Description
Inverter is in Run Mode, motor running
When output to motor is at the standard set frequency F001
Turns ON when output to motor is at or above the FA
Threshold 1 (C042) during accel; turns OFF when motor
output goes below the threshold during decel
Output current is more than the set Threshold 1 for the
overload signal (set with C041)
PID error is more than the set threshold for the deviation
signal
Alarm condition has been met and not reset
Output to motor is at the FA Threshold 1 (C042) during accel,
or at C043 during decel
Over-torque feature is enabled and the motor is generating
excess torque
Inverter input power has decreased below the acceptable input
voltage level
Inverter input power has decreased below the acceptable input
voltage level
Output torque exceeds level set for the particular torque/
frequency quadrant in effect during operation
Inverter Run time exceeds the limit set by Run/power-on
warning time (B034)
Inverter plug-in time exceeds the set limit
Thermal limit for the motor is exceeded
ON when the inverter signals the external braking system to
release (open) its brake; OFF when the inverter is not driving
the motor and needs the external brake engaged
ON when the output current is less than the set releasing
current; OFF when the braking function is not in use, or when
the output current to the motor is correct and it is safe to
release the brake
Encoder pulses of the motor have stopped
Velocity error exceeds the error threshold defined for the
encoder input
Load position is at the target
ON when output to motor is at or above the FA threshold 2
(C045) during accel; OFF when the output to motor is below
the FA threshold 2 (C046) during decel
Output to motor is at the FA threshold 2 (C045) during accel
or at C046 during decel
