5.2.3 Warning signals
The sector that is referred to as ”Warning”, in the ”Status” menu contains different
warning signals, which are explained in the following.
ƒ DC-bus voltage underrun
The DC-bus voltage has underrun the warning value. The limit values for the warning can
be gathered from the ”Voltage threshold” table ( 23).
ƒ Brake voltage beyond the tolerance range
The voltage for the brake is beyond the warning range that is set (delivery condition
22…26 V).
ƒ Motor temperature exceeded
The motor temperature has exceeded 130°C. A derating is initiated.
ƒ Electronics temperature exceeded
This warning signal indicates that the temperature of the motor electronics has exceeded
the value of 70°C and a derating is initiated.
ƒ
Following error
This warning signal indicates that the deviation between the current actual position value
and position setpoint (the following error) is greater than the following error set.
ƒ Derating
Due to a too high temperature of the motor or the inverter, the output power of the
inverter is reduced, in order to counteract further heating.
