4: S-curve Accel/Decel C
The motor rated frequency is taken as inflection point of this S-curve, and the set
Accel/Decel time is:
Accel/Decel rate = Motor rated frequency / Accel/Decel time (√)
NOT Accel/Decel rate = Maximum frequency / Accel/Decel time (×)
When set frequency is higher than motor rated frequency, the Accel/Decel time is automatically
adjusted by reducing motor output torque. This is applicable to the situation in which short
Accel/Decel time is required during the speed range higher than motor rated frequency.
Diagram of S-curve C is shown as Fig. 6-16:

When b2-12 is set to 1:
b2-01 (Accel time 1) is enabled when output frequency during Accel is more than or equal to
set value of b2-13, while b2-03 (Accel time 2) is enabled when output frequency during Accel is
less than set value of b2-13.
b2- 02 (Decel time 1) is enabled when output frequency during Decel is more than or equal to
set value of b2-14, while b2-04 (Decel time 2) is enabled when output frequency during Accel is
less than set value of b2-14.
