This article describes an easy method to verify CMD port input signal proper functionality on VSD-E/XE drives.
Note: This testing method works only for following inputs:
- Opto-in 1
- Opto-in 2
- Analog in 1 (as digital input)
- Analog in 2 (as digital input)
Opto-in 3-4 can't be tested this way because these are shared with serial traffic and would interfere with GDtool connection. However, working GDtool connection proves that inputs 3-4 are working because connection wouldn't be possible otherwise.
Setup
Connect drive to GDtool and follow the instructions below.
- Configure "User bit"
- Select input to be tested from configuration dialog
- Click Ok
- Click Set
Then go to Device status tab
- 4. Monitor "User configured input" status bit and see if it changes as you toggle the selected input signal on CMD port. Green means that drive reads input value as logic 1 (or 0 if invert option selected).
Note: this method doesn't verify fast toggling signals. Status page update interval is 1-2 seconds so shorter than 2 second pulses may not change status color.
