---
#### **Cons**
1. **High Initial Cost**
The 1336 series is a premium product, and the **1336S-BRF20-AN-EN5 model** (rated for **20 HP / 15 kW**) is priced higher than basic or generic VFDs. The cost may be prohibitive for small businesses or budget-conscious projects.
2. **Complexity for Non-Experts**
- The advanced features (e.g., PID control, regenerative braking, multi-protocol communication) require **technical expertise** to configure and troubleshoot.
- Programming and setup may necessitate training or hiring an automation specialist, increasing operational costs.
3. **Size and Installation Requirements**
- The 1336 series is a **rack-mounted or NEMA 12/4X enclosure** unit, requiring dedicated space in control panels or electrical rooms.
- Installation may require **additional wiring, grounding, and cooling considerations**, especially in high-ambient-temperature environments.
4. **Limited Overload Capacity**
While the 1336 series is robust, it has **standard overload ratings** (e.g., 115% continuous load for 1 hour). Continuous heavy overloads may reduce lifespan or require derating.
5. **Depreciation and Obsolescence Risk**
- Like all industrial equipment, VFDs may become **obsolete over time** as newer models with improved features (e.g., AI-driven diagnostics, IoT connectivity) are released.
- Rockwell Automation occasionally phases out older models, which could affect long-term spare parts availability.
6. **Potential for Overkill in Simple Applications**
If the application only requires **basic speed control** (e.g., a small fan or pump with no advanced requirements), a **lower-cost VFD** (e.g., a basic Schneider or Siemens model) may suffice without justifying the 1336 series premium features.
7. **Regulatory and Compliance Considerations**
- In some regions, **harmonic mitigation** (e.g., using reactors or filters) may be required to comply with electrical grid codes when using VFDs.
- Proper **grounding, shielding, and EMI suppression** may be needed to avoid interference with other equipment.
