4.3.1Start and Stop Time

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.

Caution

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.
