2.2 List of parameters
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The setting is only effective if a skip band is no longer active.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).
