Applicable inductive motors for NPS-FI type are NA100, NA20, Hollow shaft
BSM type, and Flat type NA30. |
| （１） |
Speed control range is down to 1:5000
of rated speed and torque is constant in the control range. |
| （２） |
Internal field control circuit can
conduct over-drive up to 3 times of rated speed. And output is constant
in the control range. |
| （３） |
Since it is inductive servomotor,
rotation is smooth by accurate torque ripple (±4%) regulation. |
|
Driver specification
is identical to NPS-FIM/FIH except for electric regenerative energy
control instead of brake control. Other functions are in accordance
with NPS.

This driver works as AC servo controller in motor
run, and as electric regenerative energy unit in regenerative status. When
a servomotor runs as a generator at braking, this driver can return 90 %
of the generated energy to a power company. In the other words, this works
as a dual servo driver and saves energy. |

Common application to NPS and NPSR Engine tester
(dynamometer), Molding machine, Rotary cutter, Servo press, Brake/Clutch
tester, Built in type spindle drive, and other special dynamic machines. |
