p2200[0...2] BI: Enable PID controller / Enab. PID ctrl
Access level: 2
Quick comm. NO
Can be changed: U, T
Min
-
Description: 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).
When Standard Telegram 350 and PROFIBUS selected (P0700 = 6, P0922 = 350), parameter cannot be changed.
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 fre-
quency) when PID is enabled.
The reverse command is not active whilst PID is active.
Attention: p2200 and p2803 are locked parameter against each other. PID and FFB of the same dataset cannot be
active at same time.
p2201[0...2] Fixed PID setpoint 1 / Fixed PID setp. 1
Access level: 2
Quick comm. NO
Can be changed: U, T
Min
-200.00 [%]
Description: 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.
2. Binary coded selection (P2216 = 2):
- Up to 16 different fixed frequency values can be selected using this method.
- The fixed frequencies are selected according to FP3310.
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.
p2202[0...2] Fixed PID setpoint 2 / Fixed PID setp. 2
Access level: 2
Quick comm. NO
Can be changed: U, T
Min
-200.00 [%]
Description: Defines Fixed PID Setpoint 2
Note: See P2201 (Fixed PID Setpoint 1).
