-RDP Expansion Board Ndrive HPe 10/20/30
Chapter 4: -RDP Expansion Board
The resolver to digital option (-RDP) provides up to two industry standard resolver or inductosyn channels
that can be used as a feedback device. The standard reference frequency output is 5 kHz, with factory
options for either 7.5 kHz or 10.0 kHz. The amplitude of this signal can be adjusted on both channels through
a single setting in the software. The -RDP can also be configured to generate encoder emulation signals.
For correct commutation of the motor, the alignment between the resolver and motor must be known. This
alignment can be determined by using the controller's software. Refer to the A3200 Help file for information
on configuring parameters for an axis with resolver feedback.
Channel 1 is on J401 and channel 2 is on J402. The -RDP option can supply up to 7 VRMS reference voltage
and requires 2 VRMS on the sine and cosine inputs.
D A N G E R : Always disconnect the Mains power connection before opening the Ndrive HPe
10/20/30 chassis.
