2.5 MECHATROLINK Transmission Cycle and the Number of Connected Slave Stations
2.4.3 Mixed Cascade/Star Connections
2-18
Mixed Cascade/Star Connections
*1. Up to 16 Servo Drive stations can be connected.
*2. Up to 32 Servo Drive stations can be connected.
Note: The above connection conditions assume that the following conditions are met: Number of transmission
bytes: 48, Distance between stations: 100 m., Number of retries: 1.

If the SigmaWin+ is connected through the MP3000, the SigmaWin+ may not be usable if there
are too many SERVOPACK stations connected.
If this occurs, either connect the SigmaWin+ to the SERVOPACK (CN7) directly, or lengthen the
transmission cycle.
