The time when the inverter slows down can be adjusted by setting the deceleration point. When the motor
inertia is greater, the deceleration point can be appropriately reduced to make the motor run slowly in
advance;
While it can also be adjusted by setting the sliding frequency (P0.15 lower limit frequency) and the amount of
deviation (P6.06). When the motor has overshoot, set P6.06 to a negative value; when a negative value is
unreachable, set it to a positive value. Suppose that a motor has overshoot, the run procedure is as shown in
Fig. 5-6-2 after setting relevant parameters:

Tips:
The actual length can be cleared by multi-function input terminal (Define terminal Xi as No.52 function). The actual
length will be calculated only after this terminal is disconnected.
Actual length (setting of P6.01) will be saved automatically when the power is off. If the operation frequency is
greater than frequency upper limit and no pulse is input after the running time is longer than 30 seconds, the inverter
reports pulse coder fault (dE) when actual length is 0.
