2MOVITRAC® LTP-B/LTXThermal motor protection
2 MOVITRAC® LTP-B/LTX
2.1 Thermal motor protectionThermal motor overload protection shall be provided by one of the following means:• NEC compliant installation of a motor temperature sensor, see also section "Motor
temperature protection (TF/TH)" in the chapter "Electrical Installation" of theoperating instructions.
• Using internal thermal motor overload protection according to NEC (NationalElectrical Code, US). Thermal motor overload protection can be activated viaparameter P4-17.
• Implementing external measures to ensure thermal motor overload protectionaccording to NEC (National Electrical Code).
2.1.1 ParameterThe following additional parameter was added to MOVITRAC® LTP-B/LTX inverters toimplement internal thermal motor protection according to NEC:• P4-17 Thermal motor protection according to NEC
• 0 / disabled• 1 / enabled
2.1.2 Functional principleThe motor current is accumulated in an internal memory over the course of time. Theinverter goes to fault state as soon as the thermal limit is exceeded (I.t-trP). Once the output current of the inverter is less than the set rated motor current, theinternal memory is decremented depending on the output current.• When P4-17 is disabled, thermal memory retention is reset upon shutdown or power
loss.• When P4-17 is enabled, thermal memory retention is maintained upon shutdown or
power loss.
INFORMATIONOnly the fuses mentioned in chapter "UL compliant installation" of the operatinginstructions shall be used for UL compliant installation.

4.1 Thermal motor protectionThermal motor overload protection shall be provided by one of the following means:• NEC compliant installation of a motor temperature sensor, see also section "Motor
temperature protection (TF/TH)" in the chapter "Electrical Installation" of theoperating instructions.
• Using internal thermal motor overload protection according to NEC (NationalElectrical Code, US). Thermal motor overload protection can be activated viaparameter P41.Note: This function is available with firmware 1.1 and later.
• Implementing external measures to ensure thermal motor overload protectionaccording to NEC (National Electrical Code).
4.1.1 ParameterThe following additional parameter was added to MOVITRAC® LTE-B inverters toimplement internal thermal motor protection according to NEC:• P41 Thermal motor protection according to NEC
