Regulation on rotation speed, using IRE
Let the IRE be of 1000 pulse/revolution and the maximum rotation speed 5000.
The rotation speed should be adjustable between 50 and 3000,
The rotation speed to be kept should be 2000.
The motor should have two poles.
Remark: upon the maximum rotation speed, 5000 corresponds to 100%

For rotation speed regulation, "PI" or "PID" is the most proper regulation type.
Setting of the PID parameters depends on the system, they have always to be adjusted to the actual requirements.
To maintain the high dynamics and avoid swingings be especially careful at setting Td and Ad!
Commands start, stop and directions as well as changing the regulation reference signal can be effected from the
terminal

At setting fmax consider the rotation speed of the motor belonging to its nominal frequency and set the
maximum frequency to a value at which the adjustable maximum rotation speed can still be controlled
securely! (Allowance for the slip)
