Frequently Asked Questions (FAQ)

What does "variable torque" mean for this drive?

It means the drive's control algorithm is optimized for applications where the required torque increases with the square of the speed, such as centrifugal pumps and fans. This optimization maximizes energy savings.

Can this drive be used for constant torque applications like conveyors?

While it may run constant torque loads at reduced capacity, it is specifically optimized for variable torque. For heavy constant torque applications, a drive rated for constant torque is recommended.

How do I access the stored fault history?

The fault history can be viewed and cleared through the built-in operator panel interface or via the RS485 communication port using configuration software.

Is a braking resistor required?

For typical fan and pump (variable torque) applications, a braking resistor is usually not required as the load does not normally cause regenerative braking.

What is required for proper installation?

Installation requires a suitable protective enclosure, correct three-phase 460V power, appropriately sized input fuses or circuit breakers, and proper grounding. Always follow the official installation manual.
