Start and Stop Time
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.
