• Rated power (LO): 1.10 kW / 1.50 hp
• Rated power (HO): 0.75 kW / 1.00 hp
• Output current: 3.10 A (LO), 2.20 A (HO), 3.20 A (IN)
• Maximum output current: 4.40 A
• Pulse frequency: 4 kHz
• Output frequency: 0-240 Hz (vector), 0-550 Hz (V/f)
• Overload capability: 150% for 3s (LO), 200% for 3s (HO)
• Efficiency: 0.97
• Power loss: 48.1 W

These specifications highlight the drive's ability to handle both standard and high-overload conditions, ensuring reliable operation even in demanding environments.

Applications and Use Cases

This Siemens drive is suitable for a variety of applications, including conveyors, pumps, fans, and machine tools. For example, in a packaging line, the drive can maintain consistent speed despite load variations, improving product quality and reducing downtime.

Installation and Setup

Proper installation is critical for optimal performance. The drive is designed for air cooling with an integrated fan, requiring a cooling air flow of 0.005 m³/s. It should be mounted in a location that allows adequate airflow and maintains an ambient temperature of -10 to 40 °C during operation. The unit has plug-in screw terminals for line, motor, and DC link connections, with conductor cross-sections ranging from 1.00 to 2.50 mm² (AWG 18-14). The maximum motor cable length is 150 m (shielded or unshielded).

Maintenance and Reliability

Regular inspection of the drive is recommended to ensure long-term reliability. Check the cooling fan for dust accumulation and verify that the ambient temperature stays within specified limits. The drive's IP20 protection (UL open type) allows for safe installation in most industrial enclosures. With a net weight of 1.40 kg and compact dimensions (73 mm width, 173 mm height, 160 mm depth), it fits easily into control panels.

Communication and Integration

The 6SL3210-1KE13-2UF2 supports PROFINET and EtherNet/IP, enabling seamless integration into modern industrial networks. This allows for remote monitoring and control, which is essential for optimizing production processes. The drive also includes six standard digital inputs, one fail-safe digital input, and one digital output (relay changeover), providing flexible I/O options.

Compatibility and Standards

The 6SL3210-1KE13-2UF2 complies with UL, cUL, CE, and C-Tick (RCM) standards, ensuring it meets international safety and EMC requirements. It also carries CE marking for EMC and Low Voltage Directives. The drive is designed to meet efficiency class IE2, contributing to energy savings.

Common Issues and Troubleshooting

One common issue with VFDs is overheating due to inadequate ventilation. Ensure the cooling fan is operational and the air intake is not blocked. Another issue is incorrect wiring, which can cause fault codes. Always follow the wiring diagram provided in the manual. If communication errors occur, verify the PROFINET or EtherNet/IP settings and cable connections.
