Open-Loop Test, Encoder Decode: I7mn0
Having a satisfactory current loop, the motor can now be manually phased (i.e. custom, 2-guess,
stepper method) as described in the subsequent Motor Phasing section. The open-loop test is
critical to verify the direction sense of the encoder counting versus the command output.
A positive command should create a positive velocity and a position counting in the positive
direction; a negative command should create a negative velocity and a position counting in the
negative direction. The open-loop test can be done manually from the terminal window while
gathering position, velocity data. However, the PMACTuningPro2 Software provides with a
built-in automatic open loop utility that is convenient to use.

Acceptable Open-Loop Result, Correct Encoder Decode (I7mn0)
The open-loop test is usually performed on an unloaded motor. The open loop command output
is adjustable, start off with a conservative 1 to 2 percent command output (i.e. #nO2) value and
increment gradually until you see a satisfactory result.
