4. Timing Chart of Safety Circuit for QX-type SEL Controller
A timing chart of the safety circuit for QX-type SEL controller is shown below.
The points in time shown in this timing chart are: “[1] Power on,” “[2] Emergency stop,” “[3] Power on
without cancelling emergency stop,” “[4] Enable operation,” “[5] System shutdown level error,” [6] “Cold
start level error,” “[7] Operation cancellation level error,” “[8] Power on (in combination with cutoff reset
input),” and “[9] Emergency stop (in combination with cutoff reset input).”
[1] Power on
x I/O parameter No. 24, bits 0 to 3 = 0: The RDYOUT output (system I/O) is SYSRDY (PIO trigger
program operation enabled) and the hardware is normal
(emergency stop is not actuated and no hardware errors are
detected).
x I/O parameter No. 44 = 0: The drive-source cutoff reset input is not yet used.
x I/O parameter No. 47 = 3: Output function 301 = READY output (PIO program operation
enabled and no errors of cold start level or higher have
occurred).
200-VAC control power
Normal CPU start
I/O output signal: Port No. 301
Ready output
Rdy (system I/O)
SDN (system I/O)
EMG1, EMG2 (system I/O)
ENB1, ENB2 (system I/O)
Occurrence of secret level error
Occurrence of message level error
Occurrence of operation cancellation level error
Occurrence of cold start level error
Occurrence of system shutdown level error
