Before operation
<Selection method of position control>
In the position control, the speed command is calculated so that the difference between command pulse (or
parameter setting) and the number of feedback pulses from the encoder is zero to run the motor.
This inverter can perform conditional position feed by contact input and position control by inverter conditional
pulse input.
Setting procedure
Perform secure wiring. (Refer to page 32.)
Set the motor and encoder. (Pr. 71, Pr.359, Pr.369)
Set the motor capacity and the number of motor poles according as required.
Select a control method. (Refer to page 58.)
Selection of position command source. (Pr. 419)
Setting of parameter for position feed
(Pr.465 to Pr.494). (Pr. 465 to Pr.494)
(Refer to Instruction Manual (applied).)
As required
· Set the electronic gear. (refer to
· Setting of positioning adjustment parameter (refer to
· Gain adjustment of position control (refer to
62
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 33.)
(Pr. 80, Pr. 81) (Refer to page 58.)
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 "3" (speed control) "4" (speed-
torque switchover) or "5" (position/torque switchover) for Pr.800.
Position command by contact input
Set "0" in Pr. 419 (initial value).
(Refer to
Test run
Instruction Manual (applied))
Position command by inverter pulse train input
Set "2" in Pr. 419.
Selection of command pulse form.
