The following table specifies the braking options for 400V class L100 inverters and the

braking torque for each option. Use BRD–EZ2 braking unit for 400V class inverters.

Note 1:

A = Average braking torque from 60 Hz to 3 Hz.

Note 2:

B = Average braking torque from 120 Hz to 3 Hz.

Note 3:

BRD maximum duty cycle = 10%, where T

≤

0.1 sec.

Note 4:

BRD maximum continuous On time T

≤

10 sec.
