4.2.2 Speed Reference Output Mode
„ Overview
This mode is used to rotate the motor at the desired speed.
A speed reference is output to the servo driver according to the specified speed reference, lin-
ear acceleration/deceleration time constant, and filter time constant.
The acceleration/deceleration time can be set as desired.
S-curve acceleration/deceleration can be easily performed by the user program (one com-
mand).
The speed reference output mode can also be used for a general-purpose D/A converter. In
this case, set the linear acceleration/deceleration time constant and the filter time constant to
“0.”
The speed reference output mode can be used only with SVA-01A and SVA-02A Modules. It cannot be
used with SVB-01 or PO-01 Module.
„ Details
Use the following procedure to perform operation in the speed reference output mode.
1. Set the motion fixed parameters according to the user’s machine.
IMPORTANT
1. Set the motion fixed parameters.
2. Set the motion setting parameters.
3. Set the speed reference output mode (NCON).
4. Set the RUN command (RUN) to ON.
