Professional FAQ

• What types of machinery typically use a 7.5 kW drive like this?

This drive is suitable for medium-to-high power applications such as centrifugal pumps, large conveyors, mixers, fans, and the main axis drives of medium-sized machine tools or industrial robots.

• How do the programmable digital and analog I/O enhance functionality?

The 8 digital inputs can be configured for functions like start/stop, jog, or fault reset. The 2 analog outputs can be programmed to provide a real-time signal proportional to motor speed, torque, or power, useful for PLC monitoring or chart recording.

• What is the practical benefit of the high 35.6A maximum current?

This allows the 14F5C1D-380A to deliver up to 200% or more of its rated torque for short periods. This is essential for overcoming breakaway friction, accelerating high-inertia loads quickly, or handling momentary process overloads without faulting.

• Why is earth fault monitoring a critical safety feature?

It detects leakage current to ground, which can indicate insulation breakdown in the motor or cabling. Early detection helps prevent electrical shock hazards, equipment damage, and unexpected downtime by alerting operators to the condition.

• Can this drive control a standard 400V 4-pole motor (approx. 1500 RPM)?

Yes, it is ideally suited for that. By setting the output frequency to 50 Hz, it will provide the motor's rated speed. The 0-800 Hz range also allows you to run the same motor at higher speeds (if mechanically feasible) or control 2-pole motors (approx. 3000 RPM at 50 Hz).
