Attention
Consumable regenerative power (average) is 20% of the rated power of built-in
regenerative resistor.
In the case of forced air cooling, Cn012 can be set to twice the rated power of the resistor.
When connecting an external regenerative resistor, be sure to set Cn012 and Cn089 to
appropriate values. If the parameter setting is wrong, AL.061 alarm will be generated.
When selecting an external regenerative resistor, please make sure to maintain an
appropriate capacity and pay attention to the heat dissipation conditions. It is
recommended to use forced air cooling.
When the DC BUS voltage of a 200V driver exceeds 390V, and when the DC BUS voltage of
a 400V driver exceeds 780V, the regenerative resistor starts to consume voltage.
When using an external regenerative resistor at the normal rated load rate, when the
resistor temperature reaches 200°C~300°C, be sure to lower the rated value before using it.
For the characteristics of the resistor, please consult the manufacturer.
To ensure safety, it is recommended to use an external regenerative resistor with a
temperature control switch.
The built-in regenerative resistor in this device is able to consume the regenerative power
generated by acceleration/deceleration operation or vertical load. However, external regenerative
resistor is necessary when servo motor operation is driven by load side, otherwise this device will not
operate normally. When installing external regenerative resistor, please confirm the resistance is
identical to the one of the built-in resistor. If the user uses multiple parallelly connected small power
regenerative resistors to increase regenerative resistor power (W), please make sure the total resistance
is greater than the minimum tolerance listed in the above list.
External Regenerative Resistor Power Setting
When using external regenerative resistor, the power of the selected regenerative resistor must be
set correctly in Cn012.
