DIRECTION SIGNALS
This output is TTL/CMOS compatible. The source current rating (Voh = 2.7 V) is 12mA. The sink current rating (Vol =
0.5 V) is 9mA. The Direction signal is +5VDC for '+' or clockwise motion, and 0VDC for '-' or counterclockwise motion.
SOFT LIMIT
This input will cause the motor to ramp down to the base speed. This input contains a 2.5K pullup resistor to +5VDC.
It should be activated by connecting it to the 0VDC pin, or a logic level that can sink 2.0mA at TTL levels.
HOME LIMIT
This is similar to the Hard Limit. It will cause the motor to stop without ramping down. This input contains a 2.5K pullup
resistor to +5VDC. It should be activated by connecting it to the 0VDC pin, or a logic level that can sink 2.0mA at TTL
levels. See the Command Dictionary Section for more information.

HARD LIMIT
When a hard limit switch is encountered, all motion will stop in the given direction. Keep in mind that the motor may
overshoot when this is used. The position given by the position register may not reflect where the motor ended up
stopping due to the overshoot. If an encoder is used, the encoder will reflect the actual motor position. This input
contains a 2.5K pullup resistor to +5VDC. It should be activated by connecting it to the 0VDC pin, or a logic level that
can sink 2.0mA at TTL levels.
