Parameter Settings for the Dynamic Brake Circuit

You must set the following parameters to create the dynamic brake circuit.
Allocation of /DBON (Dynamic Brake Operation Request Output)
signal
Allocation of /DBANS (Dynamic Brake Answer Input) signal
Selection of motor stopping method
Energy consumption of the Dynamic Brake Resistor
Resistance of Dynamic Brake Resistor
/DBON (Dynamic Brake Operation Request Output) Signal
The /DBON signal is the trigger signal for executing dynamic braking.
Create the sequence so that the Magnetic Contactor in the dynamic brake circuit is excited
when the /DBON signal is turned ON.
Important
The /DBON signal is required to execute dynamic braking on SGD7S-210D to 370D SERVO-
PACKs. On SERVOPACKs other than SGD7S-210D to 370D, the /DBON signal cannot be allo-
cated.

/DBANS (Dynamic Brake Answer Input) Signal
The /DBANS signal is used to check the operating status of the Magnetic Contactor in the
dynamic brake circuit.

Always configure the parameter settings for the /DBANS and /DBON signals when using the
External Dynamic Brake Resistor.

Item to Set
1. If you allocate more than one signal to the same output connector pin, a logical OR of the sig-
nals is output. Set the /DBON signal so that it is not allocated to the same terminal as another
output signal.
2. If the /DBON signal is allocated to the same terminal as another output signal, the A.F32
(Dynamic Brake Operation Request Output Signal Setting Error) alarm will occur to prevent
unexpected operation.
The A.F32 alarm will also occur when an output signal is allocated with the following objects to
the same terminal as the /DBON signal.
• Digital outputs (60FEh)
• Objects related to ZONE outputs (2752h, 2753h)
• Objects related to output signals (250Eh to 2510h, 2514h)
