Chapter 12 Inverter Function
Set-up of functions of the encoder feedback.
Check the encoder's set-up from the encoder's
specifications.
Set up the control method.
(1) Check the encoder's or the pulse trains' input specs.
(2) Open collector input
(See, "7.7.3 Wiring portion under the
controller circuit.")
(3) Line driver input
(See, P1-FB's instruction manual)
Control using the P1 main body's terminals
[A] and [B]
⇒
Set [CA-90] = 02.
Control using P1-FB's [EAP], [EAN], [EBP], and
[EBN]
⇒
Check that [CA-90]
≠
02.
(1) Check whether the speed control or the position control is to be conducted with the control with sensor.
(2) Conduct the speed control with sensor.
In accordance with the mode to be used,
select one of the following three controls:
• V/f control with sensor ([AA121] = 04 to 06)
• Automatic boost with sensor ([AA121] = 07)
• Vector control with sensor ([AA121] = 10)
(see, "12.9.1 Selection of control mode.")
* When [AA121] = 10, the vector control mode
selection [AA123] = 00.
(3) Conduct the absolute position control.
Select the vector control with sensor ([AA121] = 10),
and set as the vector control mode selection [AA123]
either
• 02: Absolute position control; or
• 03: High-resolution absolute position control
(See, "12.17.8 Stop at predetermined position)
