5.9 Motor temperature
Temperature monitoring forms part of the configurable error- and warnin
behavior.
he connected load can be monitored by connectin
a measurin
resistor (motor PTC)
with temperature characteristics according to DIN 44081 or by means of a bimetal
temperature sensor (break contact).
The operation mode of the motor ptc port can be selected via parameter
Operation
Mode Motor Temp.
570 The operation modes described in chapter "Motor Tempera-
ture" of the frequency inverter operating instructions are complemented by the follow-
ing operation modes with the EM-IO-02 expansion module:
Operation mode Function
11 -
EM-MPTC:
warning only
The critical operating point is displayed by the control
unit and parameter
Warnings 269.
12 -
EM-MPTC:
Error-switch-off
Error-switch-off is displayed by message F0400. Error-
switch-off can be acknowledged via the control unit or
the digital input.
13 -
EM-MPTC:
Error-switch-off,
1 min. delay
Error-switch-off according to operation mode 2, delayed
by one minute.
14 -
EM-MPTC:
Error-switch-off,
5 min. delay
Error-switch-off according to operation mode 2, delayed
by five minutes.
15 -
EM-MPTC:
Error-switch-off,
10 min. delay
Error-switch-off according to operation mode 2, delayed
by ten minutes.
The function to be adjusted by parameter
Operation Mode Motor Temp. 570 results in
si
nalin
the overtemperature by the red LED of the frequency inverter, irrespective o
the selected operation modes of the control inputs and outputs.
The operation modes with error-switch-off result in the fault messa
e "FAULT" with
fault number "F0400" being displayed on the control unit KP500.
The fault message can be acknowledged via parameter
