r2273
PI error
--
--
%
Displays PI scaled error (difference) signal between setpoint and feedback signals in [%].
Note:
r2273 = 100% corresponds to 4000 hex
P2280
PI proportion gain
0.000 - 65.000
3.000
--
Allows user to set proportion gain for PI controller.
Note:
Default value depends on connection macro selected. See Table 7-11 for details
P2285
PI integral time
0.000 - 60.000
0.000
s
Sets integral time constant for PI controller.
Note:
Default value depends on connection macro selected. See Table 7-11 for details
P2291
PI output upper limit
-200.00 - 200.00
100.00
%
Sets upper limit for PI controller output in [%].
Dependency:
If F max (P1082) is greater than P2000 (reference frequency), either P2000 or P2291 (PI output upper limit)
must be changed to achieve F max.
Note:
P2291 = 100% corresponds to 4,000 hex (as defined by P2000 (reference frequency)).
P2292
PI output lower limit
-200.00 - 200.00
0.00
%
Sets lower limit fort he PI controller output in [%].
Dependency:
A negative value allows bipolar operation of PI controller.
Note:
P2292 = 100% corresponds to 4,000 hex.
P2293
Ramp-up/-down time of PI limit
0.00 - 100.00
1.00
s
Sets maximum ramp rate on output of PI.
When PI is enabled, the output limits are ramped up from 0% to 100%. Limits prevent large step changes
appearing on the output of the PI when the inverter is started. Once the limits have been reached, the PI
controller output is instantaneous.
These ramp times are used whenever a RUN command is issued.
Note:
If an OFF1 or OFF 3 are issued, the inverter output frequency ramps down as set in P1121 (ramp-down
time) or P1135 (OFF3 ramp-down time).
Default value depends on connection mode code selected. See Table 7-11 for details
r2294
Actual PI output
--
--
%
Displays PI output in [%]
Note:
r2294 = 100% corresponds to 4000 hex
