Altivar 11 - AC Drive
This section deals with Altivar 11 - AC Drive general information and specific Dryair settings only.
For complete specifications, operating information and Troubleshooting, refer to the "ALTIVAR 11 Adjustable Speed Drive Controllers Start-up
Guide" manual included in the manual case (located behind the access panel).
Precautions
Electric shock will result in death or serious injury.
•
Read and understand the "ALTIVAR 11 Adjustable Speed Drive Controllers Start-up Guide" before installing or operating the
ALTIVAR 11 drive controllers. Installation, adjustment, repair, and maintenance must be performed by qualified personnel.
•
The user is responsible for conforming to all applicable code requirements with respect to grounding all equipment.
•
Many parts in this drive controller, including printed wiring boards, operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
•
DO NOT touch unshielded components or terminal strip screw connections with voltage
present.
•
DO NOT short across terminals PA and PC or across the DC capacitors.
•
Install and close all covers before applying power or starting and stopping the drive
controller.
•
Before servicing the drive controller:
-Disconnect all power.
-Place a "DO NOT TURN ON" label on the drive controller disconnect.
-Lock the disconnect in the open position.
•
Disconnect all power including external control power that may be present servicing the
drive controller. WAIT 15 MINUTES for the DC bus capacitors to discharge. Then follow
the DC bus voltage measurement procedure beginning on page 5 of the "ALTIVAR 11
Adjustable Speed Drive Controllers Start-up Guide" to verify that the DC voltage is less
than 45 Vdc. The drive controller LEDs are not accurate indicators of the absence of DC bus
voltage.
General information
Operating features of the Altivar 11-AC Drive includes:
•
Ability to catch a spinning load after a supply break or on a start command for smooth take-up of a rotating machine.
•
Dynamic braking possible, even for high inertia and unbalanced load applications.
•
Optimal management of the motor due to flux vector control: 150% of the nominal current of the drive during 60 seconds with a 1:20
speed ratio.
Setup-Operation
The drive controller is factory set to the parameters required for optimal performance and minimal down time. The Altivar 11 drive factory
default settings are embedded in the drive controllers main board (EPROM). No power or activity for prolonged periods of time will not
affect the set parameters and therefore reprogramming the controller is not required.
See "Maintenance - Altivar 11 AC Driver, Auto/Manual Resets" section in the operators
manual for auto and/or manual reset procedures.
Auto-feed Control
•
The auto-feed control (4-1) is factory set.
•
If the setting has changed or the control is not activating properly, the plunger setting
needs to be checked:
See "Maintenance - Auto-feed Control" section of the operators manual for plunger
adjustment procedure.
