9. Diagnostics and fault clearance
Remedy:
1. Check the NC control logics for activating the drive.
2. Remedy the malfunction in the power supply unit.
"External power supply voltage error"
Different optional plug-in modules have DC-decoupled inputs and out-
puts. An external power supply must be applied for proper operation of
these inputs and outputs. If this voltage lies above the permissible level,
the above error message will be signalled.
Remedy:
Check the external power supply. Refer to the relevant connection
diagram and project planning documentation for the voltage range and
tolerance (see project planning documentation, Doc. No.: 209-0069-
4317-00).
"Amplifier overtemperature warning"
The temperature of the heatsink in the drive controller has reached the
maximum permissible level. The drive will follow the given command
value for 30 seconds. This permits the axis to be brought to a halt by the
NC control without endangering the process (e.g. completing a machin-
ing operation, retreating from an area where collisions might occur, etc.)
After 30 seconds, the drive will react according to the parameter "error
reaction" (P-0-0007), see Section 7.1.
Cause:
1. Failure of the unit’s internal cooling system
2. Failure of the cabinet air conditioning system
3. Insufficiently dimensioned cabinet air conditioning.
Remedy:
1. If the cooling system is defective, change the controller.
2. Restore the cabinet air conditioning function.
3. Check the cabinet dimensioning.
"Motor overtemperature warning"
The motor has risen above the permissible temperature. The drive will
follow the given command value for 30 seconds. This permits the axis to
be brought to a halt by the NC control without endangering the process
(e.g. completing a machining operation, retreating from an area where
collisions might occur, etc.)
After 30 seconds, the drive will react according to the parameter "error
reaction", see Section 7.1.
Cause:
The motor was overloaded. The effective torque demanded from the
motor was above the permissible nominal torque for too long.
Remedy:
Check the motor dimensioning. For plants which have been in operation
for some time, check whether the drive conditions have changed (e.g.
contamination, friction, moved masses, etc.)
