3.2.4 Meeting Pulse Tachometer Specifications (Vector Regulation Only)

GV3000 drives set up for vector regulation require a pulse tachometer for closed loop operation.
Pulse tachometer specifications are provided in table A.6. Drives set up for volts/hertz regulation do
not require a pulse tachometer for feedback because they operate in the open loop mode.
3.2.5 Verifying Power Module Output Current Rating is Greater Than Motor Full Load
Amps
Verify that the GV3000 output current rating is greater than the motor's full load current (amps).
Table 2.1 lists the output current values.
