(4) Speed synchronous control with encoder
(a) Set encoder as the main axis of speed sync. and execute positioning control by ratio of speed sync. that
consists of pulse speed from encoder, ratio of main axis and ratio of sub axis.
(b) This command is used in the case that executing thorough positioning manually.
(c) After executed speed sync. command, when the pulse string is inputted, speed sync. control starts.
(d) Operate regardless of the state of origin.
(e) The pulse inputted by encoder increase of decrease the position value of encoder.
(f) The direction of moving depends on encoder pulse input mode and ratio of speed sync,
■ Positioning in forward direction : Input pulse of A phase is ahead of B‟s
■ Positioning in reverse direction : Input pulse of B phase is ahead of A‟s
The position value increases when the input pulse
of phase A is ahead of B’s
The position value decreases when the input
pulse of phase B is ahead of A’s

. If it is
positive, operating direction will be forward direction of encoder. If it is negative, operating direction will be
reverse direction of encoder.
(g) Related parameter (Common Parameter)
Set parameter related to encoder on common parameter.
