(2) Using a Dynamic Brake Resistor from Another Company
 Using NO Contacts for the Dynamic Brake Contactor
∗ The above figure is for using a dynamic brake contactor with NO contacts. The dynamic brake answer signal (a signal
from NO auxiliary contacts) is input to CN1-45. To indicate an error if the input signal to CN1-45 turns OFF (open)
while the dynamic brake is activated, the Pn515 parameter in the SERVOPACK must be set to n.E. If the
dynamic brake answer signal is not used, Pn515 is set to n.8 (default setting).
Note 1. If you assign more than one signal to the same input circuit, OR logic will be used and any of the input signals
will cause the circuit to operate. This may result in unexpected operation.
2. The maximum current for DB24 and DBON is 300 mA.
