Overview
Optidrive E3 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:-
P-12
– Selects the main drive control source and determines how the output frequency of the drive is primarily controlled.
P-15
– Assigns the Macro function to the analog and digital inputs.
Additional parameters can then be used to further adapt the settings, e.g.
P-16
– Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA
P-30
– Determines whether the drive should automatically start following a power on if the Enable Input is present
P-31
– 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.
P-47
– Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA
The diagrams below provide an overview of the functions of each terminal macro function, and a simplified connection diagram for each.

Macro Function Guide
Function
Explanation
STOP
Latched Input, Open the contact to STOP the drive
RUN
Latched input, Close the contact to Start, the drive will operate as long as the input is maintained
FWD
Latched Input, selects the direction of motor rotation FORWARD
REV
Latched Input, selects the direction of motor rotation REVERSE
RUN FWD
Latched Input, Close to Run in the FORWARD direction, Open to STOP
RUN REV
Latched Input, Close to Run in the REVERSE direction, Open to STOP
ENABLE
Hardware Enable Input.
In Keypad Mode, P-31 determines whether the drive immediately starts, or the keypad start key must be pressed.
In other modes, this input must be present before the start command is applied via the fieldbus interface.
START
Normally Open, Rising Edge, Close momentarily to START the drive (NC STOP Input must be maintained)
˄- START -˄
Simultaneously applying both inputs momentarily will START the drive (NC STOP Input must be maintained)
STOP
Normally Closed, Falling Edge, Open momentarily to STOP the drive
START
FWD
Normally Open, Rising Edge, Close momentarily to START the drive in the forward direction (NC STOP Input must be
maintained)
START
REV
Normally Open, Rising Edge, Close momentarily to START the drive in the reverse direction (NC STOP Input must be
maintained)
˄-FAST STOP (P-24)-˄
When both inputs are momentarily active simultaneously, the drive stops using Fast Stop Ramp Time P-24
FAST STOP
(P-24)
Normally Closed, Falling Edge, Open momentarily to FAST STOP the drive using Fast Stop Ramp Time P-24
E-TRIP
Normally Closed, External Trip input. When the input opens momentarily, the drive trips showing
or
depending on P-47 setting
Fire Mode
Activates Fire Mode, see section 2.7.1 Fire Mode
Analog Input AI1
Analog Input 1, signal format selected using P-16
Analog Input AI2
Analog Input 2, signal format selected using P-47
AI1 REF
Analog Input 1 provides the speed reference
AI2 REF
Analog Input 2 provides the speed reference
P-xx REF
Speed reference from the selected preset speed
PR-REF
Preset speeds P-20 – P-23 are used for the speed reference, selected according to other digital input status
PI-REF
PI Control Speed Reference
PI FB
Analog Input used to provide a Feedback signal to the internal PI controller
KPD REF
Keypad Speed Reference selected
INC SPD
Normally Open, Close the input to Increase the motor speed
DEC SPD
Normally Open, Close input to Decrease motor speed
FB REF
Selected speed reference from Fieldbus (Modbus RTU / CAN Open / Master depending on P-12 setting)
(NO)
Input is Normally Open, Close momentarily to activate the function
(NC)
Input is Normally Closed, Open momentarily to activate the function
