● 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:
– Set Pr.00-20=4: Pulse input without direction command
– Set Pr.10-00=5: Pulse input (MI7)
– Set Pr.10-01 to motor pulses per revolution (PPR)
– Set Pr.10-16=5: Single-phase input (MI7)
– Set Pr.00-04=22 (Pulse input frequency) to verify if the pulse input frequency is correct.

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.

N/A
11
Activates the DC brake when executing the zero torque command.
0:ON; 1:OFF
12
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.
