Examples of speed controller settings
A few examples of speed controller settings with vector control without encoders (p1300 =
20) are provided below. These should not be considered to be generally valid and must be
checked in terms of the control response required.
● Fans (large centrifugal masses) and pumps
Kp (p1470) = 2 ... 10
Tn (p1472) = 250 ... 500 ms
The Kp = 2 and Tn = 500 ms settings result in asymptotic approximation of the actual
speed to the setpoint speed after a setpoint step change. During many simple control
procedures, this is satisfactory for pumps and fans.
● Stone mills, separators (large centrifugal masses)
Kp (p1470) = 12 ... 20
Tn (p1472) = 500 ... 1000 ms
