3.2.3 The drives cannot be switched on
-- Is the peripheral connector X11 plugged in?
If the connector is not connected or is incorrectly wired, the message “EMERGENCY
STOP” or “Motion enable” or “Operator safety” is displayed.
-- Has the DSE booted?
If the DSE has booted, the LED on the DSE flashes.
-- Check the E--Stop circuits using the ESC diagnostic tool.
-- Is the VxWorks real--time operating system still running?
-- Is there an encoder error present at any axis?
If there is an encoder error, the controller cancels the RC Ready signal on the MFC
and the brakes are applied.
-- Is there a KSD (KUKA Servo Drive) error message present? Certain errors
(e.g. overcurrent, overvoltage) cause the servo drive module to deactivate the drives
automatically.
