Configurable I/O Application Functions
Preset speeds
2, 4 or 8 speeds can be preset, requiring 1, 2, or 3 logic inputs respectively.
The following order of assignments must be observed : PS2 (LIx), then PS4 (LIy), then PS8 (LIz).
To unassign the logic inputs, the following order must be observed : PS8 (LIz), then PS4 (LIy), then PS2 (LIx).
Reference switching
Switching of two references (AI1 reference and AI2 reference) by logic input command.
This function automatically assigns AI2 to speed reference 2.
Connection diagram
Open contact, reference = AI2
Closed contact, reference = AI1
Freewheel stop
Causes the motor to stop using the resistive torque only. The motor power supply is cut.
A freewheel stop is obtained when the logic input opens (state 0).
DC injection stop
An injection stop is obtained when the logic input closes (state 1).
Fast stop
Braked stop with the deceleration ramp time reduced by a reduction factor dCF which appears in the drive
menu.
A fast stop is obtained when the logic input opens (state 0).
