The bit-rate for communication is 57600 baud (factory preset). Other bit-rates are possible. To prevent
interference it is advised to keep cable length at 3m or less. Shielding interface cables is highly
recommended. It is also advised not to run the interface cable next to high power or AC signals such as
servo amplifiers, line voltages etc.
The wiring from PC to drive connector X6 for serial interface must be as shown below:
A) RS232
RS232 is the standard interface.
CAUTION : The serial connector on the SC610 (X6) can be configured as either

certain keypad peripherals. Ensure that pin 9 is not connected to
ground or to equipment that could be damaged by the +8V supply
