(H) Protective Function Parameter - Mitsubishi FR-A800 Instruction Manual

(H) Protective function parameter

5.10
(H) Protective function parameter
Purpose
To protect the motor from
overheating
To set the overheat protection
characteristics for the motor
To decelerate and stop when the
motor thermal protection is
activated
To extend the life of the cooling fan
To detect ground fault at start
To vary the operating level of the
undervoltage protective function
To initiate an inverter protective
function
To disable the I/O phase loss
protective function
To restart using the retry function
when the protective function is
activated
To set the upper and lower limits of
the output frequency
To prevent the motor from
overspeeding under torque control
To avoid overdriving the motor
during speed control
To operate by avoiding resonance
points
To limit the output current so that
the inverter protective function
does not activate
To limit the torque during speed
control
To shut off the output during
acceleration
To shut off the output when
deceleration is not possible
