updated by autotuning,
please count according to
the following method.
The counter-
electromotive force
constant can be counted
according to the
parameters on the name
plate of the motor. There
are three ways to count:
1. If the name plate
designate the
counter-electromotive
force constant Ke, then:
E= (Ke*n
N
*2π)/ 60
2. If the name plate
designate the
counter-electromotive
force constant E’
(V/1000r/min), then:
E=E’*n
N
/1000
3. If the name plate does
not designate the above
parameters, then:
E=P/√3*I
In the above formulas: n
N
is the rated rotation
speed, P is the rated
power and I is the rated
current.
Setting range: 0–10000
control, which will impact
the control performance
directly.
When P00.15=1 (rotary
autotuning), the set value
of P02.23 can be updated
automatically via
autotuning; when
P00.15=2 (static
autotuning), the set value
of P02.23 cannot be
updated via autotuning,
calculate the value of
P02.23 and update it
manually.
