Customer wishes to run motor at 1500rpm with a 60V/1000rpm tachogenerator.
Feedback voltage = 90V
From Table 4.1 set SW1 OFF SW2 OFF adjust P7 to give desired speed.
Customer wishes to run motor at 2000rpm with 320V armature.
Feedback voltage = 320V
From Table 4.1 set SW1 ON SW2 OFF adjust P7 to give desired speed.
