ERROR MESSAGES
There are 5 error types that can be detected by ONDRIVE motor driver. Possible reasons and
recommended solutions for those errors are listed below:
Error Message Description Possible Reasons and Solutions
Pressure Fault An overload situation has been
detected in the door due to a
mechanical blockage, an
obstacle prevention or any
problem due to connection
faults.
1)
Check if the door has a
mechanical problem or not.
2)
Check the encoder
connections. Are the color
codes correct and connected to
the right pin?
3)
Check motor phase cables.
Are the color codes for each
phase correct? One or more of
them can be disconnected from
connector. Or there can be any
broken or damaged cable.
4)
Check the encoder, it can be
damaged.
Module Error Circuit that includes IGBT
inverter detected a fault due to
overcurrent or overvoltage.
1)
Motor can draw a huge current
due to a fault in connectors,
windings or cables.
2)
Grid voltage can be high.
3)
Deceleration ramps of the door
can be very short and steep.
4)
One or more of the IGBTs can
be damaged.
5)
Current or voltage detection
circuit can be damaged.
Encoder VCC
Error
Encoder board draws more
than allowed current limit.
1)
Check the encoder connections
and cables.
2)
Encoder can be damaged.
High Vdc Error DC bus voltage increased
above allowed voltage limit.
1)
Grid voltage can be high.
2)
Deceleration ramps of the door
can be very short and steep.
Low Vdc Error DC bus voltage decreased
below allowed voltage limit.
1)
Measure the DC bus voltage.
