Temperature sensor interface

Description
The ET200pro FC-2 has a temperature sensor input that allows the real-time temperature of
the motor to be detected by the converter. You can connect a PTC, KTY84 or a bimetal
switch to the temperature sensor input.
The connections for the temperature sensor sensor to the motor temperature monitor is
integrated into the HAN Q motor connector on the front of the converter.
Dangerous voltages
The motor temperature monitor function is connected to the line supply potential and
therefore dangerous voltage are possible on the sensor connections.
The frequency converter must be powered down and all power cables disconnected from
the frequency converter before the motor temperature sensor can be connected, or
disconnected.
4.8.3

Interface to the motor holding brake

Description
A motor holding brake can be controlled using the ET 200pro FC-2. The electrical connection
between the converter and the brake is established by plugging the motor cable into the
converter. Use of the motor holding brake is optional. Only a 180 V DC (@ 400 V AC mains
voltage) can be used.
Assignment of wiring from the temperature sensor and motor holding brake in the motor
plug, see Table 4-4 Assignment of the main power connections on the frequency converter

Wiring the ET200pro system

Overview
Communication and auxiliary voltages are routed with standard connectors through the
interface module (or power modules) and the backplane bus to the converter and do not
have to be considered here.
The converter is rated for direct operation on TN and TT line supply systems with a
grounded PEN conductor with a rated voltage of 3 AC 400 V. In the case of systems where
