3. SIGNALS AND WIRING
(b) Speed selection 1 (SP1) and speed command value
At the initial condition, the speed command values for the internal speed command 0 and 1 can be
selected using the speed selection 1 (SP1).

By making the speed selection 2 (SP2) and the speed selection 3 (SP3) usable by setting of parameter
No.PD02 to PD14, the speed command values for the internal speed commands 0 to 7 can be selected.

The speed may be changed during rotation. In this case, the values set in parameters No. PC01 and
PC02 are used for acceleration/deceleration.
When the speed has been specified under any internal speed command, it does not vary due to the
ambient temperature.
POINT
The servo-on (SON) can be set to turn on automatically by parameter No.
PD01 (input signal automatic ON selection 1).
The forward rotation stroke end (LSP) and the reverse rotation stroke end
(LSN) switches as follows:
Assigned to the external input signals: depends on the value set in
parameter No. PD01.
Not assigned to the external input signals: automatically turns on regardless
of the value set in parameter No. PD01.
If parameter No. PC23 (function selection C-2) is set to "
value), the servo motor is servo-locked regardless of the deceleration time
constant when the zero speed (ZSP) turns on.
