Introduction: Servo and mechanical drive selection for the L800 carton erecting machine begins with the production rhythm a packaging plant actually runs, because the L800-A and L800-C share a single lane platform but use different motion systems for different changeover and box-complexity profiles.
DWELLPAC builds the L800 as a single lane carton erecting machine for pre-cut paperboard and micro corrugated blanks. The L800-A uses a servo drive with an 8 kW system; the L800-C uses a mechanical drive with a 5 kW system. Both are rated at a nominal maximum of 200 pcs/min, both run on 380V/50Hz and 0.6 MPa clean dry air, and both carry CE certification. The practical decision is whether the production mix needs servo flexibility or mechanical repeatability.
Changeover frequency is the first question because it shows whether the line needs flexible motion or repeatable mechanical cycles. A plant that runs the same box for days can absorb a slower, simpler changeover. A plant that switches cartons several times a shift feels every minute of setup. With a servo drive, the motion profile is adjusted through the control system rather than rebuilt through mechanical linkages. That matters when the next job has a different blank size, side flap height, or conicity. The L800-A is the servo configuration to compare first when format changes are normal. The mechanical L800-C is the focused option: its 5 kW mechanical system suits stable long runs, where the same carton runs for hours or days and simple, economical operation matters. In that setting, changeover frequency is low, so the extra flexibility of a servo system may not pay back. Count how many times your line changes box formats in a week. Once or twice points toward a mechanical drive. Several times a shift puts servo control at the top of the list.
In daily production, the difference appears in three places: how quickly the line recovers after a format change, how consistently it handles complex folds, and how much power it draws. Both models share the same single lane layout and the same 200 pcs/min nominal maximum, so the comparison comes down to how each drive behaves across a real production day.
The L800-A uses a servo drive and an 8 kW system. Servo motion provides programmable positioning, so format changes can be handled with greater precision and less mechanical adjustment. That benefits plants running mixed orders, short campaigns, or frequent size changes. The L800-A is also built for 8 corner boxes, which require tighter control of the folding sequence. Servo drive supports vertical motor placement, which helps save floor space around the erecting station. The practical result is a machine that can be retuned for a new job without changing the mechanical core of the line. It can cover more SKUs and reduce the need for a second dedicated line.
The L800-C uses a mechanical drive and a 5 kW system. Its strength is stable, repetitive production. When one carton style runs for a long stretch, the mechanical linkage delivers the same cycle again and again, and the lower power draw supports economical daily operation. This configuration fits packaging plants with long orders and a preference for a straightforward machine with fewer electronic variables. Mechanical drive also gives maintenance teams a familiar system, with fewer software parameters to manage during normal production. The trade-off is flexibility: complex box styles and frequent format changes belong on the servo model. For a single-box line, the mechanical L800-C often offers the cleaner cost-per-carton case.
A useful drive recommendation depends on two sets of data: what you produce and what your plant can supply. Share the number of box formats you run, how often you change them, the most complex style in the mix, and your target output per shift. Include the board range. The L800 handles 150–400 gsm board and micro corrugated board up to 1.5 mm, so your actual board grade helps confirm that the machine matches the job. If you know your blank sizes and conicity range, include those too; they show how much adjustment the line will need. On the electrical side, start with the supply. Both L800 models run on 380V/50Hz and need 0.6 MPa clean dry air. Then compare the load: L800-A is rated at 8 kW, while L800-C is rated at 5 kW. That difference matters when planning a new line, adding a machine to an existing panel, or comparing electrical conditions for a quote. NIST guidance on industrial control systems treats the control architecture as part of the production task, so tell the supplier whether the machine will run stand-alone or connect to a larger line. IEC electrical installation references also support planning wiring and supply around the actual machine load. For the inquiry, send a simple production profile: box types, changeover frequency, board grade, blank size, target speed, and available power and air supply—the same data pulp molding machine manufacturers need for adjacent fiber-forming projects. Ask the supplier to confirm whether the servo L800-A or mechanical L800-C fits that profile. Servo brand, PLC brand, glue system, price, lead time, and warranty are not published; ask the supplier to confirm them.
Drive selection on the L800 comes down to production rhythm. Frequent format changes, mixed SKUs, and 8 corner boxes point to the L800-A servo drive with its 8 kW system. Stable long runs of one carton style point to the L800-C mechanical drive with its economical 5 kW system. Both share a single lane layout, a 200 pcs/min nominal maximum, 380V/50Hz power, 0.6 MPa clean dry air, and CE certification. Share your box mix, changeover frequency, target output, and electrical supply, then ask for a confirmed drive recommendation and the commercial details you need.
A：Start with changeover frequency and box complexity. If your line switches formats often, runs mixed orders, or produces 8 corner boxes, the L800-A servo drive is the natural fit; its 8 kW system supports precise, repeatable changeovers. If your line runs one box style for long stretches, the L800-C mechanical drive is the economical choice with its 5 kW system. Both models share a 200 pcs/min nominal maximum, so the decision is about flexibility versus stable repetitive production.
A：The L800-C is designed for stable long runs and economical operation. Complex box styles and 8 corner boxes are better matched to the L800-A servo model, which is built for tighter folding control and frequent format changes. If your production plan includes 8 corner boxes, compare the L800-A first. The L800-C remains a strong option when the carton style is simple and the order volume stays steady.
A：Both L800 models need 380V/50Hz power and 0.6 MPa clean dry air. The load differs: L800-A uses an 8 kW servo system, while L800-C uses a 5 kW mechanical system. Share your available panel capacity and air supply details during the inquiry so the recommended configuration matches your plant conditions.
