Diagnostic test DINT DINT Immediate Selects the specific test for the
motion module to run:
0 = motor/encoder hookup
test
1 = encoder hookup test
2 = encoder marker test
3=commutation test

Mnemonic Description
.EN (Enable) Bit 31 It is set when the rung makes a false-to-true transition and remains set until the servo message transaction is
completed and the rung goes false.
.DN (Done) Bit 29 It is set after the hookup test apply process has been successfully executed.
.ER (Error) Bit 28 It is set to indicate that the instruction detected an error, such as if you specified an unconfigured axis.
.IP (In Process) Bit 26 It is set on positive rung transition and cleared after the diagnostic test process is complete, or terminated by a
stop command, shutdown, or a servo fault.
.PC (Process Complete)Bit 27 It is set after the diagnostic test process has been successfully completed.
