Drive Enable Output

The +/- Axis Enable is a signal from the 1394 system module that is
used to control a DPDT relay in the 1394-DIM. This enable output is
a normally open, unpowered (dry) signal.

Analog Output

The analog output is an isolated signal provided by the 1394-DIM and
has a range of ± 10V. The signal is either a torque or velocity
command, depending on the configuration of the remote drive. The
command is processed by the Bulletin 1394 System Module through a
12-bit Digital-Analog Converter (DAC). An output offset of ± 80 mV
can be compensated to 0V through software configuration.
