Product Description:
The 134X3042 Frequency Converter from Danfoss provides a shaft output of 0.37 kW with a protection rating of IP20. This unit supports three phase input and maintains high operational accuracy in various applications.
This 134X3042 frequency converter features continuous output current of 2.2 A at 3 x 200 – 240 V and intermittent current of 3.5 A for 60 seconds overload. The continuous output power is 0.9 kVA at 230 V AC. The maximum cable size for mains, motor and brake connections is 4 mm² (12 AWG). The unit's estimated power loss at rated maximum load is 29.4 W. Its physical weight is approximately 2.3 kg (5.1 lb) that allows easy integration into systems with limited space. The starting current of the model is capped at 200 % for a duration of 1 second. The torque rise time in VVC+ mode is limited to a maximum of 50 ms that ensures fast motor response. The ambient operating temperature at DPWM switching mode supports up to 55 °C with derating and up to 45 °C at full constant output current. STO inputs are available on terminals 37 and 38 with voltage range 0 – 30 V DC. The input current for each pin must be a minimum of 6 mA. The voltage below 1.8 V DC is considered low and above 20 V DC is considered high. The inputs support maximum input voltage up to 30 V DC.
The 134X3042 frequency converter draws a continuous current of 1.8 A and supports a short overload of 2.9 A for 60 seconds. The converter maintains high efficiency rated at 96.4 %. The speed accuracy of the converter in open loop mode is ± 0.5 % of the nominal speed while in closed loop operation, it improves to ± 0.1 %.
Frequently Asked Questions about 134X3042:
Q: How does the Danfoss 134X3042 frequency converter support precise motor control in varying loop configurations?
A: It maintains ±0.5% speed accuracy in open loop and improves to ±0.1% in closed loop. This ensures reliable performance across demanding precision applications without feedback instability.
Q: What integration factors should be considered for thermal limits when operating the 134X3042 converter in high ambient environments?
A: It supports full output current up to 45 °C in DPWM mode and allows derated use up to 55 °C. This provides thermal flexibility while maintaining protection and operational stability.
Q: How does the 134X3042 frequency converter ensure rapid motor torque buildup in dynamic load changes?
A: Its VVC+ mode limits torque rise time to 50 ms, ensuring fast acceleration response. This is critical in applications where load changes must be handled without delay.
Q: What protections are offered by the STO inputs on the Danfoss 134X3042 for safe torque shutdown scenarios?
A: The STO functionality on terminals 37 and 38 ensures safe motor disable through standard low-voltage control logic. Input voltage detection follows strict thresholds to prevent false state activation.
Q: How can engineers manage input wiring for mains and braking systems with the 134X3042 frequency converter?
A: It accepts cable sizes up to 4 mm², suitable for most low-power drive systems. This simplifies wiring compatibility while maintaining safe connection standards for input and output paths.
