3.6. Resolver Option [Archive]
N O T E :
This option is no longer available for purchase. This section is for legacy users.
The optional resolver provides six industry standard resolver channels that can be used as a feedback
device. The standard reference output frequency is 5 kHz (with factory configurations of 7.5 or 10 kHz). The
amplitude of this signal can be adjusted on a per-channel basis through the ResolverReferenceGain axis
parameter. The reference signal amplitude should be adjusted such that the level of the Sine and Cosine
resolver feedback signals is at 2 V RMS (or 2.83 V peak).
For correct operation of the resolver, the alignment between the resolver and motor must be known and
entered into the CommutationOffset axis parameter. This alignment can be determined by using the MSET
command. See the A3200 Help file for more information, including configuration of the axis parameters for an
axis with resolver feedback.
Resolver signals are provided to the user through one of two user interfaces, either the 9-pin “D” style
connectors above the motor connectors or through the standard J1-J6 feedback connectors as shown in
