●
The DRIVE-CLiQ interface enables components from the SINAMICS drive system to be
connected.
The following components are supported:
– TM15 (digital inputs/outputs)
– TM31 (digital inputs/outputs, analog inputs/outputs)
– TM150 (temperature sensor inputs)
– SMC10 (resolver evaluation for speed actual value sensing)
– SMC30 (incremental encoder evaluation for actual speed value acquisition)
An SMC10 or SMC30 and up to three TMx modules can be connected to each CUD.

Free function blocks (FBLOCKS)
In a wide variety of applications, a logic operation connecting several states (e.g. access
control, system status) to a control signal (e.g. ON command) is required to control the
drive system. However, in addition to logic operations, drive systems require
mathematical operations and memory elements.
These functions are available in the form of the "free function blocks" function module.
A series of elementary function blocks are available that can be freely used:
– Logic function blocks (AND, OR, XOR, inverter)
– Calculation function blocks (adder, multiplier, divider, absolute-value generator)
– Time function blocks (pulse generator, pulse contracting block, ON delay, OFF delay,
pulse stretching)
– Memory function blocks (RS flip-flop, D flip-flop)
– Switch function blocks (binary selector switch, numerical selector switch)
– Control function blocks (limiter, smoothing element, integrator, derivative element)
– Complex function blocks (double-sided limit monitor with hysteresis)
