Arkel ENCI Incremental Encoder Interface Card for ARCODE

The Arkel ENCI is a specialized high-speed interface module designed exclusively for the ARCODE Integrated Lift Control System. It acts as the precision bridge between the elevator machine and the controller, processing differential signals from Incremental Encoders. This card is essential for closed-loop control of asynchronous (geared) motors, providing real-time data on cabin speed, direction, and position to ensure millimetric floor leveling and superior ride comfort.

Technical Specifications: Arkel ENCI

Product Description

The Arkel ENCI (1002920) is a critical component for modernizing geared traction elevators or installing new asynchronous systems with the ARCODE controller. While synchronous motors use absolute encoders, asynchronous (induction) motors rely on incremental encoders to achieve “closed-loop” performance. The ENCI card processes these signals to eliminate the “creeping” often associated with older geared lifts.

High-Performance Positioning: The ENCI card reads dual-channel pulses (A and B) to determine direction and distance. By utilizing the Z-channel (Index pulse), it establishes a precise reference point within the shaft, allowing the elevator to “learn” the floor levels with extreme accuracy. This data allows the ARCODE to modulate the voltage and frequency sent to the motor, ensuring smooth acceleration and imperceptible stops.

Robust B2B Engineering: In industrial environments, electrical noise can corrupt data. The ENCI utilizes differential signaling (reading both the signal and its inverse), which filters out electromagnetic interference from power cables. This ensures that the position data remains reliable even over long travel heights or in noisy machine rooms.

Frequently Asked Questions

Q1: What is the difference between the ENCI and ENCA cards?

The ENCI is designed for Incremental Encoders, which are typically used with Asynchronous (Geared) motors. The ENCA card is designed for Absolute Encoders (EnDat, SSI, SinCos), which are required for Synchronous (Gearless) motors. You must select the card that matches your motor’s encoder type,.

Q2: Does the ENCI card support HTL and TTL encoders?

Yes. The ENCI card interface, when paired with the ARCODE main unit, supports standard incremental encoder voltages (typically 5V TTL or 10-30V HTL). Ensure the encoder resolution (pulses per revolution) is correctly entered in the ARCODE parameters,.

Q3: Why is the “Z” channel connection important for this card?

Incremental encoders lose their position data when power is cut. The Z channel (or Index channel) provides a physical reference signal once per revolution. This allows the system to verify its position and perform a “homing” run to reset the floor counter if the system is reset or power is lost,.

Q4: Can I use this card with the ARL-500 controller?

No. The ENCI (1002920) is specifically manufactured as a peripheral module for the ARCODE Integrated Control Unit. The ARL-500 uses a different method or onboard inputs for encoder connections depending on the specific configuration,.
