3.5 Shutdown Messages (400 - 599)
A Shutdown is issued in an emergency situation or when the system or
drives cannot operate correctly. During a shutdown, the control switches
the user program tasks into manual mode, decelerates all motion to zero
velocity, and sets the error bit in the status register.
If the shutdown condition results from an E-stop or drive shutdown
condition, the control also disables the drives, disabling motor torque and
engaging the brake.
A low to high transition on the Clear All Errors bit in the System Control
Register will clear a shutdown. The control automatically sends a 'Reset
Class 1 Diagnostics' command to each drive that has an error.
400 EMERGENCY STOP
Cause:
The Emergency Stop input is active (low). The E-Stop circuit has been
opened due to activation of the E-Stop push button or external logic. All
drives on the ring are disabled.
Remedy:
Release the E-Stop button or correct the error condition. Clear error on
control. Set Emergency Stop input active (high) and restart program.
401 SERCOS Controller Error: %02d
Cause:
The SERCOS communications controller has indicated an error on the
SERCOS ring.
Remedy:
Check the fiber optic connections, the addresses set on the drives, and
the drive configuration.
402 SERCOS Config. Error: see ext. diag.
Cause:
An error in the SERCOS service channel has occurred when the control
was initializing the timing and scaling parameters. The extended
diagnostic (C-0-0124) gives a description of the error. Extended
diagnostics can be viewed by selecting Diagnostics ⇒
⇒⇒
⇒ System in
VisualMotion Toolkit.
Remedy:
If the extended diagnostic indicates a timing error or data limit error,
check the amount of data or drives on the ring and the minimum cycle
time parameter C-0-0099. Otherwise, check the fiber optic connections,
the addresses set on the drives, and drive firmware versions.
