1 - LOGIC INPUTS
1.1 - "INHIBIT" INPUT
Activating the Inhibt input during the operation makes the axis decelerate. At the end of the deceleration, the
motor is automatically disabled.
The motor is enabled via the CANopen bus or via the Visual Drive Setup software, as the Inhibit input is
disabled.
Notes
:
- The amplifier inhibiting function is activated if the "Inhibit" input is disconnected from the +24V potential.
- The Deceleration parameter can be parameter set via the CANopen bus.
1.2 - "LIMIT SWITCH" INPUTS
The "Limit switch" inputs are inputs for a detection sensor that allows to stop the motor with maximum
deceleration. The purpose of both limit switches, when they are mounted at the right place on the axis stroke, is to
protect the mechanics in case of uncontrolled movements.
The limit switches are only defined according to the motor hardware rotation. They are independent from the
"rotation/counting direction" selection.
For checking the wiring of the limit switch inputs:
- move the motor in one direction,
- activate the limit switch placed in the rotation direction (artificially, if necessary),
- check then the motor stopping; if the motor goes on moving, reverse the wiring of the limit switch inputs.
Notes
:
- When activating a limit switch input, the motor is stopped with maximum deceleration.
- The limit switch inputs are activated if disconnected from the +24V potential.
1.3 - "LOW SPEED" INPUT
When this input is activated, the amplifier switches to protected mode if the motor speed is exceeding the critical
"Low speed" threshold.
Note
:
- The Low speed parameter cannot be higher than 33 % of the Max. speed parameter.
- The Low speed input is activated if disconnected from the +24V potential.
- The Low speed threshold can be parameter set via the CANopen bus.
1.4 - "INDEX" INPUT
In Homing mode, the Index input is used for a homing on the axis.
2 - BRAKE CONTROL
The CD1-k amplifier has got a control for the operation of a "powerless" brake.
The brake control is enabled (relay open) or disabled (relay closed) according to the amplifier status (enabled or
disabled).
