Product Description:
The HVAC drive 131F6631 is manufactured by Danfoss with the specific product code FC-102P15KT4E20H1XGXXXXSXXXXAXBXCXXXXDX. It provides six configurable digital inputs with logic levels of 0 to 24 V and its input resistance is specified as 4 kΩ, along with a scan interval of 5 ms. The drive’s two digital outputs are available with maximum load of 40 mA at 24 V DC as well.
The 131F6631 drive features a rated motor power of 20 HP and it requires 380 to 480 V, 3-phase mains supply to operate. It provides a displacement power factor greater than 0.980 and its apparent power is 22.2 kVA, under nominal conditions. The unit’s rated efficiency is up to 98% at full load and its carrier frequency is selectable between 2 kHz and 16 kHz. Its output current in continuous duty is 32 A at 380 to 440 V and at 441 to 480 V the continuous current is measured as 27 A, while its periodic overload current rating is 35.2 A and 29.7 A, respectively. This 131F6631 drive supports 110% overload for 60 seconds every 600 seconds and its power loss under nominal operation is measured as 392 W. Its mechanical dimension is 399 x 165 x 249 mm and its net weight is 10.89 kg. It supports chassis mounting and its frame size is categorized as B3.
The 131F6631 drive has integrated RFI class A1/B filters and DC link chokes. It supports motor cable lengths up to 150 m shielded and 300 m unshielded. It is compliant with IEC 61800-9 and SEMI F47 ride-through standards. It is optimized for HVAC systems with functions such as automatic motor adaptation, automatic energy optimization and integrated PID controllers to ensure safe and efficient operation.
Frequently Asked Questions about 131F6631:
Q: Why does the FC-102P15KT4E20H1XGXXXXSXXXXAXBXCXXXXDX drive include both RFI class A1/B filters?
A: The dual RFI class A1/B filters in the 131F6631 help suppress conducted and radiated electromagnetic interference, ensuring compliance with industrial EMC standards. They protect both the drive electronics and nearby sensitive equipment from voltage spikes and noise.
Q: How does the automatic motor adaptation feature benefit operation of the 131F6631?
A: The motor adaptation allows self-tuning of parameters like magnetizing inductance and rotor inertia. This leads to smoother starts, better torque control, and more reliable operation when motors are replaced or load conditions change.
Q: What is the significance of offering selectable carrier frequency between 2 kHz and 16 kHz?
A: In the 131F6631 drive, lower carrier frequencies reduce switching losses, improving efficiency especially under low load. Higher frequencies reduce audible noise and minimize harmonic distortion but increase heat and switching stress.
Q: Why is a displacement power factor > 0.980 important in this Danfoss 131F6631 (FC-102P15KT4E20H1XGXXXXSXXXXAXBXCXXXXDX) drive?
A: A displacement PF above 0.980 means the current and voltage waveforms are nearly in phase, reducing reactive power. It improves utility billing, reduces stress on supply infrastructure, and increases usable capacity.
Q: How does the drive’s scan interval of 5 ms affect control performance?
A: The 5 ms scan interval ensures rapid detection and response to input changes. It enables better regulation of process loops, faster reaction in safety stops and accurate tracking of digital inputs.
