<Notes>
For safety, a thermal fuse is built in the optional external regenerative discharge
resistor. Wiring to the internal thermal fuse may break depending on the applicable
heat radiating conditions, operating temperature range, supply voltage and load fluc-
tuation.
Be sure to assemble the amplifier with the machine and check the operating limit so
that the surface temperature of the regenerative discharge resistor may be 100Åé or
lower on poor conditions likely to cause generation of regenerative discharge resis-
tance (such as high supply voltage, large load inertia and short deceleration time).
For amplifier types, see pages 10
and 11.
