P2200[0...2] BI: Enable PID controller - 0 U, T - CDS U32 /
Bin
2
Allows user to enable / disable the PID controller. Setting to 1 enables the PID closed-loop controller.
Dependency: Setting 1 automatically disables normal ramp times set in P1120 and P1121 and the normal frequency
setpoints.
Following an OFF1 or OFF3 command, however, the inverter frequency will ramp down to zero using the
ramp time set in P1121 (P1135 for OFF3).
Notice: The minimum and maximum motor frequencies (P1080 and P1082) as well as the skip frequencies (P1091
to P1094) remain active on the inverter output.
However, enabling skip frequencies with PID control can produce instabilities.
Note: The PID setpoint source is selected using P2253.
The PID setpoint and the PID feedback signal are interpreted as [%] values (not [Hz]).
The output of the PID controller is displayed as [%] and then normalized into [Hz] through P2000
(reference frequency) when PID is enabled.
The reverse command is not active when PID is active.
Attention: P2200 and P2803 are locked parameter against each other. PID and FFB of the same data set
cannot be active at same time.
P2201[0...2] Fixed PID setpoint 1 [%] -200.00 -
200.00
10.00 U, T - DDS Float 2
Defines fixed PID setpoint 1. There are 2 types of fixed frequencies:
1. Direct selection (P2216 = 1):
– In this mode of operation 1 Fixed Frequency selector (P2220...P2223) selects 1 fixed frequency.
– If several inputs are active together, the selected frequencies are summed. E.g.: PID-FF1 + PID-
FF2 + PID-FF3 + PID-FF4.
2. Binary coded selection (P2216 = 2):
– Up to 16 different fixed frequency values can be selected using this method.
Dependency: P2200 = 1 required in user access level 2 to enable setpoint source.
Note: You may mix different types of frequencies; however, remember that they will be summed if selected
together.
P2201 = 100 % corresponds to 4000 hex.
