5.2. Settings According to Host Controller
This section describes the procedure for connecting an FSP Amplifier to a host
controller, including the procedure for setting related parameters.
5.2.1. Speed Reference
Input the speed reference using the input signal: Speed Reference Input.
Since this signal has various uses, set the optimal reference input for the
system created.

The above inputs are used for speed control (analog reference). (Pn000.1 =
0, 4, 9, or A.) Always wire for normal speed control.
Refer to 7.1.6 Operation in Monitor Mode.
The motor speed is controlled
in proportion to the input voltage between V-REF and SG.

The slope is set in Pn300.
„ Setting Examples
Pn300 = 600: This setting means that 6 V is equivalent to the rated motor
speed.
