Lenze 00393112 EMB9352-E AS-Interface Communication Module

Configuration of the Lenze 00393112 EMB9352-E module focuses primarily on setting the AS-Interface station address within the valid node range of 1 to 31. Initial addressing can be performed offline using a standard handheld AS-i addressing device connected to the network terminals, or online through automatic station assignment from an AS-Interface master complying with specification 2.1. Unconfigured replacement modules default to address 0, which triggers a diagnostic warning until a valid node address is programmed.

All addressing data is written to non-volatile EEPROM memory built into the EMB9352-E function module. This internal memory preserves node parameters permanently without requiring battery backup or continuous auxiliary power. System engineers can monitor communication parameters and drive parameter sets using Lenze Global Drive Control (GDC) software connected to the host 8200 vector or 9300 series drive controller.

The EMB9352-E acts as an AS-Interface slave interface adhering strictly to AS-Interface specification version 2.1. It supports network communication rates up to 167 kbit/s across two-wire AS-i ribbon cable or standard round cable networks. Physical connection to the fieldbus line is made through a 2-pole plug-in screw terminal block, allowing simple module disconnects during maintenance without disrupting the main fieldbus line.

Interfacing with the host drive is accomplished through a multi-pin header plug-in connector designed specifically for the dedicated Function Interface (FIF) slot of Lenze 8200 vector frequency inverters and 9300 series servo and vector drive controllers. The module receives its operational power directly from the AS-Interface line, functioning within an operating voltage range of 26.5 V DC to 31.6 V DC without requiring an external auxiliary power supply.

Status diagnostics for the Lenze 00393112 EMB9352-E module are observed directly through the front multi-color AS-i LED indicator. System technicians can determine network status and hardware operational states at a glance during routine maintenance or fieldbus troubleshooting.

Complementary diagnostic data, including drive-level response and trip codes, can be accessed using a Lenze XT keypad or through Lenze Global Drive Control (GDC) engineering software connected to the drive host.

Status LED Indicators

When swapping a failed Lenze 00393112 EMB9352-E communication module, verify that the replacement unit shares the exact model designation EMB9352-E and part number 00393112 to ensure electrical and physical compatibility with the host Lenze drive. The module is fully compatible across Lenze 8200 vector inverters as well as Lenze 9300 series servo and vector drive controllers equipped with a Function Interface (FIF) slot.

Before putting a spare module into production, the station address must be matched to the address assigned in the master PLC or AS-Interface fieldbus configuration. Because node addresses are stored in the module's internal EEPROM, a replacement unit taken directly from storage must be addressed using a handheld tool or programmed via the master before normal communication can be established. Additionally, verify that the AS-i line voltage supplied across the 2-pole screw terminal stays within the specified 26.5 to 31.6 V DC range.
