
10-10
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%.

10-11
Detection Time of MI7 Single-Phase Pulse Input Stall
Default: 0.1
Settings
0.0–2.0 sec.

10-12
MI7 Single-Phase Pulse Input Stall Action
Default: 2
Settings
0: Warn and continue operation
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).

10-13
MI7 Single-Phase Pulse Input Slip Range
Default: 50
Settings
0–50% (0: Disable)

10-14
Detection Time of MI7 Single-Phase Pulse Input Slip
Default: 0.5
Settings
0.0–10.0 sec.

10-15
MI7 Single-Phase Pulse Input Stall and Slip Error Action
Default: 2
Settings
0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
 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.
