Chapter 8 MODBUS Communications|ASDA-AB Series
8-4 Revision January 2009
NOTE
1) The maximum cable length is 100m (39.37inches) when the servo drive is installed in a location where
there are only a few interferences. Please note, RFI / EME noise should be kept to a minimum,
communication cable should kept apart from high voltage wires. If a transmission speed of 38400 bps or
greater is required, the maximum length of the communication cable is 15m (50ft.) which will ensure the
correct and desired baud rate.
2) The number shown in the pervious figure indicates the terminal number of each connector.
3) The power supply should provide a +12V and higher DC voltage.
4) Please use a REPEATER if more than 32 synchronous axes are required.
5) For the terminal identification of CN3, please refer to Section 3.5.
