●
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 alarm details, refer to page 6-9.)
●
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 manage-
ment function when a converter unit fault occurs, connect the terminal to which Y17 signal of the
converter unit is assigned and the terminal to which X94 signal of the inverter is assigned.
