5.2.4 Setting the Energy Consumption and Resistance of the Dynamic Brake Resistor
5.2.4
Setting the Energy Consumption and Resistance of the
Dynamic Brake Resistor
If an External Dynamic Brake Resistor is connected, you must set Pn601 (Dynamic Brake
Resistor Allowable Energy Consumption) and Pn604 (Dynamic Brake Resistance).
*1.
SGD7S-210D to 370D SERVOPACKs require three Dynamic Brake Resistors. For this parameter setting, enter
the total value of resistor capacity of the three resistors.
*2.
SGD7S-210D to 370D SERVOPACKs require three Dynamic Brake Resistors. For this parameter setting, enter
the resistance of one Dynamic Brake Resistor multiplied by
.
Set Pn601 to the capacity of the Dynamic Brake Resistor that you calculated when selecting the
connected External Dynamic Brake Resistor or the capacity of the Resistor as reported by the
manufacturer.
Refer to the following section for details on the energy consumption of the Dynamic Brake
Resistor.
Energy Consumption of the Dynamic Brake Resistor
WARNING
If you connect an External Dynamic Brake Resistor, set Pn601 and Pn604 to suitable values.
Failure to set these parameters will cause an A.730 alarm (Dynamic Brake Overload) to be
detected incorrectly and can destroy the External Dynamic Brake Resistor, cause unintended
operation during an emergency stop, cause damage to the machine, and cause burning or
injury.
When you select an External Dynamic Brake Resistor, make sure that it has a suitable
energy consumption and resistance.
There is a risk of personal injury or fire.
CAUTION
Mount Dynamic Brake Resistors only on nonflammable materials. Do not mount them on or
near any flammable material.
There is a risk of fire.
