AC Tech released their sub-mciro series of drives, including the SCM, SCF and SCL series, over 15 years ago and these drives have had a great run.
But now the time has come for the torch to be passed. AC Tech Lenze has announced that the time has come to focus on their newest products and gradually decrease production of these series by 2019.
What does this mean for you? The bottom line is that we have until April 2017 to place our orders for drives in these series.
Lenze AC Tech has done a tremendous job in planning this phase out and will continue to repair and supply replacement parts until early 2021.
We all have plenty of time to plan for this phase out! A 10% price increase on the SCM, SCF, SCL series went into effect on May 1, 2016… another incentive to take a look at some of these other series!
- State of the art inverter
- Zero clearance mounting – mount side by side without de-rating
- Save space in your panel
- Fulfills IE2 of new inverter efficiency class
- More motor control possibilities! SLVC, PMAC, closed-loop ASM
- User/OEM configurable ‘favorites’ menu
- New communicaiton possibilities (ProfiBus, EtherCat, EtherNetIP, ProfiNet)
- Easy to use – descriptive keypad text, parameter grouping
- i550 includes an integrated brake chopper
- +24VDC ‘keep alive’ capability
What are the differences between these models?
- The i500 series is a different shape than the SCF/SCM/SCL, it is a ‘bookshelf’ style rather than the cube shape.
- The SCF/SCM/SCL have mounting holes on both sides. The i500 are mounted with fixed key-hole brackets on the top and bottom – this means new mounting holes will need to be drilled.
- The i500 can be mounted side by side with zero clearance and without de-rating! This was not possible with the SCM/SCF/SCL.
- The control wire shield is included as standard on the i500, however, the motor shield plate needs to be ordered separately.
- The connectors are mounted on the same side of the inverter as SCF/SCM/SCL, however, the exact position on the i500 can be different.
- The ‘stop function’ (terminal #1) is a dedicated digital input on the SCF/SCM/SCL. On the i500 every IO function can be freely assigned in parameter 400 (P400)
- The i510 supports PNP/Active High logic only, the i550 supports both PNP/Active High as well as NPN/Active Low logic.
- The parameter numbers have changed, however, the most commonly used SCF/SCM/SCL parameters can be found in the pre-configured Favorites Menu (group 0)
