0: Disabled
5: Single-phase input (MI7)
 When Pr.10-16 = 5, you cannot set Pr.10-02 to 5: Single-phase input (MI7) for closed-loop
control.
 The setting steps when using the MI7 single-phase pulse input as the frequency command:
1. Set Pr.00-20 = 4: Pulse input without direction command
2. Set Pr.10-00 = 5: Pulse input (MI7)
3. Set Pr.10-01 to motor pulses per revolution (ppr)
4. Set Pr.10-16 = 5: Single-phase input (MI7)
5. Set Pr.00-04 = 22 (Pulse input frequency) to verify if the pulse input frequency is correct.

 Rotation speed = pulse frequency ÷ MI7 single-phase pulse input pulses (Pr.10-01) × electrical
gear A / electrical gear B.

Pulse Input Speed Command Low Pass Filter Time
Default: 0.100
Settings
0.000–65.535 sec.
 When you set Pr.00-20 to 4, the system treats the pulse command as a Frequency command.
Use this parameter to suppress the speed command jump.

FOC sensorless mode with crossing zero means the speed goes from negative to
positive or positive to negative (forward to reverse direction or reverse to forward
direction).
0: determined by the stator frequency; 1: determined by the speed command

Direction control in open-loop torque
0: Switch ON direction control; 1: Switch OFF direction control
 Only bit = 0 is used for closed-loop; other bits are used for open-loop.
