Setting Torque Limits Using Parameters and an Analog Input
The
following block diagram shows the relationship between torque limit using parameters and torque limit
using
an analog input.
The
lowest torque limit set from among the following is enabled: Torque limit using parameters, torque limit
using
an analog input, 150% of Inverter rating (when set to CT), or 120% of Inverter rating (when set to VT)
set
in C6-01.
