• When the protective function of the inverter is activated, the MC1 signal is immediately turned OFF according to the Pr.248
setting. (The MC1 signal is turned OFF before the time set in Pr.254 has passed.)
When Pr.248 = "1", the MC1 signal is turned OFF when the protective function is activated due to any cause.
When Pr.248 = "2", the MC1 signal is turned OFF only when the protective function is activated due to an error resulted
from a failure in the inverter circuit or a wiring error (refer to the following table). (For the fault details, refer to

• To enable the self power management function for the separated converter type, enable the self power management
function also on the converter unit side. To activate the self power management function when a converter unit fault occurs,
connect the terminal to which the Y17 signal of the converter unit is assigned and the terminal to which X94 signal of the
inverter is assigned.

• To use the X94 signal, set "94" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function to an input terminal.
