Description
Defines the low limit for critical frequency 3.
Note: This value must be less than or equal to the value of
28.57 Critical frequency 3
Low limit for critical frequency 3.
Defines the high limit for critical frequency 3.
Note: This value must be greater than or equal to the value
of
28.56 Critical frequency 3
High limit for critical frequency 3.
Selects a source that switches between the two sets of
acceleration/deceleration times defined by parameters
28.72...28.75.
0 = Acceleration time 1 and deceleration time 1 are in force
1 = Acceleration time 2 and deceleration time 2 are in force
0.

If the reference increases faster than the set acceleration
rate, the motor will follow the acceleration rate.
If the reference increases slower than the set acceleration
rate, the motor frequency will follow the reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.
