AC reactor for PSM with small capacity SVM or SPM
When the servo amplifier module (SVM) or the spindle amplifier module (SPM) of
the following table is connected only the number of connection in the table to the
alpha i series power supply module (PSM) that is power supply regeneration type,
AC reactor "A81L-0001-0170" should be used.
Note 1)
Since power supply regeneration continues and does not stop according to power
supply conditions (Low power supply impedance, Large unbalance of power supply
voltage) when standard AC reactor is used, power supply current may become
excessive.
Note 2)
In the case of the alpha i series power supply module (PSMR) that is resistance
regeneration type or beta i series servo amplifier, this phenomenon is not
generated.
Note 3)
Instead of using the alpha i series power supply module (PSM), beta i series servo
amplifier is recommended for downsizing.
