Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E70ACPSE0604S is a central power supply module designed for the Lenze i700 Cabinet multi-axis drive system. Operating on a three-phase AC mains supply from 342 V AC to 528 V AC at 45 to 65 Hz, this unit provides a regulated 565 V DC output to feed adjacent single-axis and double-axis drive modules. Delivering a continuous DC output current of 60 A and a nominal power rating of 41.5 kW, it utilizes an integrated direct-fit DC busbar bridge system to minimize cabinet space and wiring complexity. To accommodate heavy acceleration and dynamic load pulses in high-density motion control panels, the unit supports a peak output current of 120 A for up to 3 seconds, and includes an integrated brake chopper transistor for connecting an external dynamic braking resistor.
System communication and parameter management are established through dual RJ45 EtherCAT interfaces operating at 100 Mbit/s in a line topology. Engineering and setup are supported using Lenze EASY Starter commissioning software or CODESYS-based Lenze PLC Designer tools, while control electronics require an external 24 V DC auxiliary power source. When exchanging a module in an existing system, the EtherCAT master automatically restores all operating parameters directly to the replacement unit over the network, eliminating the need for manual re-commissioning or external parameter backup tools. Maintenance teams sourcing a spare unit can rely on ABC Industrial Parts to supply reliable replacement hardware to keep downtime to a minimum.
Real-time diagnostic capabilities are accessible via the EtherCAT master online registers, internal non-volatile fault logs, and front-facing LED indicators. The RDY status LED indicates DC bus pre-charge and operational readiness, ERR signals faults and warnings, and L/A IN and L/A OUT display network port link and traffic states. Critical hardware conditions, such as continuous fast red blinking of the ERR LED on startup or unresolvable internal component faults, indicate internal board-level failure that cannot be serviced on-site. In these cases, installing a replacement module or utilizing repair services through ABC Industrial Parts offers a fast path to returning the machine to full production.

Programming and Configuration
Configuration and system engineering for the Lenze E70ACPSE0604S power module are conducted using Lenze EASY Starter software or Lenze PLC Designer for CODESYS-based motion controllers. The module interfaces with the central control platform via EtherCAT, enabling full visibility of system status, operational parameters, and fault logs.
During module replacement, manual parameter transferring is not required when the drive system is managed by an EtherCAT master controller. Upon detection of a replacement E70ACPSE0604S unit on the bus, the EtherCAT master automatically reloads the correct parameter sets to the device over the network, bringing the spare unit into operational status quickly.
Communication and System Integration
The E70ACPSE0604S features dual RJ45 100 Mbit/s Ethernet ports configured for EtherCAT communications. This dual-port architecture enables direct line-topology cabling from the central controller across the adjacent single and double axis drive modules within the i700 multi-axis line-up.
In addition to command and status data, the integrated fieldbus system supports direct DC busbar bridge coupling between the power module and drive axes. This reduces cabinet wiring, prevents layout errors, and maintains consistent high-density spacing within automated production machinery.
Diagnostics and Status Indication
System diagnosis is supported through multi-level indicators and software tools. Real-time condition checking can be executed via the Lenze EASY Starter diagnostic monitor, online registers inside the EtherCAT master controller, or by reading the non-volatile internal fault log stored in the module.
Front panel status LED indicators provide immediate feedback on DC bus pre-charging, operation readiness, active errors or warnings, and EtherCAT port link and activity states.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY | Green - Solid / Flashing / Off | Green = Ready for operation / DC bus charged; Flashing Green = Pre-charge / Booting; Off = No control supply voltage |
| ERR | Red - Solid / Flashing / Off | Red Solid = Active fault present; Red Flashing = Warning condition; Off = No fault active; Continuous fast red blink on power-up = Internal hardware failure |
| L/A IN | Green - Solid / Flashing | Green = EtherCAT Input link established; Flashing Green = Data traffic active |
| L/A OUT | Green - Solid / Flashing | Green = EtherCAT Output link established; Flashing Green = Data traffic active |
Replacement and Spare Part Considerations
When replacing a failed E70ACPSE0604S power module, verify that the incoming 3-phase mains voltage matches the specified operating range of 342 V AC to 528 V AC and that the auxiliary 24 V DC supply delivers between 19.2 V DC and 28.8 V DC under load. Inspect the physical DC busbar connectors for signs of thermal stress, contamination, or wear prior to mounting the spare module.
Because the module utilizes automated parameter restoration via EtherCAT, manual transfer of parameter files is usually unnecessary when managed by a configured EtherCAT master. Ensure that the EtherCAT IN and OUT network cables are attached to the correct RJ45 ports to re-establish line-topology communications without bus interruptions.
