FC-051P2K2T4E20H3BXCXXXSXXX (Order No.132F0022｜Frame M2, 2.2 kW, 380 V) Full List of Compatible Accessories
The drive is delivered without control panel, brake resistor and door-mount kit. Below are original manufacturer compatible models sorted by application:
- Local Control Panels (Essential for Commissioning)
| Order No. | Model | Description |
| 132B0100 | LCP11 | Digital control panel, without potentiometer, IP54 rated panel, for basic parameter setting and parameter copying |
| 132B0101 | LCP12 | Digital control panel with integrated potentiometer, supports local speed adjustment, preferred for on-site commissioning |
⚠️ Code X in model designation = panel excluded; panel must be purchased separately.
- Remote Door-Mount Kits for Control Panels
| Order No. | Specification | Purpose |
| 132B0112 | 1.5 m cable door mounting kit | Mount LCP11/LCP12 on control cabinet door |
| 132B0102 | 3 m cable door mounting kit | Long-distance cabinet door installation, including sealing assembly |
III. Protection & Mounting Upgrade Kits (For M2 Frame Only)
| Order No. | Name | Function |
| 132B0109 | IP21 Protection Kit for M2 | Original unit IP20; protection class upgraded to IP21 (NEMA Type1) after installation |
| 132B0106 | De-coupling partition kit M1/M2 | Improve heat dissipation and reduce electromagnetic interference for multi-drive side-by-side installation |
DIN rail mounting kit is only available for M1 frame. M2 frame does NOT support DIN rail mounting.
- Braking System (Code B = Built-in Brake Chopper)
Recommended Brake Resistor Specifications (Danfoss Official Specification)
Minimum resistance value: 90 Ω
Recommended power rating: ≥200 W (normal start-stop); select 400 W for frequent braking
Danfoss does not provide standard brake resistors with dedicated order numbers. Source externally according to 90 Ω / ≥200 W specification. Increase power rating for heavy-duty cycles.
- Commissioning & Communication Accessories
- PC commissioning cable
FC51 has onboard RS485 terminals. Use USB-to-RS485 adapter together with free MCT10 commissioning software (available for download on official website; Order No.130B1000 refers to software CD media).
- Fieldbus Expansion Note
FC51 has no slots for optional communication cards. Only native Modbus RTU over RS485 is supported; Profibus, EtherNet/IP and other fieldbuses cannot be added.
- Optional Filter & Reactors
This unit is equipped with built-in H3 = Class A1/B RFI filter (Category C1)
No extra input EMC filter required for standard cabinet installation;
For long motor cables or high-interference sites: install external 3-phase input AC line reactor (6 A reactor matched for 2.2 kW, 400 V system)
Use shielded motor cables; recommended maximum cable length ≤15 m when built-in filter is enabled.
VII. Spare Parts (M2 Frame)
132B0127｜FC51 M2 Frame spare parts pack (terminal cover, RS485 connector, earthing screws)
VIII. Matching Drive Motor (Standard Selection)
3-phase asynchronous motor 2.2 kW, 380 V; rated current ≈4.8~5.2 A, compatible with drive rated output current 5.3 A
- Next-Generation Alternative Inverter (FC51 End-of-Life Backup)
iC2-Micro 2.2 kW 3-phase 400 V. Highly compatible terminal definitions and installation dimensions, applicable as replacement for new projects.
Quick Selection Guidelines
- Single unit on-site commissioning: LCP12 (132B0101) recommended;
- Cabinet door operation required: select 132B0112 (1.5 m) / 132B0102 (3 m);
- Frequent start-stop and rapid braking: externally source 90 Ω ≥200 W brake resistor;
- Multiple drives installed side-by-side: equip M2 de-coupling partition kit 132B0106.
