Technical data

8.8.5 Mains supply connection (X0), single phase with neutral
S300 with 230V version (SERVOSTAR 303-310) 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:
