FLA
Output
Multifunction programmable relay
contact output. Operation of the
protection function of the inverter
is detected in the default setting.
The contact across [FLA]-[FLC] is
closed and [FLB]-[FLC] is opened
during protection function operation. Maximum contact
capacity
• 250 Vac-2 A
(cos φ =1)
• 30 Vdc-2 A (at
resistive load)
• 250 Vac-1 A
(cos φ =0.4)
• 30 Vdc-1A
(L/R=7 ms)
Minimum contact
capacity
• 24 Vdc-5 mA
Life
• 100000 times

R1A
Output
Multifunction programmable relay
contact output. A low-speed signal
is output in the default setting.
R1C
R2A
Output
Multifunction programmable relay
contact output. It is not assigned in
the default setting. The function
can be set with <F134: Terminal
R2 function >.

Important
• With relay contact output, chattering (momentary ON/OFF of contact) is generated by external
factors of the vibration and the impact, etc. In particular, please set a filter of 10 ms or more, or
timer for measures when connecting it directly to the input unit of the programmable controller.
