Product Description:

The 137H1044 is a variable frequency drive manufactured by Danfoss as part of the VLT FC 302 Automation Drives series. Installed in a control cabinet, the unit converts fixed line power into a variable output so industrial motors can match process demands for speed, acceleration, and torque. The 302 designation places it in the FC 302 range, which is intended for automation duties that require adjustable motor control. This type of drive is used where motor speed must change with process demand instead of running at a fixed line frequency.

The drive handles a mechanical load of 15 HP and has an electrical power rating of 11 kW. It accepts 380–500 VAC from a three-phase power supply, which suits common industrial distribution systems. The housing has an IP20 / chassis rating, so the unit is finger-safe but still requires installation inside an enclosure. A coated printed circuit board helps resist airborne contaminants. Standard cable entry points support organized routing inside enclosed panels. The unit is supplied without a local control panel, so keypad access must be added externally when needed.

Option slots support networked motion control and feedback-based operation. The A slot carries EtherCAT MCA 124 for real-time fieldbus communication, while the B slot uses the MCB-103 resolver option to process resolver feedback for closed-loop control. A built-in brake chopper dissipates braking energy, and an integrated RFI filter helps reduce conducted emissions. This arrangement supports motion applications that need both network communication and direct motor feedback without separate external modules. No B-slot adaptation is loaded, and the C0, C1, and D option positions are empty. Software options are not installed, so parameter access is handled through the fieldbus connection or an external keypad.
