OFF1 and ramp down time

Hi

I am sure I am disabling OFF1 Bit to the sinamics S120  drive. OFF2 and OFF3 remains healthy . However the drive does not ramp down according to ramp down time set on P1121 (20s).  It stops within 2 sec. What could be the problem . Please assist.

Thank u in advance

Hello,

Have you checked the status of internal/control word in r0898. Bit 0 should be 0 & bits 1,2,3,4,5,6 must be 1. Please check the status when applying OFF1. How much is the value in P1122?

Please refer r0046 (sheet attached here with for ready reference). OFF1, OFF2, OFF3, RFG signal status msut follow as per the signals mentioned.

HTH.

What is p1082 and what was your speed setpoint?

Thanks 

My problem is solved . Just had to trend r898 and r2090 bits as it was suggested. Found that OFF2 bit comes on and off  and it took priority over Off1.
