Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1486, p1487, p1488, p1489, p1492
p1492[0...n] BI: Droop feedback enable / Droop enable
Access level: 3
Can be changed: U, T
Unit group: -
Min
-
Description: Enables the droop to be applied to the speed/velocity setpoint.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1486, p1487, p1488, p1489, r1490
Note: Even when not enabled, the droop speed is calculated but not subtracted from the setpoint speed. This makes it
possible to subtract the result of this calculation from the speed of another drive.
r1493 CO: Moment of inertia total, scaled / M_inert tot scal
Access level: 3
Can be changed: -
Unit group: 25_1
Min
- [kgm²]
Description: Display and connector output for the parameterized total moment of inertia.
The value is calculated as follows: (p0341 * p0342) + p1496
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
p1496[0...n] Acceleration pre-control scaling / a_prectrl scal
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.0 [%]
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0341, p0342
Warning: The acceleration precontrol r1518 is kept at the old value if the ramp-function generator tracking (r1199.5) is active or
the ramp-function generator output is set (r1199.3). This is used to avoid torque peaks. Depending on the application,
it may therefore be necessary to disable the ramp-function generator tracking (p1145 = 0) or the acceleration
precontrol (p1496 = 0).
The acceleration precontrol is set to zero, if the Vdc control is active (r0056.14/15).
Note: The parameter is set to 100% by the rotating measurement (refer to p1960).
The acceleration pre-control may not be used if the speed setpoint manifests significant ripple (e.g. analog setpoint)
and the rounding-off in the speed ramp-function generator is disabled.
We also recommend that the pre-control mode is not used if there is gearbox backlash.
p1498[0...n] Load moment of inertia / Load M_inertia
Access level: 3
Can be changed: U, T
Unit group: 25_1
Min
0.00000 [kgm²]
Description: Sets the load moment of inertia.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
