ACS880 Status word bit 8
Hi,
I have replaced ACS800 with ACS880. For start command is used DI1 and for freq reference FB A ref1. When DI1 state is 1, drive is operating and output freq changes as FB A ref1. When DO1 state is 0, output freq is zero and FB A ref1 remains to max, i.e. 60Hz.
With ACS880 installed, when DO1 state is 0 (not operational drive, output is 0 Hz and FB A ref1 is 60Hz) Main Status Word (ABB Drives profile) bit 8 become value 0 (actual value outside tolerance). This was not happening with ACS800.
I tried with changing para 46.22, but still the same, bit 8 value goes to 0.
Is there any way not to get MS word bit 8 = 0 ?
Thank you.

Bit 8 in main status word (MSW) of ACS800 and ACS880 is the same and doesn't depend of digital outputs (DO).
Bit 8 — AT_SETPOINT:
Value = 1 — OPERATING. Actual value equals reference value (= is within tolerance limits);
Value = 0 — Actual value differs from reference value (= is outside tolerance limits).
