8.6.1.3 Servo Amplifier Module – SVM
The A25 is equipped with a Fanuc SVM to con-
trol the AC servo motor by using a PWM (Pulse
Width Modulation) inverter to regulate the DC
power converted by the PSM.
The SVM is a: Model No. SVM1-20, Type
A06B-6079-H102.
The SVM contains its own protection and error
detection functions. A 7-segment display, on
the front of the SVM, displays an alarm number
in the event of a SVM fault.
See
chapter 5
for details on the self-diagnostic
displays and
appendix A
for detail on SVM
alarms.

1. The rated output is guaranteed only at the rated input voltage. If the input
voltage varies, the rated output may not be obtained even when the variation
is within the allowable range.
2. The current limit (peak value) is a standard value. It varies by about ±10%
depending on the circuit constraints.
