Heavy mains starting (CS)
The CS function is used for starting drives with an extremely high
starting torque directly from the mains. This means that a smaller,
less expensive frequency inverter can be used, since the DV6 has
to deliver only the motor full load current, not the high starting
current (for example 50 A starting current, 15 A motor full load
current).
To use this function, the system must be wired as shown in
Figure 81.
