Kollmorgen S7240

7.8.5 Mains supply connection (X0), single phase with neutral
The S700 with 230V version (S7xx6) can be operated with a single phase mains supply.
In single phase operation the electrical power of the amplifier is limited.
The table below shows the maximum rated power (Pn) and peak power (Pp) with single
phase operation:

The maximum possible current depends on the motor torque constant k
T
and on the
maximum speed of the connected motor:

Speed can be limited with the ASCII parameter VLIM to reach the necessary current for
the required torque.
With a special motor type (k
T
= constant depending on the motor type) the possible out-
put current depending on speed is similar to the diagram below:
