2.2 List of parameters
Description: Sets the smoothing time for the actual speed of the speed controller for encoderless closed-loop speed control.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the
speed controller must also be increased (e.g. using p0340 = 4).
Description: Sets the P gain of the speed controller for the upper adaptation speed range (> p1465).
The entry is made referred to the P gain for the lower adaptation speed range of the speed controller (% referred to
p1470).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1464, p1465
Note: If the upper transition point p1465 of the speed controller adaptation is set to lower values than the lower transition
p1464, then the controller gain below p1465 is adapted with p1461. This means that an adaptation can be
implemented for low speeds without having to change the controller parameters.
Description: Sets the integral time of the speed controller after the adaptation speed range (> p1465).
The entry is made referred to the integral time for the lower adaptation speed range of the speed controller (%
referred to p1472).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1464, p1465
Note: If the upper transition point p1465 of the speed controller adaptation is set to lower values than the lower transition
point p1464, then the controller integral time below p1465 is adapted with p1463. This means that an adaptation can
be implemented for low speeds without having to change the controller parameters.
Description: Sets the lower adaptation speed of the speed controller.
No adaptation is effective below this speed.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1461, p1463, p1465
Note: If the upper transition point p1465 of the speed controller adaptation is set to lower values than the lower transition
point p1464, then the controller below p1465 is adapted with p1461 or p1463. This means that an adaptation can be
implemented for low speeds without having to change the controller parameters.
