3-5-3 Internal Speed Control Settings
H
Function
•
This function controls Servomotor speed using the speeds set in the parameters (No. 1, No. 2, and
No. 3 internal speed settings).
•
The internal speed is selected with control input terminals CN1-11 and CN1-12 (speed selection
commands 1 and 2). The direction of rotation is specified with CN1-15 (the rotation direction com-
mand).
•
When both speed selection commands 1 and 2 are OFF, the motor will decelerate to a stop in the
software start deceleration time (specified in Cn-23) and then go into servo lock status.
Depending on the parameter settings, it might be possible to perform position control in this status
using pulse-train inputs. (HA/LA/V/W Models)
H
Setup Parameter Settings
•
Set bit 2 of setup parameter number 2 (Cn-02) to “1.” When this bit is set to “1,” the internal speed
control settings function can be used and CN1-11, 12, and 15 have the following functions:
Control inputs CN1-11 and 12:
Speed selection commands 1 and 2 (SPD1 and SPD2)
. . . .
Control input CN1-15:
Rotation direction command (RDIR)
. . . . . . . . . . .

The following table shows the combinations of speeds and directions that can be selected with these
three control inputs.

Internal Speed Control Settings and Position Control (HA/LA/V/W Models)
•
When bit F of setup parameter number 1 (Cn-01) is set to “1,” the control mode will be “internal speed
control settings and position control.”
•
In this control mode, it is possible to perform speed control using the internal speed control settings
as well as position control using the pulse-train inputs.
•
When both SPD1 and SPD2 are OFF, the motor will be decelerated, the positioning completion out-
put will be output, and the servo will enter servo lock status. It will still be possible to receive pulse
command inputs in servo lock status.
Note Input pulse commands after the positioning completion output (INP) is turned ON. The Unit will
ignore any pulses input before the positioning completion output goes ON.
