Pulse Output Error Codes

1
The Profile Parameter Table starting at V2320 (default location) defines the profile. Certain
numbers will result in a error when the HSIO attempts to use the parameters to execute a
2
move profile. When an error occurs, the HSIO writes an error code in V2326.
Most errors can be corrected by rechecking the Profile Parameter Table values. The error is
3
automatically cleared at powerup and at Program-to-Run Mode transitions.

Troubleshooting Guide for HSIO Mode 30

11
If you're having trouble with Mode 30 operation, please study the following symptoms and
possible causes. The most common problems are listed below:
1

Symptom: The stepper motor does not rotate.

Possible causes:
1
1. Configuration – Verify that the HSIO actually generates pulses on outputs Y0 and Y1. Watch the
status LEDs for Y0 and Y1 when you start a motion profile. If the LEDs flicker on and off or are
steadily on, the configuration is probably correct.
14
2. Programming error – If there are no pulses on Y0 or Y1 you may have a programming error.
Check the contents of V2326 for an error code that may be generated when the PLC attempts to
A
do the move profile. Error code descriptions are given above.
3. Check target value – The profile will not pulse if the count value is equal to the target value
B (ex. count = 0, target= 0)
