---

### **Cons**

1. **High Initial Cost**

- Servo motors like the **MWA21A 1755** are **more expensive** than standard AC or DC motors due to their **precision engineering, rare-earth magnets, and integrated drive compatibility**.

- The **full system cost** (motor drive wiring integration) can be significantly higher than alternatives.

2. **Complex Installation and Setup**

- Requires **specialized knowledge** for proper wiring, parameterization, and integration with control systems.

- **Mismatched sizing** (e.g., selecting a motor with excessive torque) can lead to **inefficient operation or mechanical stress**.

- **Commissioning time** is longer compared to plug-and-play solutions like standard AC motors.
