12.1-10-1
10 Speed Feedback Control Parameters
 You can set this parameter during operation.

10-16
Pulse Input Type Setting
D
efault: 0
Settings
0: Disabled
(default)
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.

10-29
Upper Limit of Frequency Deviation
D
efault: 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.

10-31
I/F Mode, Current Command
D
efault: 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.

10-32
PM FOC Sensorless Speed Estimator Bandwidth
D
efault: 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.
