Each mode setting

(1) 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.

*1. Set at factory shipment.
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 IDD 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.
Start timing of the spindle motor
Starting of the motor is controlled with the
START/STOP UNIT command.
The motor is started immediately after the
power supply is turned on or after the
microcode is downloaded.
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 Chapter 3 of the SCSI Logical Interface Specifications for details of the START/STOP
UNIT command.
