FAQ for R88M-K40030H-S2

Which drive pairs with the R88M-K40030H-S2?
Any Accurax G5 400 W drive. The R88D-KN04H-ECT for EtherCAT networks, the R88D-KN04H-ML2 for MECHATROLINK-II or the R88D-KT04H for analog / pulse. The drive and motor share the same 400 W power class and use the R88A-CAKA power cable and R88A-CRKA encoder cable.
Does the R88M-K40030H-S2 have a brake?
No. The H suffix marks no holding brake. For vertical axes that need to hold position when de-energised, use the R88M-K40030H-BS2 (with 24 VDC brake). The brake draws 0.3 A at 24 VDC and adds about 300 g.
What does the -S2 suffix mean on the shaft?
S2 marks a 14 mm straight shaft with keyway. The S1 suffix is a smooth round shaft. Use the keyway shaft when the load couples through a pulley or pinion that needs a keyed connection.
