 When the value of (rotation speed – motor frequency) exceeds Pr.10-13 setting, detection time
exceeds Pr.10-14; it will start to accumulate time. If detection time exceeds Pr.10-14, the encoder
feedback signal error will occur. Refer to Pr.10-15 encoder stall and slip error treatment.

 When this setting is different from Pr.10-01 setting and the source of the frequency command is
pulse input (Pr.00-20 is set to 4 or 5), it may have 4 times frequency problem.
Example: Assume that Pr.10-01=1024, Pr.10-02=1, Pr.10-16=3, Pr.00-20=5, MI=37 and ON, it
needs 4096 pulses to rotate the motor a revolution.
