1. ‘Parameter auto-tuning’ [S2.10] is ‘1: Auto tuning with run‐
ning motor’ and over current or over voltage occurs, in‐
crease the parameters ‘Acceleration time 1’ [b1.09] and ‘De‐
celeration time 1’ [b1.10].
2. Ensure the motor is stopped before starting auto-tuning; oth‐
erwise auto-tuning may end in abnormal results.
3. In some cases, it is not possible to use auto-tuning. In such
cases, accurate motor parameter values must be entered, to
parameters [S2.00] − [S2.09]. However, the motor’s name‐
plate parameters of the motor must be entered first.

Setting range 0.1 − 1000.0 rpm Minimum unit 0.1 rpm

Set parameters [S2.12] − [S2.15] in the case of vector control with speed
sensor or pulse encoder feedback V/F control.
●
Parameter [S2.12] is used to set the number of pulses per revolution of
the pulse encoder.
● Parameter [S2.13] is used to change the phase sequence, if the encod‐
er phases are reversely connected.
● If the set frequency is larger than ‘Pulse encoder fault detection extent’
[S2.14] and the actual speed is smaller than ‘Pulse encoder fault detec‐
tion extent’ [S2.14] and lasts for ‘ Pulse encoder fault detection time’
[S2.15], the converter will apply fault protection to the pulse encoder.
