10.2.1 Monitoring functions
Overcurrent
This monitoring function checks, if the motor- or the power supply current is 1.3 times
greater than the output peak current. It serves as a protection against an output-sided
short-circuit.
DC-link
This monitoring function checks the voltage in the DC-link. If the voltage falls under a
fixed, internal value (about 210 V), then „DC link undervoltage“ is signaled from the con-
troller and a warning is displayed. If the voltage exceeds a fixed, internal value (about
825 V) then “DC link overvoltage“ is signaled from the controller and an immediate pulse
inhibit takes place.
Ixt-threshold
This monitoring function checks the heat sink temperature and the current load, whether
it can supply the peak current or the max. rated current, at the moment. If peak current is
not possible, the message “Ixt-threshold 1 exceeded“ is displayed.
Temperature
internal space of
device
This monitoring function checks the temperature in the internal space of the device.
m
If the temperature is greater than the warning threshold, the controller displays a warn-
ing.
m
If the temperature is greater than the permitted temperature of the device‘s internal
space, an error is generated, the error reaction can be set.
Temperature
heat sink
This monitoring function checks the temperature of the heat sink.
m
If the temperature is greater than the warning threshold, the controller displays a warn-
ing.
m
If the temperature is greater than the maximum permitted heat sink temperature of the
device‘s internal space, an error is generated, the error reaction can be set.
Temperature
motor
This monitoring function checks the temperature of the motor. if the I²t-overload of the
controller is displayed.
Only for
KTY84 and PT1000
sensor
If the set temperature threshold 1 is exceeded, then the warning „Temperature threshold
1 exceeded“ is generated by the controller.
If the set temperature threshold 2 is exceeded, then the warning „Temperature threshold
2 exceeded“ is generated by the controller.
If the temperature falls below the minimum measurable value, or if a short circuit occurs
at the sensor, then the error message „Temperature sensor short circuit“ is generated.
If the temperature exceeds the maximum measurable temperature, or if the sensor is not
connected, then the error message „Temperature sensor not connected“ is generated by
the controller.
For all
sensors
If the threshold set (type-specific) in the temperature switch or in the sensor is exceeded,
then the error message „Over temperature“ is generated by the controller and the pulses
are inhibited immediately.
Position
controller
This monitoring function checks the position deviation limit statical/dynamical.
The error message „position deviation statical“ or „position deviation dynamical“ is set, if
the present position deviation statical/dynamical is greater than the set position deviation
limit. After the monitoring time (deviation time) has past an additional error message is
displayed and an immediate pulse inhibit takes place. The reaction time is settable.
