Festo P.BE-MTR-DCI-DN-EN en 1209a
Fault Possible cause Remedy
DEVICENET INIT NO
PARAMETER ERROR Essential bus parameters not set.
– MTR-DCI not on the bus. • Set bus parameters (see sec-
tion 5.2.7):
– MAC-ID
– Bit rate
– I/O Data length
HARDWARE ERROR Device fault (EEPROM defective, or
user data damaged) • Contact Festo Service.
I2t-ERROR Current monitoring i 2 t.
– The drive is blocked
• Check the drive mechanism.
HOMING ERROR Error during homing
– Homing run interrupted
– Homing switch defective • If necessary, check the function of
the homing switch.
• It is essential that you repeat
homing.
LOAD-POWER-DOWN Voltage monitoring
– Load voltage too low
MTR-DCI 32/42/52: U < 18 V
MTR-DCI 62: U < 34 V
– Voltage drops under load
• Check the power supply:
– Power supply unit too weak?
– Supply line too long?
MOTOR STOP Error during the positioning proced-
ure
– A positioning procedure has been
aborted on the control panel with
EMERG.STOP (button “Menu”).
• Acknowledge the error on the
control panel with “Enter”
OVERHEATING Overheating
(Operating temperature > 80 °C).
– Temperature of power stage too
high.
– Ambient temperature too high
• Check:
– That the limits are complied
with (motor characteristic
curves),
– the mechanical parts e.g. for
stiffness.
• If necessary, reduce the ambient
temperature.
PLEASE ENFORCE
HOMING RUN When starting a position set:
– A valid homing process has not
yet been conducted.
– Due to a logic voltage failure the
reference position has been lost.
• Carry out homing.
