Automatic VC offset
If offset voltages in the analog circuits inside
and outside the servo amplifier cause the
servo motor to rotate slowly at VC (Analog
speed command) or VLA (Analog speed limit)
of 0 V, this function automatically makes zero-
adjustment of offset voltages.
When using this function, enable the function
in the following procedure. When it is
enabled, [Pr. PC37] value changes to the
automatically adjusted offset voltage.
1) Press the "SET" button once.
2) Set the number in the first digit to "1" with
"UP" button.
3) Press the "SET" button.
This function cannot be used if the input
voltage of VC or VLA is -0.4 V or less, or +0.4
V or more. (Note)
Note. Even if VC automatic offset is performed and 0 V is input, the servo motor may not completely stop due to an internal error. To
stop completely, turn off the ST1 or ST2.
