2.2 Positioning control by multi-step point setting

2.2.1 Settings of main parameters
When A510=1, input of the target position by multi-step point setting is enabled.
To switch points, use preset speed commands 1 to 3 (digital input terminal functions 10/11, 12/13, 14, 15).
The following are parameters necessary for positioning control by multi-step point setting.
• Set A510=1.
• Set A544 to A596 according to the number of steps of the positioning point.
For each multi-step point, the target position (example: A544, A545), frequency at the time of position control
(example: Sr1), acceleration/deceleration time until the frequency with a position command is reached
(example: A547, A548), function (example: A546) can be set with parameters. For the parameter corresponding
to each point, see the table below. For how to set, refer to 2.2.1.1 and 2.2.1.2.

Remarks
• Set F146 and F147=2 to input the
speed feedback signal to the S4 and
S5 terminals.
• Set the relevant parameter to 1 to
input the position command signal
to S4 or S5 terminal.
Generally, set a value approx.
between 3 Hz to 5 Hz.
Auto-tuning is performed immediately
after operation start.
