Key issues

Q1: What are the core positioning and differences between the 9300 and ECS servo platforms?

answer:

9300 series: Universal high-power servo, power 0.37-75kW, hardware standardization, configurable functions, suitable for single machine/single axis high-power scenarios.

ECS series: Compact multi axis servo, peak value 4-64A, DC bus power supply, small size, high dynamic performance, suitable for multi axis synchronization, robotics, and embedded installation.

Q2: What are the safety functions and core protection indicators of Lenze servo system?

answer:

Standard Safe Standstill, meeting EN 954-1 Category 3.

Protection level: IP20 (standard), penetrating installation heat sink IP41, optional IP54.

Electrical safety: Full protection against overvoltage/undervoltage/short circuit/grounding/overload/overheating.

Q3: How to select the bus capacitor for ECS servo system? What is the judgment formula?

answer:

Formula: k=C/P (C=total bus capacity μ F; P=average power of the total shaft in kW.

Judgment: k ≥ 100 μ F/kW does not require a capacitor module; If k<100, an ECS-K capacitor module (705/1410 μ F) needs to be added.
