In this mode, it can switch between the speed mode and torque mode with the control
mode switching terminal (MCH). The corresponding relationships of the terminal status
and modes are:
MCH
Control mode
0 Speed
mode
1 Torque
mode
0
:
OFF (the terminal is disconnected with COM-);
1
:
ON (the terminal is connected with COM-).
The switching between the speed mode and the torque mode can be performed at any
moment. The switch process is shown in the figure below:

5: Position/torque mode
In this mode, you can switch between the position mode and torque mode with the
control mode switching terminal (MCH). The corresponding relationships of the
terminal status and modes are:
MCH
Control mode
0 Position
mode
1 Torque
mode
0
:
OFF (the terminal is disconnected with COM-);
1
:
ON (the terminal is connected with COM-).
For safety, after changing the MCH terminal input status, the switching between
position mode and torque mode can be performed only when the motor speed
becomes lower than the value of zero speed range (PC.05). The switching process is
shown in the figure below:
