pins <1> and <3> of connector
CX3 is closed and opened.
