)
When using the built-in brake resistor, brake unit
·
Set "0" in Pr. 30.
The Pr. 70 setting is made invalid.
At this time, the regenerative brake duty is as follows:
M4500-001 to 101.......................2%

)
When using the external high-duty brake resistor
·
Set "1" in Pr. 30.
·
Set "10%" in Pr. 70.
Note: 1. The Pr. 70 setting is invalid for the inverter of 025 or more.
2. Pr. 70 "regenerative brake duty" indicates the %ED of the built-in brake transistor operation. Its
setting should not be higher than the setting of the brake resistor used. Otherwise, the brake
resistor can overheat.
3. 7.5K does not have the built-in brake resistor.
WARNING
The Pr. 70 setting must not exceed the setting of the brake resistor used. Otherwise,
the brake resistor can overheat.
