Torque Change Function - Mitsubishi Electric RD77MS2 User Manual

Torque change function

The "torque change function" is used to change the torque limit value during torque limiting.
The torque limit value at the control start is the value set in the "[Pr.17] Torque limit setting value" or "[Cd.101] Torque output
setting value".
The following two change methods in the torque change function.
Torque change function
Forward/reverse torque limit value
same setting
Forward/reverse torque limit value
individual setting
*1 Forward torque limit value: The limit value to the generated torque during CW regeneration at the CCW driving of the servo motor.
Reverse torque limit value: The limit value to the generated torque during CCW regeneration at the CW driving of the servo motor.
Set previously "same setting" or "individual setting" of the forward/reverse torque limit value in "[Cd.112] Torque change
function switching request". Set the new torque value (forward new torque value/reverse new torque value) in the axis control
data ([Cd.22] or [Cd.113]) shown below.

individual setting
Details
The forward torque limit value and reverse torque limit value are changed to the same value by the new torque value.
(Use this method when they need not be separately set.)
The forward torque limit value and reverse torque limit value are individually changed respectively by the forward new
torque value and reverse new torque value.
Setting items
