7. Analog and Digital Input Macro Configurations
7.1. Overview
TECDrive 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.
7.2. Macro Functions Guide Key
STOP / RUN Latched input, Close to Run, Open to Stop
Forward Rotation /Reverse Rotation Selects the direction of motor operation
AI1 REF Analog Input 1 is the selected speed reference
P-xx REF Speed setpoint 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
˄-FAST STOP (P-24)-˄ When both inputs are active simultaneously, the drive stops using Fast Stop Ramp Time P-24
E-TRIP External Trip input, which must be Normally Closed. When the input opens, the drive trips showing
or depending on P-47 setting
(NO) Normally Open Contact, Momentarily Close to Start
(NC) Normally Closed Contact, momentary Open to Stop
Fire Mode Activates Fire Mode, see section 7.7 Fire Mode
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 signal via
the fieldbus interface
INC SPD Normally Open, Close the input to Increase the motor speed
DEC SPD Normally Open, Close input to Decrease motor speed
KPD REF Keypad Speed Reference selected
FB REF Selected speed reference from Fieldbus (Modbus RTU / CAN Open / Master depending on P-12 setting)
