Sync Pulse
A sync pulse output is available for each channel and is located on the P4 connector
(See Table 10). The functionality of the sync pulse depends on whether the channel is
in static mode (not rotating) or dynamic mode (rotating).
In static mode, a pulse will occur when an angle is written to the channel.
In dynamic mode, a pulse will occur when the output crosses 0°.
The sync pulse width is 100 µSec.
4.2 On-board Reference Sine Oscillator
The on-board oscillator may be used to take the place of an external drive oscillator
for the excitation signal. This oscillator is available in two options, see Table 5 for
details. The oscillator frequency and voltage are programmable through software. The
oscillator output is transformer isolated. To use the on-board reference oscillator for a
specific channel(s), the reference output signals OSC_RH_OUT and OSC_RL_OUT
must be connected to the specific channel(s)’ RH_IN and RL_IN on the connector P3.
The oscillator has a status output which is constantly monitored in an internal register
that is accessible through software. This status is dependent on both the oscillator’s
enable/disable status and if the oscillator is in an over-temperature/over-current
condition.
For example, if the oscillator is enabled and goes into an over-current/over-
temperature condition, the oscillator will go inactive. The oscillator will become active
again once the fault condition no longer exists.
See the
Get_D2rsRefStatus()
function for details.
