66.03 PROF ACC WEAK SP
Defines a positioning speed value (for the profile generator), above which the acceleration/
deceleration time is reduced. Because the drive power depends on the torque and angular velocity,
this parameter defines the power limit used in the position reference calculation.
ω
P = T × and T = J × d
T = torque
ω
= angular speed
J = Inertia
ω
d /dt = angular acceleration
I.e. when the angular velocity exceeds the defined speed value, the power is limited by reducing the
angular acceleration(/deceleration).
The unit depends on parameter
0...32768
66.04 POS WIN
Defines the absolute value for the positioning window supervision. When the final position is within the
limits defined by this parameter, the positioning is completed.
Parameter value must be smaller than the value set by parameter
The unit depends on parameter
0...32768
66.05 POS ENABLE
Selects the source for enabling the position reference generator and the calculation of the position
reference.
1 = Enable / Continue position reference calculation.
0 = Disable. Position reference calculation is stopped. Generator output speed is decreased to zero
along the position deceleration ramp.
Bit pointer: Group, index and bit.
