Output with
specified
speed
Changing the
speed (frequency)
in one step
Outputs pulses at a
specified frequency.
SPED(885)
(Continuous)

“CW/CCW”
or “Pulse +
direction”
• Continuous

quency
Output with
specified
acceleration
and speed
Accelerating the
speed (frequency)
at a fixed rate
Outputs pulses and
changes the fre-
quency at a fixed
rate.
