Trouble shooting
If the power supply to the machine should be cut while it is operating, the
program unit has a memory which stores the program selected for about 3
to 5 minutes.
Within this period the machine will restart automatically once the power
supply is restored.
Indication of faults/errors
Faults/errors in the program or machine are indicated by a numerical error
code followed by the letter E flashing on and off on the control panel
display.
In the case of error codes 01E, 02E, 03E and 14E, an attempt to restart the
machine may be made as soon as the fault/error has been remedied,
without the power supply being switched off. For the other error codes, a
service engineer must be called.
WARNING
When working on the motor control unit
The voltage at test points 1 - 4 (TP1 - 4) has a potential difference of
up to 300 V in relation to incoming neutral and ground. Because of
this, be careful when measuring. Use ungrounded oscilloscopes.
The motor functions as a generator when decelerating. If the motor
has not stopped, high voltages may be present on the motor control
circuit board even though the power supply to the machine has been
disconnected.
