The standard parameters are stored in ROM. If the pa-
rameter list attached to the machine is lost or when an
accident occurs and no parameter can be set, perform
the setting of standard parameters.
Also when a ROM is replaced with different maximum
speed applied to different motor model, perform the fol-
lowing procedure.
However, since the standard parameters are set to
each motor, some parameters must be modified by the
parameter list according to the machine’s unique char-
acteristics.
