Detailed instruction of parameters
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
designate
counter-electromotive
force constant Ke, then:
E= (Ke*n *2π)/ 60
N
2. If the name
designate
counter-electromotive
force constant
(V/1000r/min), then:
E=E'*n /1000
N
3. If the name plate does
not designate the above
parameters, then:
E=P/√3*I
In the above formulas: n
is the rated rotation
speed, P is the rated
power and I is the rated
current.
Setting range: 0–10000
0–FFFFH (reserved)
0%–50% (the rated current of the motor) (reserved)
0: No protection
1: Common motor (with low speed compensation)
2: Variable-frequency motor (without low speed
compensation)
Motor overload multiple M = Iout/(In × K)
In is the rated current of the motor, Iout is the output
current of the VFD and K is the motor overload
protection coefficient.

is no need to change
the value of P12.23;
plate when P00.15=2, the set
the value of P12.23 cannot
be updated
autotuning,
account and update the
