Designed to manage DC bus power distribution and regenerative braking energy within multi-axis drive systems, the Lenze EMB9352-E serves as a dedicated power supply and brake chopper module for the 9300-Series vector control range. This module provides a centralized DC link supply for multiple servo inverters while safely dissipating regenerative energy generated during rapid deceleration phases, protecting the entire drive lineup from overvoltage faults.

Key Features

Integrated high-capacity brake chopper to handle dynamic deceleration cycles.
Direct DC bus connection terminals for efficient energy sharing between multi-axis drives.
Compact bookstyle housing designed for space-optimized control cabinet installation.
Dedicated thermal monitoring loop to prevent external brake resistor overheating.
Seamless integration with Lenze 9300-Series servo controllers and vector inverters.

Applications

Multi-axis packaging machinery and high-speed wrapping systems.
Material handling gantries, hoists, and automated storage retrieval systems (ASRS).
Continuous printing presses and paper processing machinery.
Automated assembly lines requiring coordinated deceleration of high-inertia loads.

Alternative Models & Compatibility

The EMB9352-E is fully compatible with Lenze 9300-Series EVF93xx and EVS93xx servo controllers. When replacing older revisions of this module, ensure that the DC bus voltage thresholds configured in your main drive parameters match the hardware specifications of the replacement unit to prevent premature chopper activation.

Application Pitfalls & Engineering Notes

To prevent thermal pooling inside the control cabinet, maintain a minimum vertical clearance of 100 mm above and below the module. If the external braking resistor is undersized or lacks sufficient ventilation, the chopper module may experience thermal stress, leading to a permanent open-circuit fault on the DC bus.

Commissioning & Wiring Tips

Always use shielded, low-capacitance cables for the connection between the EMB9352-E and the external braking resistor. Ground the cable shield on both ends using low-impedance EMC shield clamps to prevent high-frequency switching noise from corrupting nearby encoder or fieldbus communication lines.

Installation Guidelines

CRITICAL WARNING: HIGH VOLTAGE RISK

Isolate all AC mains power sources before working on the DC bus link. Residual charge in the DC bus capacitors can remain at lethal levels (above 50V DC) for up to 5 minutes after power-off. Always measure the voltage between the +UG and -UG terminals with a calibrated digital multimeter before initiating physical service.

Mount the module vertically on a flat, conductive, and grounded mounting plate inside the enclosure to ensure optimal heat dissipation and EMC grounding.

Connect the DC bus terminals (+UG and -UG) to the adjacent servo inverters using the shortest possible busbars or twisted copper conductors.

Wire the external braking resistor to terminals Rb1 and Rb2. Ensure the thermal overload contact of the resistor is wired directly into the T1/T2 monitoring loop to trigger a system-wide shutdown in case of resistor overheating.

What is the primary function of the Lenze EMB9352-E?

It serves as a DC bus power supply and brake chopper module, distributing power to multi-axis 9300-Series servo systems and safely dissipating regenerative braking energy through an external resistor.

Can this module be used with other Lenze drive series?

It is specifically designed for the 9300-Series vector and servo controllers. Cross-series integration requires verifying DC bus voltage compatibility and physical mounting constraints.

How does the module handle thermal overload?

It features dedicated terminals (T1/T2) to monitor the thermal contact of the external braking resistor, allowing the control system to trip the main supply before thermal runaway occurs.
