Chap. 5 FUNCTION CODES
Torque limiter 1-1, 1-2, 2-1 and 2-2 (F40, F41, E16 and 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.
Function code Name Torque limit feature
F40 Torque limiter 1-1 Driving torque current limiter 1
F41 Torque limiter 1-2 Braking torque current limiter 1
E16 Torque limiter 2-1 Driving torque current limiter 2
E17 Torque limiter 2-2 Braking torque current limiter 2
Although the data setting range for F40, F41, E16, and E17 is from positive to negative values (–300% to
+300%), specify positive values in practice. If a negative value is specified, the inverter interprets it as an
absolute value.
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 limit values (E61 to E63)
The torque limit values can be specified by analog inputs through terminals [12], [C1], and [V2] (voltage or current).
Set E61, E62, and E63 (Terminal [12] Extended Function, Terminal [C1] Extended Function, and Terminal [V2]
Extended Function) as listed below.
Data for E61, E62, or E63 Function Description
7 Analog torque limit value A
8 Analog torque limit value B
Use the analog input as the torque limit value specified by
function code data (= 7 or 8).
Input specifications: 200% / 10 V or 20 mA
If the same setting is made for different terminals, the priority order is E61>E62>E63.
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 respond to function codes F40 and 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 TL2/TL1 as the terminal function, set any of E01 through E07 to "14." If no TL2/TL1 is assigned, torque
limiter levels 1-1 and 1-2 (F40 and F41) take effect by default.
