Group C0: Torque control and parameter limitation
Selection of control the speed /
torque
It is used to select the inverter control mode: speed control or torque control.
V 800 provides S-terminals with two torque-related functions, "Torque control is disabled"
(function 29) and switching between "Speed control / torque control" (function 46). Both
S-terminals must be used together with C0.00 to perform the speed / torque control
switching. If function 46 (switching speed control / torque control) is assigned to the S-
terminal, it is OFF, the control mode is determined by C0.00. If the S terminal allocated
with function 46 is ON, the control mode is to reverse the value of C0-00.
However, if the torque control function is disabled, the inverter is fixed for operation in
the speed control mode.
Torque control source settings
Digital setting of torque
control
Parameter C0.01 is used for "Torque Control Source Settings". There are a total of 8
Torque Controllers. The torque setting is the relative value, the value of 100.0%
corresponds to the nominal torque. The adjustment range is from -200.0% to 200.0%,
which means that the maximum torque of the inverter is twice the nominal torque of the
motor.
The torque setting uses 1-7, i.e.. communication interface, analog input and pulse input.
The data format is -100.00% to 100.00%. 100% corresponds to C0.03.
