Caution
During the following set-up instructions, be ready to STOP the drive should the motor try to overspeed.
3.8
Set the speed potentiometer to 5% (0.5V at terminal A8).
3.9
Refer back to 3.1 to display the CONFIGURE DRIVE menu. Slowly increase the MAIN
CURR.LIMIT parameter towards a maximum
of 20%. At some point the motor will begin to
rotate as the parameter value is increased.
The motor speed will
settle at 5%
of full speed.
If the motor is loaded it may require more than 20% current limit to turn the motor.
3.10
Stop the drive by opening C3. Now Autotune the drive.
4: Autotuning
This process tunes the drive to the connected motor. Initial conditions must be:
•
Main contactor open, i.e. terminal C3 = 0V
•
Program Stop (terminal B8), Coast Stop (terminal B9)
and Enable (terminal C5) high, i.e. 24V.
•
No field voltage: Autotune automatically quenches the
(default) internally supplied field.
4.1
Set AUTOTUNE to
ARMATURE.
4.2
Close the main contactor (apply the "Start/Run"
command to C3) to begin the Autotune.
•
The keypad displays “Autotuning” during the process. When Autotune is complete (after approximately 10 seconds),
the main contactor is opened and the AUTOTUNE parameter is reset to OFF. Ensure that "Enable" (C5) is OFF.
4.3
Perform a PARAMETER SAVE now
. Refer back to
3.3
for how to do this.
The drive is powered-up and operating using Armature Volts Feedback.
