<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.
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.
(Pr. 80, Pr. 81) (Refer to page 57.)
Select a control method. (Refer to page 57.)
Selection of position command source. (Pr. 419)
Position command by contact input
Set "0" (initial value) in Pr. 419.
Setting of parameter for position feed
(Pr. 465 to Pr. 494).
(Refer to section 4 of
(applied).)
As required
· Set the electronic gear. (refer to section 4 of
· Setting of positioning adjustment parameter (refer to section 4 of
· Gain adjustment of position control (refer to section 4 of
CAUTION
⋅ The carrier frequencies are selectable from among 2k, 6k, 10k, 14kHz for vector control.
(2k and 6kHz for the 75K or more)
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.)
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" (position control) "4" (speed-
position switchover) or "5" (position-torque switchover) for Pr. 800.
Selection of command pulse form.
