6.TT Enhanced Function Parameters (Group Pb)
These parameters are used to avoid mechanical resonance. When the reference frequency between the
jump frequency upper limit and jump frequency lower limit, the motor will run at jump frequency lower
limit when acceleration, run at jump frequency upper limit when deceleration, as shown in the following
figure.
Figure 6−36 Upper and lower limit of jump frequency
When Pb.08 and Pb.T0 setting without integral function, UPTDN single step increase or decrease
frequency define by Pb.06.

Pb.07 ones place is used to enlarge T0 times accelerationTdeceleration time. If Pb.07 ones place is set to T:
The real acceleration and deceleration time= P0.08TP0.09 × PT0
Pb.07 thousands place is used to determine whether the UPTDN can change the running direction.
