A failed open-loop test would either move the motor in the opposite direction of the command or lock it
onto a phase, one the following plots may apply:
onto a phase, one the following plots may apply:
General recommendation for troubleshooting unsuccessful open loop tests:
1. Re-phase motor and try again
2. An inverted saw tooth response, most times, indicate that the direction sense of the encoder is
opposite to that of the command output.
With Quadrature | Sinusoidal | HiperFace encoders:
Change I7mn0 to 3 from 7 (default) or vice-versa.
Make sure Ixx70 and Ixx71 are correct.
HiperFace sends absolute encoder data on power-up. If the on-going position direction is
reversed, one needs to make sure that the absolute data sent on power-up agrees with the new
direction of the encoder.

With Resolvers:
Change the direction from clock wise to counter clock wise in the first encoder conversion table
entry (see resolver feedback setup section).

With Absolute Serial Encoders (EnDat, SSI, BiSS, Yaskawa):
The Geo Brick Drive has no control on the direction sense of the serial data stream. There are no
software parameters that allow this change. Normally, the direction sense is set by jumpers or
software at the encoder side. In this scenario, the commutation direction has to be reversed to
match the encoder sense. This is usually done by swapping any two of the motor leads and re-
phasing.

3. If the motor locks in position (with an open loop command i.e.#nO5 ) like a stepper motor, then
the phasing has failed, and most times this indicates that the commutation cycle size is setup
wrong (check Ixx70, Ixx71). Also it could indicate that the encoder sense is reversed.

Note
Halls Phasing (where applicable) needs to be re-configured if the
motor direction is reversed.
