11. CONTROL FUNCTION
B–63683EN/01
190
This function outputs the soft thermal data for a servo motor to the PMC,
using binary signals. The use of these signals can prevent the motor from
becoming overheated, by suppressing the feedrate by applying an
override or other methods, thus enabling continuous, safe operation.
[Classification] Input signal
[Function] Specifies the number of the axis (1 to 8) for which soft thermal data is to
be read, as binary code.
When the signals specify 0 or a value exceeding the number of controlled
axes, soft thermal data will not be read.
[Classification] Output signal
[Function] Notifies the PMC of the soft thermal data for the axis selected using the
soft thermal monitor axis selection signals, as binary code. The valid data
range is 0 to 100 (an overload alarm is issued if it is 100).
[Output condition] When an axis is selected using the soft thermal monitor axis selection
signals, the soft thermal data for that axis is output. Before reading these
signals, at least 32 ms must elapse after inputting the axis selection
signals.
If the axis selection signals specify 0 or a value exceeding the number of
controlled axes, the soft thermal monitor signals are not updated but the
previous data is maintained.
