eal4Labview - Interpolation halted on wait

Hello!
I`m using eal4Labview in my Labview application to control 5 drives with HCS01.
I attached a part of my vi to control a drive. Should work simple...
- Power on drive
- check if error occured
- clear error if error occured
- move to absolute position
- wait until movement finished
- power off drive

I often get error 1172 "Interpolation halted on wait" from the ealMotionWait.vi (see attachment).
Anybody an idea why this happens and what I can do to solve this issue?

Best regards, Markus

Hello Markus,

I would double check if in case of your exception S-0-0437 Bit3 is true.

In case it is this means the drive internal position command (P-0-0434) has not yet reached the target position of your move absolute vi and P-0-0048 is zero. This can i.e. happen if S-0-0259 is 0.

So you should check your move absolute vi if there was a velocity setpoint (!=0) commanded.  Please also check if the mentioned parameter is changed by an analog input or by another channel.

If this is not your solution please forward a par file in case of exception.

Best regards
