Configure the Brake Control Circuit
Follow these steps to configure brake control in KNX5100C software.
1. Double-click Function List > Digital IO/Jog Control
2. Check Edit DIO configurations.
3. From the Digital Output (DO) pull-down menu, choose Brake Control.
4. Verify that N.O. (normally open) is selected.
5. Uncheck Edit DIO configurations.
6. Click Settings>General Setting and configure the brake response engage
and disengage delay times based on the motor selected.
For motor brake coil-current and response time specifications for all
Allen-Bradley® motor families, see Kinetix Rotary Motion Specifications
Technical Data, publication KNX-TD001
.
Brake control is configurable in KNX5100C software. An active signal
releases the motor brake. Turn-on and turn-off delays are specified by
ID149 (P1.042) Disengage Delay Time and ID150 (P1.043) Engage Delay
Time parameter settings.
7. In Brake Time Settings, enter ID149 (P1.042) Disengage Delay Time and
ID150 (P1.043) Engage Delay Time parameter values.
IMPORTANT
Holding brakes that are available on Allen-Bradley rotary
motors are designed to hold a motor shaft at 0 rpm for up to
the rated brake-holding torque, not to stop the rotation of the
motor shaft, or to be used as a safety device.
You must command the servo drive to 0 rpm and engage the
brake only after verifying that the motor shaft is at 0 rpm.
