NOTE
1 The "maximum output at acceleration" value is
provided only to aid in the selection of a power
supply module; this is not a guaranteed value.
2 When a spindle motor with a maximum output of
5kW or more is used, the resistance of the
regenerative discharge unit must be 8Ω. If a
regenerative discharge unit with a resistance of 16Ω
is used for a spindle motor with a maximum output
of 5 kW or more , a regeneration excess alarm
(alarm No. 08) may be generated in the PSMR
when the spindle is decelerated.
