Current controller clock cycle
For a current controller clock cycle of 31.25 µs, an SME125 with article number
6SL3055-0AA00-5KA3 must be used.
Note
In order to guarantee the degree of protection, all of the plug connectors must be correctly
screwed into place and appropriately locked.
The maximum cable length for the encoder system interface depends on the current
consumption of the encoder system and the cross-section of the wire in the cable. However, the
maximum length is 30 m. The figure below applies to encoder systems that operate in the supply
voltage range between 4.75 V and 5.25 V. The sample parameters shown are 0.28 mm² cross-
section (0.14 mm² supply plus 0.14 mm² Remote Sense wires) and 0.64 mm² (0.5 mm² supply
plus 0.14 mm² Remote Sense wires).
