H they are correctly wired to the controller;

 

H when the motor turns, the two square wave signals are 90

 

degrees out of phase. Also check the complement signals.

 

Ensure that the encoder lead uses shielded twisted pair cable

 

and that the shield is attached to the shield connection only at

 

the NextMove BXII end.

 

Verify that the NextMove BXII and drive are correctly grounded

 

to a common earth point.

 

 

6.2.3 Communication

If the problem is not listed below please contact Baldor Technical Support. An oscilloscope will be useful for many of the electrical tests described below.

Cannot detect NextMove BXII

Check that the NextMove BXII is powered and the serial

 

lead is properly connected.

 

 

Cannot communicate with the

Verify that WorkBench v5 is loaded and that

controller.

NextMove BXII is the currently selected controller.

6.2.4 Axis LED is red or Status LED shows a flashing symbol

If an axis LED is illuminated red and/or the Status display shows a flashing symbol, use the Error Log tool in WorkBench v5 to view a list of recent errors. Alternatively, type

PRINT AXISERROR and PRINT MISCERROR as separate commands in the WorkBench v5 Command window. Each of these commands will return an error code, a description of which can be found in the help file.

Press F1 and locate the AXISERROR and MISCERROR keywords. The Error Handling book contains topics listing the Status display indicators and basic error codes. Remember that many error codes are the sum of a bit pattern so may not be listed individually. For help on understanding bit pattern values, see the Bit pattern values topic in the Keywords book.
