Test run
Mount the FR-A7AP.
Set Pr. 71 "Applied motor", Pr. 359 "Encoder rotation direction" and Pr.
369 "Number of encoder pulses" according to the motor and encoder
used. (Refer to page 3-42.)
Set the motor capacity (kW) in Pr. 80 "Motor capacity" and set 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).
Make speed control valid by selecting "0" (speed control), "2" (speed-
torque switchover), or "4" (speed-control switchover) for Pr. 800.
Select the start command and speed command.
1) Start command
– Operation panel: Setting by pressing FWD/REV of the operation
panel
– External command: Setting by forward rotation or reverse rotation
command (terminal STF or STR)
2) Speed command
– Operation panel: Setting by pressing the digital dial of the operation
panel
– External analog command (terminal 2 or 4) :
Give a speed command using the analog signal input to terminal 2
(or terminal 4).
– Multi-speed command:
The external signals (RH, RM, RL) may also be used to give speed
command.
