3.8.3 Setting the Dynamic Brake Unit
Use the parameters shown in the tables here to make the settings for the following: the servomotor stopping
method when the servo is turned OFF, the output signals used to control the dynamic brake contactor, and the
capacity of the dynamic brake resistor in relation to whether or not a dynamic brake has been connected.
The servomotor stopping method when the servo is turned OFF is set with parameter Pn001.0.
When using a dynamic brake resistor from a company other than Yaskawa, set Pn00D.1 (second digit) to 0 or
1 in accordance with the following table depending if an NO or NC contact is used.
The dynamic brake resistor capacity is set with Pn601.
(1) Using a Yaskawa Dynamic Brake Unit
• Set Pn001 to n. 0.
• Not necessary to set Pn00D
• Set Pn601 to 0.
(2) Using a Dynamic Brake Resistors from Another Company
• Set Pn001 to n. 0.
• Set Pn00D to either n. 0D or n. 1 depending on your system.
• Set Pn601 to 20% of the resistor capacity of your dynamic brake.
(3) Not Using a Dynamic Brake
• Set Pn001 to n. 2.
• Not necessary to set Pn00D
• Set Pn601 to 0.

Enabled
Classification
Pn001
n. 0
[Factory
setting] Stops servomotor by applying DB (dynamic brake).
After restart Setup
n. 1 Stops servomotor by applying DB and then releases DB.
n. 2
Stops servomotor without applying DB by coasting to a
stop.
Parameter Meaning

Enabled
Classification
Pn00D
n. 0
[Factory
setting]
Enables the control of an NO contactor
(The dynamic brake is activated when current is sup-
plied to the contactor coil.)
After restart Setup
n. 1
Enables the control of an NC contactor
(The dynamic brake is activated when current is not
supplied to the contactor coil.)

If the setting of Pn601 is not correct, A.730 or A.731 (dynamic brake overloads) will not
be detected correctly and there is a risk of equipment damage or fire.
