Caution
As the motor turns the number of revolutions set by this parameter, the hybrid deviation is
cleared to 0. No clearing is made with setup value 0.
<Hybrid deviation clear feature>
As the motor reaches the number of revolutions set by Pr3.29 Hybrid deviation clear setup,
clear the hybrid deviation to 0. This feature allows the motor to be used in an application
where hybrid deviation accumulate due to slippage, etc.

Note: Revolution in the hybrid deviation clear setup is counted by using encoder feedback pulses.
To use the hybrid deviation clear, be sure to set Pr3.29 Hybrid deviation clear setup to the
appropriate value. If the setup value is too small with respect to the value of Pr3.28 Hybrid
deviation excess setup, abnormal operation due to e.g. external scale connection error
cannot be protected.
Limit sensor should be used to assure safety.
