NOTE
Uneven rotation slightly increases as compared to the V/F control. (It is not suitable for machines such as grinding
machine and wrapping machine which requires less uneven rotation at low speed.
When a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is connected between the inverter and motor, output
torque may decrease.)
Adjustment of the output torque (current) of the motor
Perform secure wiring.
(Refer to page 14)
Set the motor. (Pr. 71)
Motor
Set motor capacity (kW) in Pr. 80 Motor capacity and
the number of motor poles (number of poles) in Pr. 81 Number of motor poles.
(V/F control is performed when the setting is "9999" (initial value).
Set "20" (initial value) in Pr. 800 to make Advanced magnetic flux vector control
valid.
Select the start command and speed command.
(1)Start command
1)Operation panel: Setting by pressing
2)External command: Setting by forward rotation or reverse rotation
command (terminal STF or STR)
(2)Speed command
1)Operation panel: Setting by pressing
2)External analog command (terminal 2 or 4):
Give a speed command using the analog signal input to terminal 2 (or
terminal 4).
3)Multi-speed command:
The external signals (RH, RM, RL) may also be used to give speed
command.
