Chapter 12 Description of Parameter SettingsME300
12.1-10-1
10 Speed Feedback Control Parameters
 You can set this parameter during operation.
In this parameter group, ASR stands for Adjust Speed Regulator and PG stands for Pulse Generator.

Pulse Input Type Setting
Default: 0
Settings
0: Disabled
5: Single-phase pulse input
6: PWM signal input
 When Pr.00-20 = 4, the command source is MI5. Then, you can select external command as
PWM mode through Pr.10-16.
 When you set Pr.10-16 = 0, the function for this parameter is disabled. When you set Pr.10-16 =
5, the pulse input type is single-phase pulse mode with a steady maximum input pulse
frequency of 10 kHz and a corresponding relationship between 0–10 kHz pulse signal and
0–Fmax (Pr.01-00) frequency command. For example, if 10/2 = 5 kHz pulse signal corresponds
to Fmax/2 frequency command, and when the input pulse exceeds 10 kHz, the frequency
command remains at Fmax (Pr.01-00).
 When you set Pr.10-16 = 0, the function for this parameter is disabled. When you set Pr.10-16 =
6, pulse input type is PWM mode. You can set how long the PWM outputs a command after how
many times of averaging and set the period of external PWM both through Pr.07-43. The
average value for frequency command and output speed depends on the settings for these two
parameters. Refer to Pr.07-43 for detailed descriptions.

Top Limit of Frequency Deviation
Default: 20.00
Settings 0.00–100.00 Hz
 Limits the maximum frequency deviation.
 If you set this parameter too high, an abnormal feedback malfunction occurs.

I/F Mode, Current Command
Default: 40
Settings 0–150% rated current of the motor
 Sets the current command for the drive in the low speed area. 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: 5.00
Settings 0.00–600.0 z
 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.
