Detailed instruction of parameters
updated by autotuning,
please count according to
the following method.
The counter-
electromotive
constant can be counted
according to
parameters on the name
plate of the motor. There
are three ways to count:
1. If the name plate
designate
counter-electromotive
force constant Ke, then:
E= (Ke*n *2π)/ 60
N
2. If the name plate
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: No protection
1: Common motor (with low speed compensation).
Because the heat-releasing effect of the common
motors will be weakened, the corresponding electric
heat protection will be adjusted properly. The low
