When P00.15=2, the set value of P02.23 cannot be
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
