(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.

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.
