*1 When "100" is set in Pr.52 Operation panel main monitor selection, set frequency is monitored during a stop and output frequency is monitored
during running.
*2 When position control is selected, the number of pulses is monitored when Pr.430 ≠ "9999".
*3 Write data is in hexadecimal, and only two digits are valid. (The upper two digits are ignored.)
*4 Setting from the remote register (RWw0) is also available.
*5 Turning OFF the power supply while clearing parameters with H5A5A or H55AA returns the communication parameter settings to the initial
settings.
*6 Reading or writing is available when the link parameter extended setting = "1 or 9".
*7 The gain frequency can be also written using Pr.125 (instruction code: H99) or Pr.126 (instruction code: H9A).
NOTE
• When a 32-bit parameter setting or monitored value is read and the read value exceeds HFFFF, the reply data will be HFFFF.
 Torque command / torque limit through CC-Link IE Field Network
communication
• Torque commands can be given or the torque can be limited via CC-Link IE Field Network under Real sensorless vector
control, Vector control, or PM sensorless vector control. The value is used to limit the torque during speed control or
position control, and to give a torque command during torque control. To limit the torque, set Pr.810 = "2". The torque
command / torque limit setting method can be selected using Pr.804 Torque command source selection. (Torque control
cannot be performed with a PM motor.)
• For setting the torque limit parameters, refer to
283.
• Set the torque command value or the torque limit value in RWw2. The RWw2 function is switched according to the Pr.804
and Pr.810 settings and the control mode.

All parameters return to initial values.
Whether to clear communication parameters or not can be selected according to the
data.

For details on whether or not to clear parameters, refer to
When clear is performed with H9696 or H9966, communication related parameter
settings also return to the initial values. When resuming the operation, set the
parameters again. Performing a clear will clear the instruction code HEC, HF3, and
HFF settings.
