Determines the maximum encoder feedback signal allowed before a fault occurs; the maximum operation
frequency Pr.01-00 = 100%.

When the drive output frequency exceeds the encoder stall level (Pr.10-10), the drive starts to count the time.
When the error time exceeds the encoder stall detection time (Pr.10-11), the drive implements the encoder stall
action.

● This parameter acts on the settings for Pr.10-13–Pr.10-15:
● 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.
