Linear motor drive
LinMot C1200 (C1250 / C1250-MI / C1251)
LinMot's compact DC drive with a multi-interface option that supports many industrial Ethernet protocols on one model. Safety options run from STO to extended functional safety.

Notes on this data
Peak output is 25 Apk (0–599 Hz) per the C1250-MI datasheet v1V1. Some eCatalog titles say '72V/28A' while the data tables say 25 A. No continuous current is published. Options are -0S (no safety), -1S (STO) and C1251-...-2S (extended functional safety). The eCatalog also lists older C1200 variants (NFND/NFNA).
Specify Motion is not affiliated with NTI AG. LinMot and C1200 (C1250 / C1250-MI / C1251) are used only to identify the product. Comparisons use published figures; always confirm against the current datasheet.
Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a LinMot part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
