Product Description:

The 131F1796 Frequency Converter is designed for variable speed control of 3 phase motors operating at 380 – 480 V AC. It delivers a typical shaft output of 1.5 kW and ensures reliable motor performance under diverse load conditions. This converter is equipped with compact chassis options and enclosure types suited for industrial environments.

This 131F1796 frequency converter supports continuous and intermittent operation across a voltage range of 3 × 380 – 480 V. For 3 × 380 – 440 V, it provides a continuous current of 4.1 A and intermittent current of 4.5 A. At 3 × 441 – 480 V, it supplies 3.7 A continuously and 4.1 A intermittently. The continuous apparent power output is rated at 2.8 kVA while the intermittent output reaches 3.1 kVA. The corresponding continuous output current at 460 V AC is 2.7 A with intermittent output reaching 2.9 A. The converter requires a maximum input current of 3.7 A (continuous) and 4.1 A (intermittent). The starting torque and overload torque support up to 110 % for 60 seconds which makes it suitable for demanding motor startups. The torque rise time is just 10 ms that ensures fast and efficient dynamic motor response. This model has undergone vibration testing up to 1.0 g and can operate in environments with up to 93 % relative humidity (non condensing).

The 131F1796 frequency converter features Safe Torque Off (STO) functionality on Terminal 37 fixed with PNP logic. The input voltage range for STO is 0 – 24 V DC. The maximum voltage allowed on the input is 28 V DC. The typical input current at 24 V is 50 mA rms and at 20 V is 60 mA rms. The input capacitance is specified at 400 nF. This safety feature ensures secure motor shutdown without using mechanical contactors.

Frequently Asked Questions about 131F1796:

Q: How does the 131F1796 Frequency Converter maintain reliable torque output during high-inertia motor starts?

A: It supports a starting and overload torque of up to 110% for 60 seconds. This enables controlled motor acceleration under demanding load conditions with minimal voltage drop.

Q: How quickly does the 131F1796 Frequency Converter respond to torque demands during rapid load shifts?

A: It delivers a torque rise time of just 10 milliseconds. This ensures precise and dynamic motor control in fast-acting industrial processes.

Q: What continuous and intermittent performance levels can be expected from the 131F1796 Frequency Converter at higher supply voltages?

A: At 3 × 441–480 V input, it provides 3.7 A continuously and 4.1 A intermittently. The output power reaches up to 3.1 kVA during short peak loads.

Q: How does the 131F1796 Frequency Converter ensure safe motor deactivation in critical safety applications?

A: It integrates Safe Torque Off (STO) on Terminal 37 using PNP logic and a 0–24 V DC input range. This feature disables torque without mechanical contactors, ensuring safe shutdown.

Q: How well does the 131F1796 Frequency Converter handle environmental and mechanical stress in field installations?

A: It operates in up to 93% relative humidity (non-condensing) and withstands vibration up to 1.0 g. This makes it suitable for harsh industrial environments and continuous-duty applications.
