FUNCTION CODES
Chap 5
■ 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 by 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.
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 (undesirable oscillation of the system). Avoid concurrent
activation of these limiters.
Under vector control without speed sensor nor pole position sensor
When a PMSM is driven under vector control without speed sensor nor pole position sensor, the torque limiters are
used like as IM driven under vector control without speed sensor.
When switching control target motor and control method with the function code F42, the Factory defaults
are
also switched.
The factory default for PMSM is 200%.
