EVP set point.
Example 1:
The lowering output is set to ANALOG and the descent request consists of a step
whose width corresponds to MAX EVP.
The current is immediately set to the MIN EVP and then it is increased up to MAX
EVP in the time set by the OPEN DELAY parameter.
In the same way, if the actual set point applied is the maximum and the lowering
request is removed all at once, the current is reduced to minimum with a time
delay equal to CLOSE DELAY and then is set to zero.
Example 2:
The lowering output is set to ON/OFF.
As soon as the lowering request is applied, the current will increase from zero to
MAX EVP in the time frame correspondent to OPEN DELAY value.
In the same way, when the lowering request is removed, the set point current is
reduced to zero with a time delay equal to CLOSE DELAY.
9.13 Torque Profile
By setting the proper parameter, it is possible to define a limit for the maximum
torque demand (through set points) in the weakening area, for matching two
goals:
1. Not overtaking the maximum torque profile of the motor.
Superimposing a limiting profile to the maximum torque as to get different
drive performances (Eco mode, Medium performance, High performance).
