ADJUSTMENT
Motor noise suppression and measures against EMC and leakage current — Reducing
mechanic resonance
(speed smoothing control) (Pr.653, Pr.654)
653
Speed smoothing
control
0.1% 0
0 to 200%
The torque fluctuation is reduced to reduce
vibration due to mechanical resonance.
654
Speed smoothing
cutoff frequency
0.01Hz 20Hz
0 to 120Hz
Set the minimum value for the torque
variation cycle (frequency).
665
Refer to Pr.52.
779
Refer to Pr.331.
791, 792
Refer to Pr.7 and Pr.8.
Function assignment of external terminal and control — Pulse train output of output
power (Y79 signal) (Pr.799)
799
Pulse increment

0.1kWh 1kWh
0.1kWh,

10kWh,
100kWh,
1000kWh
Pulse train output of output power (Y79) is
output in pulses at every output current
(kWh) that is specified.
IPM motor control — Control method selection (Pr.800)

9
IPM motor test operation (Motor is not
driven even if it is connected.)
20
Normal operation (Motor can be driven.)
IPM motor control — Proportional gain setting for speed loops (Pr.820, Pr.821)
820
Speed control P gain
1
1% 25% 0 to 1000%
The proportional gain during speed control
is set. (Setting this parameter higher
improves the trackability for speed
command changes. It also reduces the
speed fluctuation due to a load fluctuation.)
821
Speed control integral
time 1
0.001s 0.333s 0 to 20s
The integral time during speed control is set.
(Setting this parameter lower shortens the
return time to the original speed when the
speed fluctuates due to external forces. )
867
Refer to Pr.54 to Pr.56.
870
Refer to Pr.43.
872
Refer to Pr.251.
