9.10 ERROR MESSAGES FROM THE MOTOR DRIVER
The RING RIDERS CPU and the motor driver Commander SE (RIN-392) communicate
through a RS-485 serial interface. The Commander receives control signals from the CPU
and sends status signals.
The Commander generates an alarm message when it detects a malfunction. This
message is instantaneous and remains as long as the malfunction is still present. Then the
message is stored in a stack memory of 10 positions, so the technician can consult the last
ten messages.
If the motion system does not work and the security circuits seem to be OK, you should
check the presence of an alarm message by opening the Main Menu of the Test Mode (see
Section 6.1). If there is an alarm message, the option
MOTION SYSTEM ERROR LOG will
blink at the bottom line of the Main Menu. By selecting this option, the alarm messages will
be displayed on the screen, as well as the last 10 trips of the motor control loop.
If the option above mentioned is not displayed, it means that the CPU is not receiving any
error message in that moment. Anyway, you may consult the previous error messages by
selecting the option
Check error log in the MOTION SYSTEM menu. For diagnosis
purposes, please refer to the manual of the Commander SE, supplied with the machine.
In normal conditions, the last ten messages recorded will be all the same ( UU ) because
this message is generated each time the machine is switched off. However, the message
could be related to an actual problem of the mains supply (i.e. voltage drops or cuts). Any
other message should be considered as a malfunction warning that could be helpful when
asking for technical assistance. The manual of the Commander SE includes a resume of
the possible causes for each error message.
WARNING! If the motor dives has an internal hardware failure, or the communication with
the CPU does not work, the CPU will generate the message Commander faillure or bad
connection . This message can be seen by opening the option Check error log of the
MOTION SYSTEM menu.
