Motor Calibrate
A routine motor calibration is not required nor recommended. Control of the motor is entirely digital,
and will not drift with temperature or age of the equipment. In the case of motor controller
replacement or motor replacement to a different speed than that which was supplied from the
factory, a motor calibration should be performed.
Press the
Select
button until the
Calibrate
message (CAL) appears, and then press
Enter
. Press the
Enter
button to start the calibration.
Calibration Operation:
The calibration is separated into 2 steps. Each step will run for 20 seconds in order to give the motor
enough time to stabilize. After the 20 seconds expire, the system will automatically go to the next
step. When all steps are complete, the calibration constants will be saved,
CALIBRATION
mode and
FACTORY
mode exited and the system will return to normal operation.
Step 1:
The first 2 seconds the display will show S1. During this step, the motor will be running at
MAX speed.
Step 2:
The first 2 seconds the display will show S2. During this step, the motor will be running a 10%
of the maximum output.
Step 3:
The display will show ‘
DON
’ for
DONE
, letting the operator know that the calibration is
complete. After 2 seconds, the system will return to normal operation.
During any step in the calibration, the
UP / DOWN
buttons can be used to cancel the calibration,
restoring the system back to normal operation.
