2. Encoder Pole Position Learn – (Optional)
The Encoder Pole Position Learn is only used when the car is balanced or the
ropes have not been installed as this procedure requires frictionless movement
(un-roped sheave or balanced car). It sets the correct A/B channel phasing in
addition to the pole position.
Begin the procedure by setting:
• LL06 - Encoder Pole Position Learn = Start
The user will be prompted to:
“Press and hold the inspection (direction + enable button) until finished.”
The controller speed should still be at “0” FPM.
If the A/B phasing is incorrect the process will stop and notify the user. Then it
will resume and automatically make the change and prompt the user to hold
the inspection buttons again.
When the process is complete, the keypad will prompt the user to release the
inspection buttons.
Proceed to Section #3 “Encoder Synchronization” for further details.
If the Encoder Synchronization process has previously been completed, the user
may abort the Encoder Synchronization step without losing the learned Encoder
Pole Position.
3. Encoder Synchronization
The Encoder Synchronization process will determine the correct A/B encoder
channel phasing and direction of rotation for PM motors and immediately
follows either method of learning the encoder pole position.
Begin the process by setting:
• LL07 - Encoder Synchronization to “Start”
Follow the directions on the keypad. The drive will run the elevator and swap
the phasing and direction of the A/B channels as needed.
Turn on the BR and EBR breakers and return the inspection speed to
factory setting on the controller.
SETUP OF THE ENCODER LEARN IS NOW COMPLETE!
