Frequently Asked Questions

What does the “NBSQ” connectivity designation represent on the AKD-B02406?

NB” designates standard base drive configuration without extended auxiliary I/O cards. “SQ” denotes factory hardware configuration for SynqNet® motion bus communication via dual dedicated RJ45 interface ports (X5 and X6).

Can the AKD-B02406-NBSQ-0000 be operated on a single-phase mains supply?

No. Unlike smaller 3A, 6A, and 12A AKD 120/240V drives that permit single-phase power, the 24A current frame (AKD-x02406) strictly requires a balanced 3-phase AC input supply (120/240 VAC line-to-line) across terminals L1, L2, and L3 to sustain internal DC-link bus ripple requirements under load.

How do I commission the drive without a SynqNet master connected?

Initial axis setup, motor pairing, feedback calibration, and open-loop testing are performed via the independent TCP/IP Ethernet service port (X35 or Service RJ45) using a Windows PC running Kollmorgen WorkBench software. The service port operates over standard IP networking and does not interfere with the SynqNet real-time network.

What is the maximum recommended motor cable length for this drive?

The standard maximum motor power and feedback cable distance is 50 meters (164 feet) when using Kollmorgen pre-fabricated, low-capacitance shielded cables. Exceeding this length requires output motor chokes (dV/dt filters) to prevent premature motor winding dielectric failure and nuisance overcurrent trips (Fault F201).

What should I do if the drive displays fault F106 (Over-temperature power stage)?

Fault F106 indicates heat sink temperature has exceeded the thermal threshold of 85°C. Verify that the cabinet internal temperature remains under 40°C, inspect the integrated heatsink fan for rotation and dust blockage, ensure minimum mounting clearances (100 mm top and bottom clearance for natural convection airflow), and verify that the drive switching frequency has not been elevated above 8 kHz without appropriate current derating.
