4.4. –RDP Resolver Input
The optional resolver input provides two industry standard resolver or Inductosyn
channels, which may each be used as a feedback device. Each may be separately
configured for resolver or inductosyn input, as shown in Table 4-21. The standard
reference output frequency is 10 kHz, optionally it may be configured as 5 or 7.5 kHz at
the factory.
The Sine and Cosine feedback signals should be adjusted for 2 volts RMS (2.8 volts
Peak) via the CfgFbkRDGain axis parameter. The resolver can be physically aligned to
the motor, by using the MSET CNC programming command. This physical relationship
may also be defined via the CfgMotOffsetAng axis parameter. All of which is described
in Section 4.4.1. See the Nview help for information on configuring the axis parameters
for an axis with resolver feedback.
The J403 external power connector is not available at this time.
