Note: A retry Spin-up operation may be attempted during the Start up process.

Table 4.2 Start and Stop time
Item Typical unit
Start 25 Note 1 s
Stop 25 Note 2 s
Note 1. Start time means that the time of becoming ready, after DC power has been
applied in the case of Enable Auto Start mode, or after Start Unit command
(immed=0) has accepted in other case. If internal retry is executed during the
Start-up operation, the Start time may exceed typical value. It is recommended to
have 60 seconds for the Start time. In the case of a spindle start-up failure, the
time of an internal retry operation is 130 seconds maximum.
Note 2. Beginning of stop time is basically decided by +12v DC power off.
In case of +5v DC power off only, stop time is 65sec(typ).
Do not move the drive until motor stop completely.
Stop time means that the time to stop the spindle rotation, after DC power has
been shut off, or after stop operation has started.
