Baud Rate

Use system variable BR to alter the baud rate of serial communications. Any change made

to the baud rate will only take effect following a save (SV) and system reset or power cycle.

Reset to RS232 Mode

To reset the drive to RS232 mode and to return to factory settings, remove power from the

drive, connect X3 pin 2 to GND and restore power.

CAUTION

This will erase ALL of your user settings and programs in volatile memory. The non-

volatile memory will not be overwritten until a save command is issued.
