T 8 Error detetion and trouble sho oting
8.3.1 Monitoring funtions - explanations
Overcurrent HW This monitoring function checks, if the motor current exceeds the output peak
current amplitude by more than 30%.
DC link This monitoring function checks the voltage in the DC link. In case the voltage
drops below an ad justed limit value, the error„DC link undervoltage“ is displayed
by the controller. In case the voltage exceeds an adjusted value, the error „DC link
overvoltage“ is signaled from the controller and there is an immediate pulse inhibit.
Temperature of
controll er PCB
This monitoring function checks the temperature of the controller PCB. There is a
distinction between warning and error thresholds. When exceeding the warning
threshold (but falling below the error threshold) a warning is displayed only. When
exceeding the error threshold besides the error message there is also an immediate
pulse inhibit released.
Temperature heat
sink
This monitoring function checks the temperature of the heat sink. If the error
threshold is exceeded, an error message is displayed and pulse inhibit is activated
immediately.
Temperature
motor
This monitoring function checks the temperature of the motor.
• If the I
2
t-threshold is exceeded, the warning „I
2
t-threshold“ is displayed by
the controller.
• If the I
2
t-value is exceeded by 100%, the error „I
2
t-overload“ is displayed by
the controller.
• If the temperature threshold 1 is exceeded the warning „temperature
threshold 1 exceeded“ is displayed by the controller.
• If the temperature threshold 2 is exceeded the warning „temperature
threshold 2 exceeded“ is displayed by the controller.
• The smallest value the PTC-sensor (KTY84) can provide is -30°C. In case this
temperature is exceeded or a short-circuit occurs at the sensor, the error
„Short-circuit temperature sensor“ is displayed.
• The highest value the PTC-sensor (KTY84) can provide is +260°C. If this
temperature is exceeded or the sensor is not connected, the error
„Temperature sensor not connected“ is signaled by the controller.
Position controller This monitoring function checks the statical/dynamical position deviation limit. In
case the statical/dynamical position deviation error is greater than the adjusted
position deviation error limit, there is an error message „position deviation error
statical“ or „position deviation error dynamical“. After monitoring time (position
deviation time), additionally an error message is displayed and there is an
immediate pulse inhibit.
