■ 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 for details on rotary switch S3 position and braking activation
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.
