4.1 Starting Procedures
Two ways to place the Microspeed Plus into function:
•
If the drive has already been pre-adjusted for its motor and
has accompanying connection sheet, proceed with chapter on
"Starting procedures".
•
If the drive hasn't been pre-adjusted for its motor, first consult
the chapter on "Personalization and Settings" and Chapter 5.0
4.0 Preliminary Checks
The standard drive is furnished with the following
characteristics:
•
Nominal and Peak current of drive corresponds to the drive
size; "RIN and RIP resitors are not mounted".
Ex.: Microspeed Plus 140 10/20A ; 20A peak for 2 seconds, 10A
upon return.
•
Encoder speed adjustment for 3000 rpm at 10V ref. with
encoder of 1000 Imp/rev. "RDT resistor = 22Kohm".
•
KV and DER positions are "1".
How to proceed
What to check
Verify that all signal and power connection terminals are
accurately closed/tightened and execute a visual check of the
drive's cabling.
Start up procedures
•
Remove load from motor shaft and be prepared to quickly
shut off power supply if required. (Warning: keep motor well
fixed to the ground/floor or attached to a mechanical support).
•
Insert the fuses in series with alternating power or insert
the corresponding thermal magnet, insuring the available
power value by measuring with a tester.
