www.qinrm.com
In the ‘Availability’ column, a ‘F’, ‘C’ and ‘B’ indicate the command is available at ‘Factory Code’, ‘Customer Code’ and ‘Both codes’ respectively. Besides, a ‘C’, ‘P’ and ‘S’ denote the command is available only if the code is compiled in ‘Cert mode’, ‘Packwriter mode’ and ‘Servo Mode’ respectively.

Command Description Avail.
Bxx,yy SP-ZAP Test. Scheduled-Parameter WI-RRO Compensation to achieve ZAP (ZAP: Zero-Acceleration-Path)
Format: 4>Bxx[,yy]
Enter: 'B' Default . Show RROZAP status
'B0' Default. Show RROZAP status
'Bxx' SP-ZAP actions
xx= 1 -> Learn RROZAP table and compensate
from it. Clear table before learning
xx= 14 -> Master lock status. Toggles between normal RRO ZAP
operation and ‘freezing’ the status to always compensating from
the ram table.
xx= 2 -> Set "Comp" on and "FrmTbl" on.
xx= 3 -> Set "Comp" on and "FrmTbl" off.
xx= 4 -> Set "Comp" off and "FrmTbl" off.
xx= 5 -> Clear RROZAP table.
xx= 6 -> Same as "1" but with pure DACImage
xx= 7 -> Display RROZAP Table
Note: no “yy” when “xx” is 2,3,4,5,7.
“yy”, the number of learning iterations (default: 2). S
v Display RRO ZAP table
Display the RRO ZAP values in the ram table
Cxx,yyyy,aazzwww.qinrm.com/cindy Tracking Test.
Checks the current track for missing sector marks, bad gray codes, position errors greater than the test threshold, and position errors greater than the write threshold.
xx - Test threshold setting
yyyy - Position settle delay
zz - Loop count for each track
aa - Zap enable flag (if non-zero) F
Exx,yy,zz Display Active Log.
See /2 E for further detail. F
Fxx,yy,zz Seek Settle Adaptation Test ( All Zones)
xx - Head nos. Test on single head with head nos. entered. No entry/default will be tested
on all heads.
yy - Seek Length (Default = 10h, Max = 80h)
zz - Nos of average count. (Default = 20h)黎越
Note : Compensation count for each head after this test will be stored into system log and
upload during initial spin-up. F, S
Gxx Set Tracking/Seek Gain
xx - Tracking gain value to set (default is to display current gain). F
Hx Select Head x F
Kxx Servo Offset
xx - Offset (signed, 8-bit integer)黎越 F
