output
Analog monitor
[FMA]
These terminals output monitor signals for analog DC voltage (-10
to +10 V).
Analog common

Transistor output 2
[Y1]
[Y2]
Both the SINK and SOURCE modes are supported.
(1) Various signals such as "Inverter running," "Frequency arrival
signal," and "Motor overload early warning" can be assigned to
terminals [Y1] and [Y2] by setting function code E20 and E21.
(2) The logic value (1/0) for ON/OFF of the terminals between
[Y1] or [Y2] and [CMY] can be switched. If the logic value for
ON between [Y1] or [Y2] and [CMY] is "1" in the normal logic
system,then OFF is "1" in the negative logic system and vice
versa.
