deepak.samal05 Posts: 65 Rating: (0)	hello sir, i am having a simple doubt regarding some parameters in MM440 While configuring in the remote mode,P0700 is 2. What is coast to standstill (OFF2) and immediate ramp down(OFF3) and how to use those two parameters i tried to give p0701 as 1(start) and p0702 as 3(coast to standstill( and p0703 as 4(immediate ramp down) but drive is not running in those condition.so how to use th\ese parameters and practical application of these two parameters

Give P1000 = whatever speed setpoint source you want. If this still does not work, perhaps the digital inputs were already set to BICO in which case you need to factory reset the drive to return them to normal digital operation. Regards, Graeme

Means if you are setting OFF2 for DI 2 then DI2 should be always ON You can check status of DI using Parameter r722
