Map the additional position command drive signals as described in the
section of this appendix.
Position Command Drive Signals
This section describes additional signals that are used with position command drives. You can
use these signals with your drive if you map the signal functionality to an available digital input
or digital output using software. Refer to the
NI SoftMotion Module
book of the
LabVIEW Help
for more information about mapping digital inputs and digital outputs. Refer to Chapter 3,
, for information about other NI 9512 module signals.
The following inputs are driven from the drive to provide system status to the module.
•
Servo Alarm/Drive Fault
—Disables the drive in case of a drive error. The module does
not generate step and direction outputs when the alarm input is active. The alarm signal is
inactive during normal operation.
•
In-Position
—Indicates that the drive has completed the move and has reached the target
position.
•
Servo Ready/Drive Ready
—Indicates that the drive is ready or enabled.
The following signal is driven from the module to the position command drive:
•
Alarm Clear
—Clears the alarm or fault outputs on the drive.
Note
The Alarm Clear functionality is not mappable in software. Refer to the
NI SoftMotion LabVIEW Help
for information about implementing this functionality
using an available digital output.
