Axial Flux Start Guide
During Autotune, a slight buzzing noise should come from the motor for approximately half a second and the RUN
light will be lit for the duration of the procedure.
If the fault AT CONTACT FLT is displayed, verify the motor contactor closes during this process
If the fault BRAKE IS OPEN is displayed, the drive has detected motion, verify the brake does NOT lift. If
brake doesn’t lift and minimal movement has occurred, increase BRK FLT LEVEL (A4).
Step 5 –Running
When the above steps have been completed, the drive should be ready to run the motor.
If any faults are displayed whilst running, refer to the troubleshooting section at the end of this guide.
ELSE
If the motor turns, but is running in the wrong direction, change MOTOR ROTATION parameter in C1.
If the motor turns halfway, then stops, check encoder ENCODER PULSES in the A1 menu. This should
match the value in the table above (14,000 to 26,050PPR).
Finally, once running correctly and the installation is close to completion, you can perform full speed runs in both
directions, and check “MEASURED PPR” and “EST INERTIA” in the D1 menu. Monitor these values in both
directions, and take an average of each.
This average value for “MEASURED PPR” should be entered in “ENCODER PULSES”in the A1 menu.
The average value for “EST INERTIA” should be entered in “INERTIA” in the A1 menu.
