Control Terminal Connections
8.2. Overview
Optidrive Compact 2 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.
8.3. Macro Function Guide
Latched Input, Open the contact to STOP the drive
Latched input, Close the contact to Start, the drive will operate as long as the input is maintained
Latched Input, selects the direction of motor rotation FORWARD
Latched Input, selects the direction of motor rotation REVERSE
Latched Input, Close to Run in the FORWARD direction, Open to STOP
Latched Input, Close to Run in the REVERSE direction, Open to STOP
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.
Normally Open, Rising Edge, Close momentarily to START the drive (NC STOP Input must be maintained)
Simultaneously applying both inputs momentarily will START the drive (NC STOP Input must be maintained)
Normally Closed, Falling Edge, Open momentarily to STOP the drive
Normally Open, Rising Edge, Close momentarily to START the drive in the forward direction (NC STOP Input must be
maintained)
Normally Open, Rising Edge, Close momentarily to START the drive in the reverse direction (NC STOP Input must be
maintained)
When both inputs are momentarily active simultaneously, the drive stops using Fast Stop Ramp Time P-24
Normally Closed, Falling Edge, Open momentarily to FAST STOP the drive using Fast Stop Ramp Time P-24
Normally Closed, External Trip input. This input may be used for:
o External Trip function
o Motor thermistor connection (see section 6.7 Motor Thermistor Connection)
When the input opens momentarily, the drive trips showing External Fault or Thermistor Over Temperature
depending on P-47 setting.
Activates Fire Mode, see section 8.5.1 Fire Mode
Analog Input 1, signal format selected using P-16
Analog Input 2, signal format selected using P-47
Analog Input 1 provides the speed reference
Analog Input 2 provides the speed reference
Speed reference from the selected preset speed
Preset speeds P-20 – P-23 are used for the speed reference, selected according to other digital input status
PI Control Speed Reference
Analog Input used to provide a Feedback signal to the internal PI controller
Keypad Speed Reference selected
Normally Open, Close the input to Increase the motor speed
Normally Open, Close input to Decrease motor speed
Selected speed reference from Fieldbus (Modbus RTU / CAN / Master depending on P-12 setting)
Input is Normally Open, Close momentarily to activate the function
Input is Normally Closed, Open momentarily to activate the function
