RMC70/150 and RMCTools User Manual
Resolvers are commercially available in many varieties with different specifications. The
primary specifications of interest as applied to the RMC are:
•
Frequency
The frequency of the Reference Signal driving the primary winding.
•
Voltage
The specified voltage of the Reference Signal driving the primary winding.
•
Output Voltage
The output voltage from the secondary windings or the transformation ratio between
primary and secondary windings.
The RMC Resolver module is designed to work with only a subset of all resolver types
available. The Resolver Module topic lists the range of values compatible with the
standard RMC Resolver module. In addition, a wider range of resolvers can be used by
modifying components on the interface card module or by using external reference
generators to drive the primary winding. Contact Delta for more details.
Setting Up the Resolver Module
1. Wire the resolver according to the RMC150 Resolver Wiring topic.
2. Set the following parameters:
•
•
•
3. Scale the axis. Typically, resolvers will use Rotary Scaling. Notice that one revolution
of the resolver will always consist of 65,536 counts on the RMC, regardless of the
resolver resolution parameter.

3.13.1. Controller Image Upload/Download
The controller image refers to the entire RMC project as it is stored in the RMC. Only
RMCTools can create the controller project (image) and download it to the RMC. However, a
PLC or PC can read the RMC image via Ethernet or USB, store it, and later download it to the
RMC. This feature is only supported on the RMC75E and RMC150E. The controller image
upload/download is an advanced feature and is not necessary in most applications.
The controller image can only be downloaded to an RMC that matches the hardware
configuration of the image. Downloading and applying a controller image typically takes
between 3 and 20 seconds, depending on the options selected.
Uses for storing and downloading the controller image include:
1. Know the exact contents of the RMC
Allowing the PLC to control the contents of the RMC removes any problems due to
tampering with an RMC. For example, when a machine starts up, the PLC may write
the image to the RMC so that it knows the RMC has the correct project.
2. Replace an RMC without using RMCTools
If an RMC needs to be replaced, RMCTools is not needed if the PLC or RMCLink will
download the controller image. This greatly simplifies machine repair when an
