3.5.5 I²t function
An integrator monitors the current²-time integral of the CMMS-ST controller. As soon as
the parameterised time is exceeded, a warning message is output and the maximum
current is limited to the rated current.
Note
With a threshold of I²t = 80%, the warning message “0190 - I²t at
80%” occurs and the maximum current is limited to the rated
current.
With a threshold of I²t = 100%, the warning message “0310 - I²t
fault motor” occurs and the maximum current is limited to the rated
current.
The I²t time of the motor can be set via the FCT parameterisation software.
3.5.6 Positioning controller
A positioning control system is set above the current controller. Up to 64 positions
(homing + 63 positions) can be selected and run via a trajectory generator. There are also
volatile position data records for positioning via the field bus.
The position records are made up of a position value and a motion profile. The following
parameters can be set for the eight motion profiles:
- Travel speed
- Acceleration
- Deceleration
- Smoothing
- Time
