Parameters 163
Defines the derivation time for
acceleration(/deceleration) compensation. In order
to compensate for a high inertia load during
acceleration, a derivative of the reference is added to
the output of the speed controller. The principle of a
derivative action is described under parameter
.
Note:
As a general rule, set this parameter to the
value between 50 and 100% of the sum of the
mechanical time constants of the motor and the
driven machine.
The figure below shows the speed responses when a
high inertia load is accelerated along a ramp.
No acceleration compensation:
Acceleration compensation:
0.00 s
0.00…1000.00 s
Acceleration compensation derivation time.
10 = 1 s
Defines the acceleration (or deceleration)
compensation filter time constant. See parameters
8.0 ms
0.0…1000.0 ms
Acceleration/deceleration compensation filter time.
1 = 1 ms
Defines the proportional gain for the speed controller
when an emergency stop is active. See parameter
10.00
1.00…250.00
Proportional gain upon an emergency stop.
100 = 1
No.
