5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
5-120
 Torque limiter (F40, F41, E16, E17) Data setting range: -300 to 300(%). 999 (Disable)
These function codes specify the operation level at which the torque limiters become activated, as the percentage
of the motor rated torque. Switching between motor 1 and 2 is possible using the control terminals (described later).

Torque limiter 1-2
Braking torque current limiter 1

Torque limiter 2-2
Braking torque current limiter 2
The setting range is the plus/minus range, but a plus value should be set. Operation will be performed
with an absolute value if a minus value is set.
Although the setting range of the torque is 300%, the torque limiter determined by the overload current of
the unit internally limits the torque current output. Therefore, the torque current output is automatically
limited at a value lower than 300 %, the maximum setting value.
 Analog torque limiter (E61 to E63, E66)
The torque limit value can be specified by analog inputs (voltage or current) through terminals [12], [V2], [C1] (C1
function), and [C1] (V3 function). Assign as follows with function codes E61, E62, E63, and E66.

8
Analog torque limit value B
Braking torque current limiter
If these terminals have been set up to have the same data, the operation priority is given in the following order: E61
> E62 > E63 > E66
 Torque limiter levels specified via communications link (S10, S11)
The torque limiter levels can be changed via the communications link. Communication dedicated codes S10, S11
interlock with the function codes F40, F41.
 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 E09. If no “TL2/TL1” is assigned, torque limiter levels 1-1
and 1-2 (F40 and F41) take effect by default.
