Use Of Stall Setting (Output When Operation Is Stopped) - Mitsubishi LE-40MTB-E Instruction Manual

5.2 Use of stall setting (output when operation is stopped)

Stall output is a constant torque given during the automatic control to the machine while it is stationary. At
this stage, the feedback control does not take place. This torque is the initial torque for the machine to start
with in the automatic control.
• When Run/stop signal MC1 is turned off to stop the material, the stall memory retains the control output
values used immediately before the stop. The system resumes the operation using the memorized
control output values to stabilize the tension in the material.
The stall memory function is a part of the basic functions, no need to be specially set.
• When changing materials, for example, the stall memory is reset to the output values appropriate to the
initial material diameter. These output values are called the stall setting value.
The system uses an EEPROM memory to keep the stall memory values even when the power supply is
turned off. No reset operation takes place even when the power supply is turned off or automatic or manual
modes switching is performed.
