Chapter 12 Description of Parameter SettingsC2000-HS
12.1-10-8
If the application needs a higher setting for Pr. 10-29, note that a higher setting results in larger
motor slip, which causes a PG Error (PGF3, PGF4). In this case, you can set Pr. 10-10 and Pr.
10-13 to 0 to disable PGF3 and PGF4 detection, but you must make sure the PG wiring and
application are correct; otherwise, it may lose the instant PG protection. Pr. 10-29 setting too
high is not commonly done.
Resolver Pole Pair
Default: 1
Settings 1–50
To use the Pr.10-30 function, you must set Pr.10-00=3 (Resolver Encoder) first.
I/F Mode, Current Command
Default: 40
Settings 0–150% of motor rated current
Sets the current command for the drive in low speed area (low speed area: frequency command
< Pr. 10-39). When the motor stalls on heavy-duty start-up or forward/ reverse with load,
increase the parameter value. If the inrush current is too high and causes oc stall, then
decrease the parameter value.
PM FOC Sensorless Speed Estimator Bandwidth
Default: 5.0
Settings 0.0–1500.0 Hz
The upper limit is the same as the maximum operation frequency for Pr.01-00.
Sets the speed estimator bandwidth. Adjust the parameter to change the stability and the
accuracy of the motor speed.
If there is low frequency vibration (the waveform is similar to sine wave) during the process, then
increase the bandwidth. If there is high frequency vibration (the waveform shows extreme
vibration and is like a spur), then decrease the bandwidth.
PM Sensorless Speed Estimator Low-pass Filter Gain
Default: 1.00
Settings 0.00–655.35
Changes the response speed of the speed estimator.
If there is low frequency vibration (the waveform is similar to the sine wave) during the process,
then increase the gain. If there is high frequency vibration (the waveform shows extreme
vibration and is like a spur), then decrease the gain.
ARM (Kp) Gain
Default: 1.00
Settings 0.00–3.00
ARM (Ki) Gain
Default: 0.20
Settings 0.00–3.00
Active Magnetic Regulator Kp / Ki, affects the response of magnetic regulation in the low
magnetic area.
