(2) Two wire control shown. For three wire control use a momentary input on I/O Terminal 02 to command a start. Use a maintained input for I/O Terminal 03 to change direction.
(3) Only one analog frequency source may be connected at a time. If more than one reference is connected at the same time, an undetermined frequency reference will result.
I/O Terminal 01 is always a stop input. The stopping mode is determined by the drive setting.
The drive is shipped with a jumper installed between I/O Terminals 01 and 11. Remove this jumper when using I/O
Terminal 01 as a stop or enable input.
