AC890PX AC Drive
2.1.5 External Brake Resistor (J)
The AC890PX is fitted with an internal resistor. Removing the internal brake resistor connections will disconnect the internal
braking resistor allowing the connection of an external brake resistor.
NOTE
It is possible to use both the internal and external brake resistors (wired as shown) but we recommend you contact
Parker Hannifin Manufacturing for advice.
Refer to Chapter 5: "Associated Equipment" - External Braking Resistors for help with using and selecting external brake
resistors.
The overload relay protects the internal brake resistor. The switch will require resetting to "ON" if the drive trips on BRAKE
SWITCH (the keypad display).
There are similar trips to protect the external brake resistor. Refer to Chapter 9: "Trips and Fault Finding".
