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 P7 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 P7 to give desired speed.
Note: It is necessary to set these switches for both tachogenerator and armature voltage
feedback.

Table 4.2 Current Calibration ( * see note on next page )
Example:
Customer wishes to run 14 Amp Motor.
Option 1
Using 512/16 - From table 4.2 set SW7 ON, SW6 ON, SW5 OFF Ia = 14 Amp
Option 2
Using 512/32 From table 4.2 set SW7 OFF, SW6 ON, SW5 ON - Ical = 16 Amp
Turn down I Limit (P4) to give 14 Amps
