Description
when output to motor is at the FA Threshold 1 (C042)
during accel, or at C043 during decel
when the output to motor is not at either the FA
Threshold 1 (C042) during accel or at C043 during
decel
when the over-torque feature is enabled and the motor
is generating excess torque
when the over-torque feature is disabled or the motor
is not generating excess torque
when the inverter input power has decreased below
the acceptable input voltage level
when the inverter input power is within rated range
when the inverter input power has decreased below
the acceptable input voltage level
when the inverter input power is within rated range
when the output torque exceeds level set for the
particular torque/frequency quadrant in effect during
operation
when the output torque is less than the level set for the
operating quadrant
when the inverter Run time exceeds the limit set by
Run/power-on warning time (B034)
when the inverter Run time is less than the limit set by
Run/power-on warning time (B034)
when the inverter plug-in time exceeds the set limit
when the inverter plug-in time is less than the limit
when the thermal limit for the motor is exceeded
when the thermal limit is not exceeded
when the inverter signals the external braking system
to release (open) its brake
when the inverter is not driving the motor, and needs
the external brake engaged
when the output current is less than the set releasing
current
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
when the encoder pulses of the motor has stopped
when motor rotation causes encoder pulses
when the velocity error exceeds the error threshold
defined for the encoder input
when the velocity error is less than the error threshold
defined for the encoder input
