SCREWS
Unscrew only two “
A
” screws to remove the case and
therefore to set FC, CO and J3 jumpers.
Fig. 6:
For A-NDC 94, A-NDC 96 and A-NDC96.S models, remove the case to set FC and CO jumpers (see Fig. 6).

APPLICATION NOTES:
•
A type ia a standard current profile (used in NDC series).
•
B type current profile performs higher motor movement smoothness with lower acoustical noise and vibrations.
Smoothing effect of B type depends on resolution setting: the more resolution is low, the more smoothing is effective.
•
C type current profile performs higher motor torque.
•
D type current profile is not recommended.

DRIVE STATUS BY LED
LED HV green:
ON
= supply voltage value in working range.
OFF
= no supply voltage or supply voltage out of working range
LED FAU red:
ON
= drive set in no working state by one of the following protection:
a
– Thermal protection, if LED TER is ON
b
- Max or Min voltage when LED HV is OFF
c
- Short circuit or wrong connection at motor output when LED HV is ON
OFF
= drive active provided that LED HV is ON
LED TER yellow:
ON
= drive set in no working state by thermal protection.
OFF
= drive active provided that LED HV is ON.
