VALUE
TABLE 4.1 Full speed tachogenerator/armature feedback voltage.
Example:
(a) 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 P10 to give desired speed.
(b) Customer wishes to run motor at 2000rpm with 320V armature.
Feedback voltage = 320V
From Table 4.1 set SW1 ON SW2 OFF adjust P10 to give desired speed.
Note:- It is necessary to set these switches for both tachogenerator and armature voltage feedback.
