Setting terminator power supply 

 

Refer to Table 5.2 for controlling the supply of power from the drive to the SCSI terminator 
power source (TERMPOW).  

 

For information on NP model, refer to Figures 5.2 and 5.3.

For NC model, the function of the terminator power supply setting is not supported. 

(2) 

Motor start mode 

 

Set how to control the starting of the HDD spindle motor according to Table 5.3.  This setting 
only determines the operation mode when the power supply is turned on or the microcode is 
downloaded.  In both modes, stopping or restarting the spindle motor can be controlled by 
specifying the START/STOP UNIT command.

(*1) 

The motor is started after the elapse 

of a delay time that is based on the 

SCSI ID.  The delay time is provided 

immediately after the power supply is 

turned on or after the microprogram 

is downloaded.

*1. Set at factory shipment. 
*2. For NP model, delay starting of spindle motor is supported by the CHANGE  DEFINITION 

command only. 

*3. To set the setting terminals on NC models to short, apply voltage ranging between-0.3 V and 0.8 

V to the setting terminals externally.  To set the setting terminals on NC models to open, apply 

voltage ranging between 2.0 V and 5.5 V to the setting terminals from an external source. 

 

Refer to Subsection 3.1.10 “START/STOP UNIT (1B)” of the SCSI Logical Interface 
Specifications for details of the START/STOP UNIT command.
