Frequently Asked Questions (FAQ) – Arkel ADrive 4C220

Q1: What is the power capacity of the ADrive 4C220?
A: This inverter is designed for high-demand applications using elevator motors rated up to 22 kW (approximately 30 HP).

Q2: Is the ENCABIT-Plus module required for synchronous (gearless) motors with this drive?
A: Yes, the Arkel ENCABIT-Plus module is necessary to interface the required absolute encoders (EnDat, SSI, SinCos) for closed-loop control of synchronous motors.

Q3: Can it operate a standard induction motor?
A: Yes, the ADrive 4C220 supports both closed-loop vector control (with an incremental encoder) and open-loop V/F control (no encoder needed) for asynchronous (induction) motors.

Q4: What are the main differences compared to the ADrive 4C150?
A: The ADrive 4C220 offers a higher power rating (22kW vs 15kW) and nominal current (50A vs 35A). Both models share the same Size-C physical housing and core functionalities.

Q5: Does this drive include a braking resistor?
A: No. A braking resistor, appropriately sized for the high power and potential energy regeneration of a 22kW system, must be selected based on the elevator’s specifications and purchased separately. Refer to Arkel documentation for guidance.

Q6: How does this drive handle power outages?
A: It supports emergency evacuation mode when correctly integrated with an external 24VDC power supply for its control circuits and a suitable high-capacity battery pack or UPS connected to its main power input terminals (L1/L3).
