5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
Torque limiter (Braking) (Frequency rising limit for braking) (H76) Data setting range: 0.0 to 599.0 (Hz)
H76 specifies the rising limit of the frequency in limiting torque for braking. The factory default is 5.0 Hz. If the
increasing frequency during braking reaches the limit value, the torque limiters no longer function, resulting in an
overvoltage trip. Such a problem may be avoided by increasing the setting value of H76.
The torque limiter and current limiter are very similar in function. If both are activated concurrently, they
may conflict with each other and cause hunting. Avoid concurrent activation of these limiters.
Torque limiter (Operating conditions selection) (H73)
It is possible to set whether to enable or disable torque limiting while the motor is accelerating or
decelerating, or while it is running at constant speed.
During acceleration/deceleration
During constant speed running
