Fixed PI setpoint 1
Defines the Fixed PI Setpoint 1
In user access level 2 you will need to set P2200 to enable the setpoint source. In addition
you can set any of the digital input parameters to fixed PI setpoint via the digital inputs
(P0701 – P0703.)
There are three modes of selection for the PI fixed setpoint.
1 Direct selection (P0701 = 15 or P0702 = 15, etc)
In this mode of operation 1 digital input selects 1 fixed PI fixed setpoint.
If several inputs are programmed to PI fixed setpoint and selected together, the selected
setpoints are summed.
To start the motor (enable pulses), an ON command is needed either from the keypad or
from the digital inputs or USS in this mode.
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 coincident
with any setpoint selection.
Note
You may mix different types of fixed frequencies; remember, however, they will be summed
if selected together.
3 Binary Coded Decimal selection P0701 – P0703 = 17
Using this PI fixed point selection method it is possible to choose up to 7 different PI
setpoints. The setpoints are selected according to the following table:
