L8 Hardware Protection
The VS-616-G5 comes equipped with a number of built-in functions designed to protect the inverter
and its components from damage. This section describes the set-up of these functions.
When a Yaskawa dynamic braking resistor is used, protection against overheat is enabled with this func-
tion. The duty cycle of the braking resistor is monitored in software so that it does not exceed 3%.
If the duty cycle exceeds 3%, a DB overheat fault (RH) occurs, and the inverter coasts to stop.
