4.1 Fault with power unit PM0--600 series “1” and “2”
If, while an external axis is running, a second or third external axis is switched off and on again
(with the aid of the individual axis switch--off function), an error message “Overcurrent axis
X” is displayed at the time of switching on.
The error is caused by the common supply voltage for the driver stages of all external axes
which temporarily drops to zero due to the current surge of an axis being switched on.
This error only takes place when the individual axis switch--off is activated and when two or
more axes have to be switched individually.
Remedial action:
In the case of two or more external axes with individual axis switch--off, the series “3”
PM0--600 power unit must be used. This applies only to PM0 with Art. nos. 69--000--700 and
00--100--015.
