Replacement & Compatibility FAQ
Q: Can I replace 6SL3210-1KE18-8UP1 with 6SL3210-1KE18-8AF1?
A: The AF1 suffix denotes a chassis (floor-standing) format. It is electrically equivalent but physically incompatible with a Booksize cabinet — do not substitute without verifying mechanical fit.
Q: Is the 6SL3210-1KE18-8UP1 compatible with older S120 firmware?
A: Firmware version must match the Control Unit. Units shipped by Konmask.com include the firmware version on the label; contact us if a specific version is required.
Q: Can this module run in single-axis or multi-axis configurations?
A: Yes. It supports both single-axis (standalone) and multi-axis (shared DC bus) configurations within the S120 Booksize system.
Q: What is the lead time for out-of-stock units?
A: Typical lead time is 3–10 business days for standard stock; 4–8 weeks for factory-new orders. Contact us for current availability.
