Lenze 00455 JK-IMP3 V0.1 Pulse / Encoder Interface Card
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00455 JK-IMP3 V0.1 is a specialized pulse and encoder interface card developed within the JK Sub-Module Series for legacy Lenze frequency inverters. Operating as an internal option card, this module enables host inverters to receive and process 24 V DC HTL impulse and speed feedback signals from incremental encoders and pulse generators. The card features an internal multi-pin backplane edge connector that mounts directly into the option slot of the host drive control board, delivering reliable speed monitoring for continuous web processing, material handling, packaging machinery, and conveying systems.
Connecting field signals to the module is accomplished through onboard screw or plug-in terminal strips, providing clean signal separation for pulse tracks, ground, and supply lines. Commissioning a replacement unit requires fitting the physical module securely into the host drive option slot and verifying terminal block wiring. Parameterization and operational setups are managed through Lenze Global Drive Control (GDC) software or directly via the inverter keypad. Because key parameters are automatically retained in the host inverter non-volatile EEPROM memory, replacing a damaged card is straightforward, though ABC Industrial Parts can assist with parameter verification and commissioning support.
System status and signal monitoring are handled directly through the host inverter operator keypad, GDC software diagnostics, or fault indication displays that alert operators to pulse loss or speed feedback failure conditions. First-line troubleshooting involves checking the physical seating of the card edge connector, verifying terminal connections from the field encoder, and checking 24 V DC signal levels. Physical failures within the interface circuitry cannot be serviced in the field; replacing the sub-module or utilizing tested exchange units from ABC Industrial Parts offers a fast path to restoring machine uptime.

Programming and Configuration
Configuration of the Lenze 00455 JK-IMP3 V0.1 interface sub-module is conducted through Lenze Global Drive Control (GDC) software or the host inverter integrated keypad display. The module operates in full alignment with the host drive architecture, allowing maintenance technicians to inspect and modify feedback settings directly.
All configuration parameters defined during setup are stored in the host inverter non-volatile EEPROM memory. This centralized storage structure protects drive settings against power loss and simplifies module replacement, as the new card immediately utilizes the existing parameter set stored within the host inverter.
Communication and System Integration
The Lenze 00455 JK-IMP3 V0.1 interfaces with the host drive via a multi-pin card edge backplane connector designed specifically for legacy Lenze frequency inverters equipped with JK option slots. This internal connection provides direct communication between the option card and the primary drive control board without taking up external control panel space.
External field devices, such as 24 V DC HTL impulse generators and incremental encoders, connect directly to the module via screw or plug-in terminal strips. The terminal interface accommodates dedicated wiring channels for pulse inputs, power supply, and ground reference.
Diagnostics and Status Indication
Diagnostic monitoring for the Lenze 00455 JK-IMP3 V0.1 relies on the host inverter internal diagnostic features. Fault conditions such as pulse loss or speed feedback errors trigger alarm notifications displayed on the inverter operator keypad display or recorded in Lenze Global Drive Control (GDC) software.
Technicians can monitor live speed feedback signals and verify pulse inputs through the GDC software interface during active drive operation, allowing rapid detection of signal loss or wiring issues.
Replacement and Spare Part Considerations
When replacing a Lenze 00455 JK-IMP3 V0.1 module, main power to the inverter must be completely isolated prior to opening the drive enclosure. The existing card is removed from its internal JK option slot, allowing the replacement board to be inserted into the multi-pin backplane connector.
Since operating parameters reside in the non-volatile EEPROM memory of the host inverter, swapping the hardware does not require re-entering configuration data in standard installations. Technicians need only secure the card, re-attach the plug-in terminal strips, and verify signal integrity using the host keypad or GDC software.
Frequently Asked Questions
What is the primary function of the Lenze 00455 JK-IMP3 V0.1 card?
The Lenze 00455 JK-IMP3 V0.1 is an option card that processes 24 V DC HTL impulse generator and encoder feedback signals for legacy Lenze frequency inverters, enabling closed-loop speed monitoring and motor control.
How is the Lenze 00455 installed inside the host inverter?
