mand in MECHATROLINK-III communications.
This section provides the operating procedure for speed/torque (pressure) table operation.
1.
Set Pn440 to n.
1 (Enable pressure feedback control).
2.
Send the SV_ON (Servo ON) command.
3.
Other station monitoring is set and checked only when you use the FT41.

If bit 28 is ON, the VELCTRL command is interpreted as a speed/torque (pressure)
table operation command.

Start speed/torque (pressure) table
operation.
If bit 28 is OFF, only VELCTRL commands are acknowledged.
Do not use the CMD_PAUSE (Pause) or CMD_CANCEL (Cancel) commands during speed/torque
(pressure) table operation. The send timing will affect behavior and may prevent normal control
operations.
