Hello: I use sscan Record to drive 2 positioners synchronously. When the 2 positioners’ scan mode are all TABLE, only
positioner 1 can be scanned, it can move position by position as P1PA
specified. positioner2 will move to 0, then stop. if I set positioner 2 to
LINEAR mode, these 2 can both be scanned, 2 motors can move position by
position synchronously. I have specified P1PA and P2PA by caput ?a
IOC:scan1.P1PA 10 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 caput ?a
IOC:scan1.P2PA 10 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 Could you tell me why positioner 2 can’t move
position by position like position 1 does when both in TABLE mode? Is there any
problem with my db file? The db file is like this: record(motor,
"$(P)m1"){ field(SCAN,
"Passive") field(DESC," field(DTYP,"OMS
MAXv") field(DIR,"Pos") field(VELO,"10000") field(VBAS,"4000") field(ACCL,"0.2") field(BDST,"0") field(OUT,"#C0S0@") field(MRES,"8") field(PREC,"0") field(EGU,"um") field(DHLM,"100000") field(DLLM,"-100000") field(VMAX,"15000") field(INIT,"AF") } record(motor,
