5.3 Description of Function Codes
5-90
■ Torque limiters 1 (Driving, Braking), and 2 (Driving, Braking) (F40, F41, E16 and E17)
• Data setting range: 0 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.
Function code Name
F40 Torque limiter 1 (Driving)
F41 Torque limiter 1 (Braking)
E16 Torque limiter 2 (Driving)
E17 Torque limiter 2 (Braking)
The torque limiter determined depending on the overload current actually 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)
The torque limit value can be specified by analog inputs (voltage or current) through terminals [12], [C1] (C1
function), and [C1] (V2 function). Assign by Extension function selection function codes E61, E62, E63 (Terminal
[12], [C1] (C1 function), [C1] (V2 function) as follows.
E61, E62, E63 data Function Description
7 Analog torque limiter A
Used when analog inputs are used as torque limiters.
Input modes: 200% / 10 V or 20 mA
8 Analog torque limiter B
If these terminals have been set up to have the same data, the operation priority is given in the following order: E61
> E62 > E63
Refer to E59 on how to use terminals [C1] (C1 function) and [C1] (V2 function).
■ Torque limiter levels specified via communications link (S10, S11)
The torque limiter levels can be changed via the communications link. Function codes S10 and S11 exclusively
reserved for the communications link correspond to function codes F40 and F41.
