Description
The torque fluctuation is reduced to reduce
vibration due to mechanical resonance.
Set the minimum value for the torque
variation cycle (frequency).
Pulse train output of output power (Y79) is
output in pulses at every output current
(kWh) that is specified.
IPM motor test operation (Motor is not
driven even if it is connected.)
Normal operation (Motor can be driven.)
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.)
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. )
