AφR time
constant
Set the factor to multiple
times the secondary circuit
time constant of the motor to
achieve the AφR time
constant.
AφR time constant =
Secondary circuit time
constant x d6-05
AφR will not function when
d6-05 is 0. If d6-05 is not 0,
the lower limit of the value
will be internally adjusted to
200 ms in the Inverter.
