Name and Function
nternal speed command
3:
Used to set speed
3
of
internal speed commands.
nternal speed limit
3:
Used to set speed
3
of
internal speed limits.
kceleration time constant:
Used to set the acceleration time requlred to reach the rated speed
from zero speed in response to the analog speed command and
internal speed commands
1
to
3.
If
the preset command speed is
lower than the rated speed,
acceleration/deceleration
time
will
be shorter.
