Section L: Protection Parameters

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.

Setting Range: 0 to 100°C

Factory Default: 100°C

Sets the heatsink temperature level for protection against overheat (OH).
