Manufacturer wording — SERVO OVC(total) (%d)
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC SRVO-216 (“SERVO OVC(total)”): There is a lack of DSP chip for the axis, which is set in the $AXISORDER system variable. First check: Check whether the number of the DSP is enough on the DSP board related to the axis number of $SCR_GRP[].$AXISORDER[].

Description
There is a lack of DSP chip for the axis, which is set in the $AXISORDER system variable.
Remedy
Check whether the number of the DSP is enough on the DSP board related to the axis number of $SCR_GRP[].$AXISORDER[]. Change the DSP board that has enough DSP. Or change the setting of $AXISORDER.
Field diagnosis
The sum of the currents of the six axes in the robot connection cable exceeds the allowable limit.
What to check
- Slow down the most demanding motions, check the cycle rate and load against rated values, check the cabinet input voltage.
- Note: Different from SRVO-046 (one axis): here it is the sum, so a program, not a motor.
