OLED Message
Description
Corrective Action
23
Ambient
Temperature High
Ambient Temperature too
High
Measured temperature around the drive is above the operating limit.
Ensure the drive internal cooling fan is operating, cooling airflow
path to and from the drive is not restricted. Increase the cooling
airflow to the drive
Reduce the effective switching frequency or reduce the load on the
motor.
24
Exceed max torque
Over-Current Error
Current Monitoring Function has detected current levels above the
normal operating condition for the application.
Check mechanical load has not changed and that the load is not
jammed or stalling.
For pump application check for potential pump blockage
For fan applications check airstream to and from the fan is not
restricted
25
Output torque too
low
Under-Current Error
Current Monitoring Function has detected current levels below the
normal operating condition for the application.
Check for mechanical breakages causing loss of load (e.g. belt
break).
Check motor has not become disconnected from the drive.
26
Drive Output Fault
Drive output fault
Drive output fault. Refer to your Beijer office.
29
Internal STO Error
Hardware Circuit Error
Hardware STO Input Circuit Fault. Refer to your Beijer office.
40
Autotune fail 1
Autotune Failed, Ensure
the motor is correctly
connected and free from
faults
Measured motor stator resistance varies between phases. Check the
windings for correct resistance and balance.
41
Autotune fail 2
Measured motor stator resistance is too large.
Check that the
power rating
corresponds to the
power rating of the
connected drive.
42
Autotune fail 3
Measured motor inductance is too low.
43
Autotune fail 4
Measured motor inductance is too large.
44
Autotune fail 5
Measured motor parameters are not
convergent.
45
Incorrect Supply
Phase Sequence
L1-L2-L3 Phase
sequence is incorrect
Applies to IP20 and Frame Size 8 drives only, indicates that the
phase sequence of incoming voltage is incorrect.
48
Feedback Pressure
Low
Low Pressure Detected by
Pipe Fill Function
Check the pump system for leaks for burst pipes.
Check the Pipes or hoses.
49
Output Phase Loss
Output (Motor) Phase Loss
One of the motor output phases is not connected to the drive.
50
Modbus Comms fault
Modbus communication
error detected
A valid Modbus telegram has not been received within the watchdog
time limit in P5-05. Check the network master operating and cabling.
52
Option Module Fault
Communication Module
Fault
Check that communications I/O- module is correctly inserted. Check
the pins of the option board.
53
IO Card Comms fault
IO card comms trip
Check that I/O- module is correctly inserted. Check the pins.
54
BACnet Comms fault
BACnet comms loss trip
A valid BACnet telegram has not been received within the watchdog
time limit set in P5-05. Check the network master / PLC is still
operating. Check the connection cables.
Increase the value of P5-05 to a suitable level.
