3.9.5 Installation Standards
Observe the following installation standards when you use a Yaskawa dynamic brake unit. Provide at least 70
mm on each side of the unit and at least 200 mm at both the top and bottom of the unit to enable fan and natu-
ral convection cooling.
If you use a dynamic brake resistor from a company other than Yaskawa, follow the specifications of the
dynamic brake resistor when you install it.
3.9.6 Connections
(1) Using a Yaskawa Dynamic Brake Unit
A dynamic brake contactor is built into a Yaskawa dynamic brake unit.
The connections are shown in the following figure.
Note: The dynamic brake answer function (Pn515.2) cannot be used because there are no auxiliary contacts on the contac-
tor.
