Setting procedure of vector control (speed control)

As required
Fig. 5-11:
NOTES The speed command setting range under vector control is 0 to 400 Hz.
The carrier frequency is limited during vector control. (Refer to page 5-222.)
For vector control for a motor with a resolver, refer to the Instruction Manual of the FR-A8APR.

Set the applied motor and encoder.
(Pr. 71, Pr. 359 (Pr. 852), Pr. 369 (Pr. 851)) (Refer to page 2-74.)
Set the overheat protection of the motor. (Pr. 9)
(Refer to page 5-292.)
Set the motor capacity and number of motor poles.
(Pr. 80, Pr. 81) (Refer to page 5-56.)
Set the rated motor voltage and the rated motor frequency.
(Pr. 83, Pr. 84) (Refer to page 2-74.)
Select the control method. (Pr. 800) (Refer to page 5-56.)
Set the operation command. (Refer to page 5-263.)
Set the torque limit. (Pr. 810)
(Refer to page 5-84.)
Perform offline auto tuning. (Pr. 96) (Refer to page 5-67.)
Select online auto tuning. (Pr. 95) (Refer to page 5-465.)
Easy gain tuning (Refer to page 5-100.)
Adjusting the speed control gain manually (Refer to page 5-102.)
Setting procedure of vector control (speed control)
Install a vector control compatible option.
Set Pr. 862 "Encoder option selection" according to the option to
be used (refer to page 5-64).
Set Pr. 71 "Applied motor", Pr. 359(Pr. 852) "Encoder rotation
direction" and Pr. 369(Pr. 851) "Number of encoder pulses"
according to the applied motor and encoder.
Set the rated motor current (A) in Pr. 9 "Electronic thermal O/L
relay".
When using the SF-V5RU or a motor equipped with a thermal
sensor, set Pr. 9 = "0A".
Set the motor capacity (kW) in Pr. 80 "Motor capacity", and set
the number of motor poles in Pr. 81 "Number of motor poles".
(V/F control is performed when the setting is "9999" (initial
value).)
Set the rated motor voltage (V) in Pr. 83 "Rated motor voltage",
and set the rated motor frequency (Hz) in Pr. 84 "Rated motor
frequency".
Select Pr. 800 = "0" (speed control), "2" (speed/torque
switchover) or "4" (speed/position switchover) to enable
speed control.
Select the start command and speed command.
