3.4.5 Control Signals for Direct Indication Mode
This is an operation mode to indicate directly with values for the target position, positioning
width, speed, acceleration/deceleration and pressing current.
Set a value to each input and output data register. Set to the parameters when using the zone
signals.
The main functions of ERC3 capable to control in this mode are as described in the following
