*1 Power with which the driver can be used without activating the built-in thermal
protector.
A built-in thermal fuse and a thermal protector are provided for safety.
The built-in thermal fuse blows depending on changes in heat dissipation
condition, operating temperature limit, power supply voltage or load.
Mount the regenerative resistor on a machine operating under aggressive
regenerating condition (high power supply voltage, large load inertia, shorter
deceleration time, etc.) and make sure that the surface temperature will not
exceed 100 °C.
Select and install a fan that maintains the surface temperature of
regenerative resistor at 100 °C or below during operation.
*2 If the wind speed is 1m / s by the fan.
