Auto restart

The power stage inhibit will automatically be released upon clearing the cause of the inhibit.

Status Reporting

Status is available to the user in several ways.

Communication

In response to the Tell Status command (TS) the DCB sends a coded message describing the status of the amplifier.

In addition, the host may request certain information at any time. This consists of the state of the system (GN?, ZR?, PL?, KI?), the state of the local inputs (TI), the torque level (TT), the current motor position (TP), the current motor velocity (TV) and the reason for a stop condition (TC).

Refer to the DCB Software Manual for further details.

Hardware signal

Motion complete signal

This output will go to high when motion is complete.

Inhibit output

Whenever the amplifier is inhibited, this open collector output goes to low. When using Elmo's mother boards a potential free relay replaces the open collector output.

4-digit display

Whenever a fault occurs, a fault message will be displayed for easy visual information. See chapter 9.1 for a summary of all amplifier's fault indications.

Define origin modes

The origin is that location at which the absolute position of the motor equals zero. This special location may be defined in two ways. First, the user may send a command (DH) which defines the current motor position to be the origin. The alternate method is to request the DCB to perform the homing sequence by commanding HM.
