MI7 Single-Phase Pulse Input Stall Level
Default: 115
Settings
0–120% (0: Disable)
 Determines the maximum MI7 single-phase pulse input feedback signal allowed before a fault
occurs; the maximum operation frequency Pr.01-00 = 100%.

1: Fault and ramp to stop
2: Fault and coast to stop
 When the drive output frequency exceeds the MI7 single-phase pulse input stall level (Pr.10-10),
the drive starts to count the time. When the error time exceeds the MI7 single-phase pulse input
stall detection time (Pr.10-11), the drive implements the MI7 single-phase pulse input stall action
(Pr.10-12).

 When the value of (rotation speed – motor frequency) exceeds the Pr.10-13 setting, and the
detection time exceeds Pr.10-14; the drive starts to count the time. If the detection time exceeds
Pr.10-14, the encoder feedback signal error occurs.
