The Siemens 6SL3211-0KB17-5BB1 is a SINAMICS G110-CPM110 AC drive rated 0.75 kW constant and variable torque on a 200-240 V single-phase supply, with an integrated EMC filter and RS-485 interface running USS protocol. It is designated a spare part, meaning it is built for replacement of an existing G110-CPM110 in the field, not for new-machine integration where a current-series drive would be preferred.
Mounting and cooling constraint
This drive ships with a flat heatsink and is specified for cooling plate installation only — no standard finned heatsink, so it must be mounted against a metal panel or backplate that acts as the thermal sink. The IP20 enclosure and dimensions of 150 x 90 x 101 mm (HxWxD) mean it fits inside a cabinet, but the cooling plate requirement drives the mounting location: the flat rear face needs good thermal contact with a grounded metal surface. Ambient temperature range is -10 to +40 °C.
Drive features and interface
The RS-485 port uses USS protocol, the standard Siemens serial bus for parameter access and speed reference. No analog input is fitted — speed setpoint comes via USS or the digital inputs. The integrated filter means it meets conducted emissions limits without an external EMC filter on a 200-240 V single-phase supply, saving panel space. Overload capability is 150 % for 60 seconds, typical for a light-industrial constant-torque drive.
