1: Torque limit mixed mode (No polarity)
If |Tref|<PL, Tpl = |Tref|
If |Tref|>PL, Tpl = PL
If |Tref|<NL, Tnl = |Tref|
If |Tref|>NL, Tnl = NL
2: Torque limit mixed mode (Positive)
If 0<Tref<PL, Tpl = Tref
If Tref>PL, Tpl = PL
If Tref<0, Tpl,Tnl = 0
3: Torque limit mixed mode (Negative)
If Tref>0, Tpl,Tnl = 0
If -NL<Tref<0, Tnl = -Tref
If Tref<-NL, Tnl = NL
This parameter can allow the users to set two different kinds of torque limit command sources
when limiting torque. We call it is “Torque Limit Mixed Mode”.
The torque limit function is activated by parameter P1-02 or via digital input TRQLM, TLLM or
TRLM.
If the users use TRQLM or P1-02 to activate torque limit function, the torque limit command
source can be analog input or internal parameters (P1-12 to P1-14) depending on which way
you use to activate torque limit function. At this time, the limit of PL and NL in the figure below
are specified as the torque limit that determined by the torque limit command source.
If the users use TLLM or TRLM to activate torque limit function, the torque limit command source
can be parameter P1-12 (NL) or P1-13 (PL).
