What makes the 2.2 kW AB0 the most balanced G115D configuration for general conveyor duty?

The 2.2 kW AB0 sits at the intersection of three practical design constraints for conveyor drives: (1) power rating — 2.2 kW covers the largest segment of horizontal conveyor applications, from roller beds and belt conveyors to accumulation zones and transfer cars; (2) EMC compliance — the integrated C2 filter satisfies the most common industrial EMC requirement without external components, yet the AB0 costs less than the AF0 because it omits PROFIsafe hardware the majority of conveyor applications do not need; and (3) thermal design — at 96 W power loss, the fanless FSB heatsink operates with substantial thermal margin, meaning the drive can handle elevated ambient temperatures and repeated overload cycles without approaching thermal limits. This combination of capability and margin makes the 2.2 kW AB0 the go-to variant when a project specifies one drive configuration for all general-purpose conveyor positions.

How does fanless operation at 2.2 kW compare to fan-cooled operation at 4 kW in the same FSB frame?

The same FSB frame (425x180 mm footprint) serves both the fanless 2.2 kW variant and the fan-cooled 4 kW variant. The 2.2 kW drive dissipates 96 W passively; the 4 kW drive dissipates 173 W and adds a fan consuming approximately 5 W. The 2.2 kW variant is 44% lighter on the thermal budget while using an identical heatsink — this is the engineering reason it can operate fanless with thermal margin. For conveyor OEMs, the practical trade-off is: 2.2 kW means no fan to replace over a 10-15 year conveyor life, while 4 kW means nearly double the mechanical power in the same mounting footprint. When the conveyor's mechanical design allows 2.2 kW per drive position — which it does for the majority of horizontal transport and accumulation sections — the AB0 at this power rating offers the lowest total cost of ownership in the G115D wall-mounted range.

When should you choose the AB0 over the AA0 at 2.2 kW?

The AB0 is the correct choice when any of these are true: (1) the installation is on a public low-voltage network where C2 emission limits per EN 61800-3 apply; (2) the conveyor line includes sensitive adjacent equipment — sensors, vision systems, barcode scanners — that can be affected by conducted EMI from unfiltered drives; (3) the end customer's EMC compliance specification explicitly requires Category C2 at the drive level, regardless of the supply network classification. If none of these apply and the drive is on a dedicated industrial transformer with no sensitive co-located equipment, the AA0 variant provides the same motor control performance at lower cost.

Frequently Asked Questions

Can this drive power a conveyor section that occasionally exceeds 2.2 kW mechanical demand?

Yes, within the overload specification. The drive can deliver 200% of rated current (23.6 A) for 3 seconds and 150% (17.7 A) for 57 seconds per 300-second duty cycle. This handles brief mechanical overloads — a pallet momentarily jamming a merge section, a product stack heavier than the design nominal — without tripping. For sustained loads above 2.2 kW, the 3 kW variant (15.4 A rated) or 4 kW variant (20.4 A rated) should be selected.

Is the integrated C2 filter sufficient for residential or light-industrial environments?

Category C2 per EN 61800-3 applies to industrial low-voltage networks where the supply transformer feeds both the drive installation and other industrial equipment. For residential or light-industrial environments (Category C1), additional external filtering or a different drive series with C1 compliance would be required. The G115D with integrated C2 filter is not rated for C1 environments.
