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.

*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.
