Operating Parameters:

The optimal operating temperature range for the device is between -10°C to +50°C. For non-operational storage and transport, you have permission to store it at a maximum of 70 degrees.

Vibration resistance is an essential aspect of the 6SE6420-2AD23-0BA1's operating parameters. It can resist vibrations within a frequency range of 10 Hz to 58 Hz (constant amplitude) with an amplitude of 0.075 mm (peak value), compliant with IEC 60068-2-6 standards. During transportation, it can withstand vibrations within a frequency range of 10 Hz to 150 Hz (constant amplitude) with an amplitude of 2 g (peak value), ensuring its resiliency during transit.

Concerning shock resistance, the 6SE6420-2AD23-0BA1 drive is designed to withstand shocks per IEC 60068-2-27 standards. It can withstand shocks with a duration of 11 ms and half-sine acceleration of 15 g, evidencing its ability to withstand sudden impacts without compromising performance.

Installation and Wiring:

For safe and optimal performance, only qualified personnel should handle the installation of the 6SE6420-2AD23-0BA1. The device must be mounted on a flat, non-flammable, and vibration-free surface, with at least 100mm clearance space above and below for proper ventilation.

Wiring should conform to local and national electrical codes. Clear and well-labeled connection points are provided for the power supply, motor, and control terminals. Use a shielded motor cable to minimize electromagnetic interference. The earth connection must be secure, and all wiring should be inspected thoroughly before powering up the system.

Built-in Safety and Prevention

The 6SE6420-2AD23-0BA1 frequency converter is a cutting-edge technology boasting superior energy efficiency, reliability, and operational versatility. This unit is well-equipped with a range of safety and prevention measures, including motor short-circuit protection, overload and underload voltage protection, input/output phase loss protection, over-temperature protection, and adjustable motor thermal protection to protect the motor against overheating.

Additionally, it comes with an automatic restart feature that guarantees seamless operation in the event of power failure. The ramp-function down and quick-stop functions are in place to avert sudden changes in operation, thereby protecting the system from mechanical stress.
