8. Control Terminal Functions
For standard applications and operation, the basic control of the drive and functions of all drive input terminals can be configured
using just two parameters, P1-12 and P1-13. P1-12 is used to define the source of all control commands and the primary speed
reference source. P1-13 then allows fast selection of Analog and Digital Input functions based on a selection table.
8.1. Control Source Selection
8.1.1. P1-12 Function
P1-12 is used to select the main control source of the drive and the main speed reference according to the following table:

When keypad mode is selected, the default operation of the drive
requires the keypad Start & Stop buttons are used to control the drive.
This can be changed using P-31 to allow the drive to be started from
Digital Input 1 directly.

PID Output
Enable / Disable control of the drive is through the drive control
terminal strip.
Output frequency is set by the output of the PI Controller. This mode
must be used for pressure regulation.

Control of the drive operation is through a fieldbus option module
mounted in the drive option slot. If no option module is fitted, control is
through the Modbus RTU interface.
Digital Input 1 must be closed to allow operation.

From Master
Optidrive P2 provides an inbuilt Master / Slave function. A single
drive acts as the Master, and connected Slave drives will mimic the
starting and stopping, along with the following the output frequency,
with any scaling applied.
Digital Input 1 must be closed to allow operation.

Control of the drive operation is through the BACnet Interface.
Digital Input 1 must be closed to allow operation.
The P2 Solar Pump Drive will operate the MPPT control in the background irrespective of the control mode selected as shown above.
8.1.2. Overview
Optidrive P2 uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key parameters
which determine the input functions and drive behaviour:
P1-12 – Selects the main drive control source and determines how the output frequency of the drive is primarily controlled.
P1-13 – Assigns the Macro function to the analog and digital inputs.
Additional parameters can then be used to further adapt the settings, e.g.
P2-30 – Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA.
P2-33 – Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA.
P2-36 – Determines whether the drive should automatically start following a power on if the Enable Input is present.
P2-37 – When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable
command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive.
The diagrams below provide an overview of the functions of each terminal macro function, and a simplified connection diagram for
each.
