The ZETADYN 2CF is the asynchronous half of Ziehl-Abegg’s second-generation lift drive pair, alongside the synchronous ZETADYN 2SY. It is a complete unit: an IGBT power section, a control board carrying the travel-curve computer, an integral mains choke, a type FEF radio interference filter and two motor contactors.
Those contactors are the one part that can be left out; the G build omits them. Eight sizes cover 13 A to 74 A, about 5.5 kW to 37 kW at 400 V, in S4 and G4 builds, with overload of 1.8 times rated current for ten seconds. The 2CF takes sine-wave encoders of 1024 to 8192 increments per revolution, or HTL and TTL encoders of 1024 to 2048.
Ambient rating is 0 to 40 degrees C, extending to 55 degrees C at a quarter of rated power, which is tighter than the ZETADYN 3 and 4 generations that followed, so do not assume a like-for-like thermal envelope when specifying a replacement.
Field-oriented closed-loop control for asynchronous lift machines
Full rated motor torque available at standstill
Overload to 1.8 times rated current for a maximum of 10 seconds
Integral line reactor with 4 per cent short-circuit voltage and a type FEF interference filter
Available with integrated motor contactors (S build) or without them (G build)
Sine-wave encoders of 1024 to 8192 increments, or HTL and TTL of 1024 to 2048

† These electrical, loss and dimensional figures come from the manufacturer's joint ZETADYN 2CF / 2SY appendix A1 data table, reconstructed from two independent mirrors of the manual which agree on every value. Please confirm them against the documentation supplied with your own unit before relying on them. Values marked * are the small enclosure variant. Figures apply to sizes 013 to 074; the larger 110 A frame has its own manual and is not covered here.
