Amplification Output A2
Calculation Example:
Switching Condition Out-
put D1
The analog output A2 (terminal X2.19) outputs the current speed of the
servo systems.
Parameter CP.20 defines the amplification of the analog output signal.

Rated speed of the servo system: 3000 rpm
At 1000 rpm a measurement shall be taken at analog output A2 +10 V.
