Explanation
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, P2-37 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 P2-25.
Normally Closed, Falling Edge, Open momentarily to FAST STOP the drive using Fast Stop
Ramp Time P2-25.
Normally Closed, External Trip input. When the input opens momentarily, the drive
trips showing E-Trip or F-PTC depending on P2-33 setting. See section Motor Thermistor
Connection on page 33 for further information.
Analog Input 1, signal format selected using P2-30.
Analog Input 2, signal format selected using P2-33.
Analog Input 1 provides the speed reference.
Analog Input 2 provides the speed reference.
Speed reference from the selected preset speed.
Preset speeds P2-01 – P2-08 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 Open / Master depending on
P1-12 setting).
Input is Normally Open, Close momentarily to activate the function.
Input is Normally Closed, Open momentarily to activate the function.
During deceleration and stopping, Deceleration Ramp 1 (P1-04) is used.
During deceleration and stopping, Deceleration Ramp 2 (P8-11) is used (Requires
Advanced Parameter Access, see section Parameter Set Overview on page 45.
