Can one potentiometer be used to operate multiple Altivar drives at slightly different speeds?
Issue:
Can one potentiometer be used with multiple drives at different speeds? Some motors need to always run at lower speeds than other motors.
Product Line:
Altivar drives
Environment:
All serial numbers, all model numbers
Cause:
N/A
Resolution:
Yes.
Connect the potentiometer to one of the drives using the +10, COM and AI1 terminals.
Interconnect the COM and AI1 terminals of the drives so that each drive gets the same 0-10 Vdc reference.
The low speed (LSP) and high speed (HSP) settings of each drive can be set independently to define the 0-10V speed range.
For the ATV212 drive, +10 = PP, COM = CC, AI1 = VIA/VIB, LSP = LL, HSP = UL
See the installation and programming manuals for more information on wiring and programming.
