Frequently Asked Questions (FAQ)

1. What is the difference between input and output current on the Lenze ECSEE020C4B?
Input current is 15.9A AC, while output current is 20A DC. The drive converts AC to DC for servo motor control.

2. Can I use the Lenze ECSEE020C4B with a single-phase power supply?
No, this model requires a 3-phase input. Using single-phase will cause underperformance or damage.

3. Does the Lenze ECSEE020C4B include a built-in brake chopper?
Yes, it includes an integrated brake chopper for dynamic deceleration. External braking resistors are optional.

4. What happens if the input voltage drops below 180 VAC?
The drive will trigger an under-voltage fault and stop the motor. Provide stable 3-phase power for safe operation.

5. Is the Lenze ECSEE020C4B compatible with third-party servo motors?
It works best with Lenze servos. Third-party motors may require parameter tuning and compatible feedback interfaces.
