Drive Spec at a Glance
The Siemens 6SL3211-0KB15-5UB0 is a SINAMICS G110 CPM110 AC drive rated 0.55 kW for both constant-torque (CT) and variable-torque (VT) loads, fed from a single-phase 200-240 VAC supply at 47-63 Hz. It carries a 150% overload capability for 60 seconds — enough headroom to start a loaded conveyor or pump without oversizing the drive frame. Communication is via RS485 using the USS protocol, which ties it into a Siemens PLC or HMI without an extra gateway module.
Mounting and Environment
Housed in a 150 x 90 x 101 mm (HxWxD) IP20 enclosure without an integrated heatsink — it relies on panel airflow or a backplate for thermal dissipation, so leave clearance above and below for natural convection. Ambient temperature range is -10 to +50 °C without the optional BOP (Basic Operator Panel); derate if you add the BOP or mount in a sealed cabinet.
