Chapter 12 Descriptions of Parameter SettingsC2000 Plus
12.1-07-17
07-32
Motor Oscillation Compensation Factor
Default: 1000
Settings 0–10000
0: Disabled
If there are current wave motions which cause severe motor oscillation in some specific area,
setting this parameter can effectively improve this situation. (When running with high frequency or
PG, set this parameter to 0. When the current wave motion occurs in low frequency and high
power, increase the value for Pr.07-32.)
07-33
Auto-Restart Interval of Fault
Default: 60.0
Settings 0.0–6000.0 sec.
When a reset / restart occurs after a fault, the drive uses Pr.07-33 as a timer and starts counting
the numbers of faults within this time period. Within this period, if the number of faults does not
exceed the setting for Pr.07-11, the counting clears and starts from 0 when the next fault occurs.
07-38
PMSVC Voltage Feed Forward Gain
Default: 1.00
Settings 0.00–2.00
Adjusts the PMSVC voltage feedback forward gain, and to meet the demand of rapid feedback
application.
Pr.07-38 = 1.00 means forward feedback = Ke × motor rotor speed
Refer to Section 12-2 “PMSVC adjustment” for details.
07-41
Minimum Frequency for AES
Default: 10.00
Settings 0.00–40.00 Hz
The drive’s output frequency must be larger than Pr.07-41 to make the drive determine whether
to run in a steady-state output frequency.
In general, larger power and voltage can give more energy-savings; lower power and voltage
produce less energy-savings. However, too low power and voltage are not suitable for low-speed
operation because it needs a larger starting current. Pr.07-41 is the parameter that limits the
minimum frequency when AES is enabled (Pr.07-41 to Pr.01-00 is the frequency range – from
minimum to maximum – that you can use for the AES function).
07-42
Delay Time for AES
Default: 5
Settings 0–600 sec.
When the drive runs in a steady-state output frequency, and exceeds Pr.07-42 setting time, the
drive enters the energy-saving mode.
07-43
Targeted Power Factor Angle for AES
Default: 40.00
Settings 0.00–65.00°
