A069
Current input < 4mA
Description
A066: REF Current input (4
20mA) lower than 4mA
A067: AIN1 Current input (4
20mA) lower than 4mA
A068
: AIN2 Current input (4
20mA) lower than 4mA
A069:
XAIN5 current input (4
20mA) lower than 4mA
Event
A current value lower than 4 mA has been detected over one input (REF, AIN1, AIN2, XAIN5)
set with the following range: 4
20mA.
Possible cause
•
Wrong setting of SW1 on the control board (except for A069). (for further detail, please
contact ENERTRONICA SANTERNO
’s Customer Service)
•
Signal cable disconnected.
•
Failure in the current signal source.
Solution
1. Check correct setting of switches
SW1
(except for
A069
).
2. Check if the current signal cable is correctly connected to the relative terminal.
3. Check the source of the current signal.

Parameter Upload/Download Error from Keypad to Drive
Description
Upload/download failed, one of the controls of the parameter consistency detected a fault.
Event
A communication error occurred while uploading/downloading the programming parameters
from the keypad to the drive.
Possible cause
Temporary interruption to the serial link between keypad and control board.
Solution
Check the connection between the keypad and the control board, reset the alarm and perform a
new upload/download procedure.
A074
Overload
Description
Drive thermal protection tripped.
Event
The output current has been exceeding the drive rated current for long time periods.
Possible cause
•
Current equal to
Ipeak
+ 20% for
3 seconds
, or
•
Current equal to
Imax
for
60 seconds
•
Current reduction due to overtemperature (parameters
C809
,
C810
) has caused speed to
drop below the value set in
C800
(see section 2.6.9).
Solution
Check the drive current output during ordinary operation (
M026
, see section 2.5.2); check the
mechanical conditions of the connected load (load locked / overload).
A075
Motor Overheated
Description
Motor thermal protection tripped.
Event
The software motor thermal protection tripped. Output current has been exceeding the motor
rated current for long periods.
Possible cause
•
Poor mechanical conditions of the connected load
•
Wrong setting of parameters in the Motor Thermal Protection Menu, section 2.6.8).
Solution
1. Check mechanical conditions of the connected load.
2. Check parameters
C265
,
C266
,
C267
in
the Motor Thermal Protection Menu, section 2.6.8.
