Function
Thesignal OH3 is derived from a comparator with hysteresis.Theswitch-off threshold is 150 îš•Cand
is fixed. The hysteresis is also fixed and amounts to 15 K (i.e. the reclosing temperature is 135 îš•C.
This monitoring is only effective for the thermal sensor specified by Lenze as it is included in the
standard Lenze servo motor. The Sub-D connectors X7 or X8 serve as inputs.
Stop!
Only oneof theinpputscanbeused.Theotherinput must not beassigned (must remainopen).This
monitoring is activated by default setting. This means that the monitoring reacts if no Lenze servo
motor is used.
