External Regenerative Resistor
Remarks
Thermal fuse is installed for safety. Compose the circuit so that the power will
be turned off when the thermostat is activated. The thermal fuse may blow
due to heat dissipating condition, working temperature, supply voltage or load
fluctuation.
Make it sure that the surface temperature of the resistor may not exceed 100˚C at
the worst running conditions with the machine, which brings large regeneration
(such case as high supply voltage, load inertia is large or deceleration time is
short) Install a fan for a forced cooling if necessary.
Caution
Regenerative resistor gets very hot.
Take preventive measures for fire and burns.
Avoid the installation near inflammable
objects, and easily accessible place by hand.
