2.2 List of parameters
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
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [kgm²]
Description: Display and connector output for the parameterized total moment of inertia.
The value is calculated as follows: (p0341 * p0342) + p1496
The scaling is not take into account using p1497.
p1495[0...n] CI: Acceleration pre-control / a_prectrl
VECTOR_G (n/M) Can be changed: T
Data type: Unsigned32 / FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
-
Description: Sets the signal source for the acceleration pre-control.
Dependency: The signal source for the acceleration is activated with p1400.2 = 1.
For p1400.2 = 0, the acceleration pre-control is calculated from the speed setpoint change from r0062.
For p1400.2 = 0 and activate reference model (p1400.3 = 1) the acceleration pre-control is switched out.
Refer to: p1400, p1496
Note: If the acceleration is entered as external signal, then the accelerating torque is calculated as follows (r1518):
r1518 = acceleration (% of p2007) / 100 % * (p2007 * 60 s) / p0311 * r0345 / 1 s * r0333
p1496[0...n] Acceleration pre-control scaling / a_prectrl scal
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.0 [%]
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency: When the reference model is activated (p1400.3 = 1) and for an internal acceleration pre-control (p1400.2 = 0), the
acceleration pre-control is switched out (disabled). The reference model (p1400.3 = 1) and external acceleration pre-
control (p1400.2 = 1) can be operated together.
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.
