Test run
Perform secure wiring. (Refer to page 36.)
Set the motor and encoder. (Pr. 71, Pr. 359, Pr. 369)
Set the run command. (Refer to page 313.)
As required
· Perform offline auto tuning. (Pr. 96) (refer to page 189).
· Select online auto tuning. (Pr. 95) (refer to page 199).
· Easy gain tuning (refer to page 105)
· Manual input speed control gain adjustment (refer to page 108)
Select the start command and speed command.
(1) Start command
1)Operation panel: Setting by pressing / of the
operation panel
2)External command: Setting by forward rotation or reverse
rotation command (terminal STF or STR)
(2)Speed command
1)
Operation panel: Setting by turning of the operation panel
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.
Set the motor capacity and the number of motor poles
(Pr. 80, Pr. 81) (Refer to page 92.)
