Description: Sets the configuration of the technology controller.
Bit field: Bit Signal name 1 signal 0 signal FP
04 Ramp-up/ramp-down function generator bypass Deactivated Activated -
05 Integrator active for skip speeds Yes No -
06 Internal controller limit not displayed Yes No -
07 Activate Kp adaptation Yes No 7958
08 Activate Tn adaptation Yes No 7958
Dependency: For bit 04 = 0:
The setting is only effective when the PID controller is deactivated.
CAUTION
For bit 04 = 1:
The PID controller can oscillate if the ramp-up and ramp-down times of the speed setpoint channel are not taken into
account when setting controller parameters p2280 and p2285.
Note
For bit 04 = 0:
The ramp-function generator in the speed setpoint channel is bypassed when the technology controller is operational.
As a consequence, ramp times p1120, p1121 are not taken into consideration when configuring the controller.
For bit 04 = 1:
The ramp-function generator in the speed setpoint channel is not bypassed when the technology controller is
operational.
As a consequence, the ramp-up and ramp-down times (p1120, p1121) remain effective, and must be taken into
account as controlled system variables when setting the PID controller parameters (p2280, p2285).
The enable ramps of the PID controller are ensured in this setting by p1120, p1121 as well as rounding functions p1130
and p1131. The ramp-up/ramp-down time of the PID controller limiting p2293 must be set appropriately shorter, as
otherwise this has an impact on the speed setpoint channel.
For bit 05 = 0:
The integral component of the PID controller is held if a skip band or the minimum speed range is passed through in
the speed set point channel.
This prevents the speed from oscillating between the edges of the skip band.
For bit 05 = 1:
The setting is only effective if a skip band is no longer active.
The integral component of the PID controller is not held in the range of the skip speeds.
The skip band is passed through even for small system deviations and low controller gain factors. In so doing, the
controller integral time must be selected large enough so that no undesirable speed oscillations occur between the skip
band edges.
The influence of a minimum speed p1080 on the integration behavior can be reduced by raising the lower PID controller
limit to p1080 / p2000 * 100%.
For bit 06 = 1:
In r2349, bit 10 and bit 11 are not displayed when reaching internal limits (e.g. for OFF1/3).
