Pr.18
Torque limit setting value
With this function, the torque generated by the motor is limited to within the set
range.
* The torque exceeding the limit is reduced to the specified torque limit. Set the
maximum torque value necessary for the control in the range between 1 and
500%.
Usage conditions
Limits for pulse train output type
(a) A drive unit that can issue a torque limit command with the analog voltage is
required.
(b) The D/A conversion module and the D/A conversion module and drive unit
must be wired.
(c) The set "
Pr.18 Torque limit setting value" is set in the buffer memory " Md.45
Torque limit stored value", so transmit that "
Md.45 Torque limit stored value"
to the D/A conversion module with the sequence program.
