Inrush Current Prevention Resistor Overheat Detection Protection
(Alarm Code: 0h6) (Bit 5)
On 0.1 to 15 kW inverters, when overheating of the inrush current prevention resistor inside the inver-
ter is detected when the main circuit power is turned ON and started, the overheat protection function
(alarm 0h6) is activated. When startup is slow due to the main circuit power being a variable power
supply device, the overheat protection function is sometimes activated. In this case, protection can be
disabled.
Braking transistor error detection (dba) (Bit 6)
An error in the built-in braking transistor is detected, the inverter is topped, and the alarm dba is dis-
played. To disable alarm generation without using the braking transistor, set this bit to “0.”
