1) I=input; O=output; NC=NC contact; NO=NO contact (for signal: Closed=high, open=low)
2) Reference ground, term. 19 NE/monitoring module (this may not be connected to the general reference ground,
term. 15)
3) Reference point of the differential input.
The common mode range of the differential input is 24 V with respect to PE potential and
may not be exceeded.
4) Refer to Section 6.4
Note
The drive shuts down and the pulses inhibited after approx. 4 s when the ”heat-
sink overtemperature” switch responds.
The SIMODRIVE 611 feed modules with the control for 1FT5 servomotors are
equipped with an evaluation circuit for the PTC thermistor integrated in the mo-
tor windings.
The motors should be protected from inadmissibly high winding temperatures
using the monitoring combination (trigger temperature, 150°C).
As the drive shouldn’t unpredictably intervene in the cutting process, when the
response temperature is reached, this is only signaled to the SIMODRIVE 611,
centrally via terminals 5.1, 5.2, and 5.3 of the rectifier module.
There is no internal system shutdown function to protect the motor.The user
must ensure that the motor can thermally recover immediately after the
signal output, by appropriately designing the adaptation control. It may be
necessary to shutdown the motor immediately.
A delay time is not permissible.
If the motor is not thermally monitored, then the complete drive could be
destroyed if an overload condition occurs, or if the drive converter was
over–dimensioned.
