overtemperature < 100 ms ю ю ю ¨ Motor overtemperature l Check if the motor cooling via the motor housing
is impeded as a result of deposits, etc. (if
necessary, clean the motor).
l Are there any other sources of heat near the
motor that may additionally increase the ambient
temperature and thus lead to a reduced heat loss
dissipation?
l Check the controller settings, poor settings will
lead to an unnecessary heat generation.
l Reduce the load torque of the motor.
l Check the setting of the temperature sensor.
l Check the resolver and encoder cable for an open
circuit.
l Check the resolver position adjustment.

electronics < 100 ms ю ю − − Overtemperature/undertemperature of
controller l Check if the controller has been correctly
mounted into the control cabinet:
– The heatsink must be connected with a surface
as large as possible to the control cabinet
housing.
– Are there any other sources of heat near the
controller that may increase the ambient
temperature of the inverter?
l Check if the ventilation slots of the controller are
polluted or obstructed. Clean them, if necessary.
l Optimise the controller settings (poor settings will
lead to an unnecessary heat generation).
l Check the resolver position adjustment.
l Reduce the load torque of the motor.
5 7392 SINCOS supply error < 5 msec þ − − − Resolver or SINCOS encoder error, reliable
detection only possible after approx. ½
motor revolution, if necessary l Check resolver plug connection.
l Check resolver cable for cable breakage, short
circuit.
l Check pin assignment of resolver cable plug.
l Correct encoder parameters.

the user. Send servo positioning controller to your
Lenze representative.
