(i)
On the terminal block TB3, remove the wires U, V,
and W which are connected to the motor.
(ii) In the same manner as Section 2.4.4, to open CON101
to 103,
remove the SF-CA card from the hinge panel.
(iii) In accordance with the following criteria, check the
electric continuity of each terminal and determine
whether the transistor module is good or bad.
(Note) Even if part of the transistor module is defec-
tive,
replace the entire amplifier with a new
one.
In addition, if the transistor module
should be replaced,
to prevent the transistors
from being damaged by your static electricity,
ground yourself and replace it by referencing
Section 2.7.
