Video: How to setup a ramp switching functionality on an ATV320 drive?
Issue:
Setting up ramp switching functionality on an ATV320 drive.
Product Line:
Altivar 320
Environment:
All
Cause:
Customer wanted a second deceleration with the drive.
Resolution:
This functionality allows activation of two different acceleration and deceleration rates based on a logic input or a frequency threshold.
In the SEt menu, parameters ACC and dEC are the first set of rates.
The ramp switching is programmable under ConF, FULL, FUn-, rPt-.
Parameter rPS is a ramp switching assignment for a logic input (LI1 thru LI6) or integrated communications.
Parameters AC2 (Acceleration 2) and DE2 (Deceleration 2) are the second set of rates. The ATV320 uses ACC/dEC until the rPS assigned input goes active, at which point it uses AC2/dE2. Deactivating the input goes back to ACC/dEC rates.
Parameter Frt is a ramp 2 threshold activated when assigned a value other than 0Hz. The ATV320 will use ACC/dEC when the output frequency is below Frt, but switch to AC2/dE2 when the output frequency is above Frt.
Note that if rPS is assigned and is at a logic state active, it will override the Ramp 2 Threshold setting (Frt) and the ATV320 will use AC2/dE2, regardless of the motor speed.
