5.3 Description of Function Codes
5-88
■
Switching torque limiters
The torque limiters can be switched by the function code setting and the terminal command “TL2/TL1” (Select
torque limiter level 2/1) assigned to any of the digital input terminals. To assign the Torque limiter 2/Torque limiter 1,
“TL2/TL1” set Data = 14 in function codes from E01 to E05. If no “TL2/TL1” is assigned, torque limiter levels 1-1
and 1-2 (F40 and F41) take effect by default.

Torque limiter (Braking) (Frequency rising limit for braking) (H76) Data setting range: 0.0 to 500.0 (Hz)
H76 specifies the rising limit of the frequency in limiting torque for braking. The Factory defaults are 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.
