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.
If the failure persists (inverted saw
tooth, as shown in the plot), or you
observe oscillations in the
response instead of a saw tooth,
then most likely the direction
sense of the encoder is opposite to
the command output.
Unsatisfactory Open Loop Test Result
General recommendation for troubleshooting an unsuccessful open loop test
An inverted saw tooth response, most times, indicates that the direction sense of the encoder is opposite to
that of the command output.

Quadrature | Sinusoidal:
Change I7mn0 to 3 from 7 (default) or vice-versa.

Absolute Serial Encoders (EnDat, SSI, BiSS, Yaskawa, Panasonic, Tamagawa, Mitutoyo):
The Turbo PMAC Clipper has no control on the direction sense of the serial data stream
(packets). There are no software parameters that allow changing the direction sense of absolute
serial encoders. Normally, it is set by jumpers or software at the encoder side.
Some amplifiers allow swapping the DAC+ and DAC- signal to invert the direction travel of the
motor. Otherwise, two of the motor leads have to be swapped.
