Frequently Asked Questions (FAQ)

What does "Variable Torque" mean for this drive?

It means the drive is optimized for applications where the required torque increases with speed, such as centrifugal pumps and fans, allowing for greater energy efficiency.

Can this drive be used for constant torque applications?

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

What is the advantage of the high-attenuation EMC filter?

It provides superior suppression of electromagnetic noise compared to basic filters, ensuring better compliance with EMC standards and minimizing interference in sensitive environments.

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 this application?

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