7 Setting and Confirming CDBR Braking Unit Operation
Braking Activation Voltage Rotary Switch (S3)
■
Set the braking activation voltage rotary switch S3 to match the power supply of the main
circuit. Refer to Table 13
voltage.
Note: Rotary switch S3 does not typically require adjustment.
NOTICE: Consider the amount of voltage fluctuation in the DC bus when changing rotary switch S3 setting
values. Setting the braking activation voltage to a low value and energizing the drive may activate the CDBR
and overheat the braking resistor.
NOTICE: Firmly click the switch into the proper position. A switch stuck between positions may cause the
CDBR to operate incorrectly.
