PARAMETER
(2) Selection method of vector control
Set any of 0 to 5 in [
Pr. 800 Control method selection
].
Setting any value other than 9999 in [
Pr. 80 Motor
capacity
] and [
Pr. 81 Number of motor poles
] selects
vector control. V/F control is chosen when either of
the [
Pr. 80 or 81
] setting is 9999.
When [
Pr. 81 = 12, 14, 16, 18, 20
], you can select
between V/F control and vector control for operation
by switching ON-OFF the X18 signal.
Set [
Pr. 71
,
359, 369
] according to the motor and
encoder used.
Vector control is controlled by the encoder at motor
side. When performing vector control with the
encoder on the machine side by using FR-A7AL,
convert the number of encoder pulses at the machine
side to the number equivalent for the motor side, and
set the value to [
Pr. 396 Number of encoder pulses
].
When encoders at the motor side and machine side
differ, set the same rotation direction as the motor
side to [
Pr. 359 Encoder rotation direction
].
(3) Information on vector control
The carrier frequencies are selectable from 2k,
6k, 10k, 14kHz for vector control. (2k and 6kHz
for the 75K or more)
