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. In level 3, the PID controller source enable can also come from the digital
inputs in settings 722.0 to 722.2 for DIN1 to DIN3 or from any other BiCo source.
The minimum and maximum motor frequencies (P1080 and P1082) as well as the skip frequencies (P1091 to P1094)
remain active on the variable speed drive output. However, enabling skip frequencies with PID control can produce
instabilities.

Fixed PID setpoint 1 through 15
Defines fixed PID setpoint 1
Unit: % Min: -200.00 Def: See Note Below Max: 200.00
Level 3
Defines fixed PID setpoint 1. In addition, you can set any of the digital input parameters to fixed PID setpoint via the
digital inputs (P0701 - P0706).
There are three selection modes for the PID fixed setpoint:
1. Direct selection (P0701=15 or P0702=15, etc)
In this mode of operation, 1 digital input selects one PID fixed setpoint.
2. Direct selection with ON command (P0701=16 or P0702=16, etc.)
Description as for 1), except that this type of selection issues an ON command concurrent with any setpoint selection.
3. Binary Coded Decimal selection with ON command (P0701 - P0706=17)
Using this method to select the PID Fixed Setpoint allows you to choose up to 16 different PID setpoints. The
setpoints are selected according to the following table:

Dependency:
P2000=1 required in user access level 2 to enable setpoint source.
In mode 1 (above):
ON command required to start motor (enable pulses).
In mode 2 (above):
If inputs programmed to PID fixed setpoint and selected together, the selected setpoints are summed.
You may mix different types of frequencies; however, remember that they will be summed if selected together.
P2201=100 % corresponds to 4000 hex.
Default fixed PID setpoint values are as follows:
Fixed PID Default Fixed PID Default Fixed PID Default
1 0.00 6 50.00 11 100.00
2 10.00 7 60.00 12 110.00
