Appendix
– PM Alignment Procedure
12
During the Alignment, a loud high pitch beep will
come out of the motor and the RUN LED will be
lit for the duration of the procedure.
Open Loop Alignment
Open Loop Alignment is a function that will
locate the motor poles by spinning the motor.
This requires that the ropes be off the motor
sheave and that the brakes are lifted/picked
when performing the alignment. Open Loop
may be enabled two different ways, one way is
to enable the function through the operator and
the other is to enable it by giving the drive a
run command. In order for the function to
properly work, all faults must be cleared, the
brake must be picked and the motor contactor
must pull in.
1) In order to accurately measure the
alignment, the motor has to operate in a
no-load condition. This can be achieved by
removing the ropes from the sheave of the
motor
2) Press the RIGHT or LEFT arrow until the
U0 menu is displayed.
3) Press the UP or DOWN arrow in the U0
menu to find Alignment (U10) sub-menu.
Press ENTER, then the UP arrow to
display:
Verify ALIGNMENT METHOD is set to
OPEN LOOP.
Scroll to ALIGNMENT and press ENTER
to change parameter ALIGNMENT from
DISABLE to ENABLE. Press ENTER.
Press the DOWN arrow to start the
alignment procedure. The operator will
display:
Note: If the operator displays the following
screen, verify ALIGMENT (U10) is set to
enable, there are no active faults (FAULT
LED is off), and the drive is not in a RUN
mode (RUN LED is off).
Press ENTER to change the data from NO
to either
YES
or
ON RUN
.
Note: For either selection, any speed
command issued to the drive will be
ignored, however it may be necessary for
the car controller to anticipate the motor
moving at 1/8
th
rated motor speed (A5).
4) If
YES
is selected, the motor will
immediately start applying current to the
motor and calculating the alignment value.
5) If
ON RUN
is selected, the drive expects
the following items to occur:
a. Car Controller asserts DRIVE ENABLE
b. Car Controller issues Run Command
