Armature current
detection (polarized)
When the armature current command exceeds the armature current detection (with
polarity) (H-09) setting, the output is turned on.

Armature current
detection (absolute
value)
When the absolute value of armature current command exceeds the armature
current detection (absolute value) (H-10) setting, the output is turned on.

During power failure
When the input direct-current voltage becomes lower than the rated motor armature
voltage (A-03), the output is turned on. The output is turned off if rated motor
armature voltage (A-03) + 10 V or more is achieved for 200 V class, or rated motor
armature voltage (A-03) + 20 V or more is achieved for 400 V class.
Note that the output is turned off if the VFC66-Z power source is removed.

11 Overload
pre-alarm
When an overload condition described in the section of the Overload protection
setting (F-03) occurs and a value of the overload counter exceeds a level specified in
the Overload protection pre-alarm operation level setting (H-11), output is enabled.
A count value for activating overload protection (overtorque protection) shall be
100 %. (Suppose that the overload protection is set to be activated in a condition
where 150 % of current is output for 60 seconds and that 50 % is set to the Overload
protection pre-alarm operation level setting (H-11). In this case, when 150 % of
current is output for 30 seconds (i.e., 50 % of 60 seconds of the overload protection
activation time), output is enabled.)
