Gem6K Hardware Installation Guide
Aligning the Resolver – GV6K Servos (optional)
Resolvers on Compumotor motors are aligned at the factory. Ordinarily, no further
alignment is required. However, you may wish to align the resolver if you suspect
the resolver is misaligned, or if you are using a non-Compumotor motor.
A Note About Resolver Speed
Resolver speed describes the relationship between resolver electrical revolutions
and shaft mechanical revolutions. For example, if one resolver electrical revolu-
tion is equal to one shaft mechanical revolution, the resolver is a “single speed” or
“one speed” resolver. If two electrical revolutions equal one mechanical revolu-
tion, the resolver is a “two speed” resolver.
The following alignment procedures assume you have configured the drive with an
accurate resolver speed value. For Compumotor motors, resolver speed is loaded
from the motor configuration file.
Resolver Alignment Procedures
There are three methods to align the resolver:
• Method 1 – Enter a known resolver offset angle.
• Method 2 – Find an unknown resolver offset angle, and store it in the drive’s
nonvolatile memory.
• Method 3 – Loosen the resolver cleats and rotate the housing while monitoring
offset angle. Secure the housing when the angle is zero degrees.
Details for these methods are given below.
Method 1 – Entering a Known Offset Angle
1. Disconnect the load from the motor shaft. The shaft should be free to rotate.
2. Issue an SRSET command; include the desired offset angle. For example, entering
SRSET10 automatically sets the offset angle to 10 resolver electrical degrees.
WARNING
The SRSET command takes effect immediately. If you set the offset angle
incorrectly the system may become unstable.
3. Issue a DRESET command. The drive stores the value for the offset angle into
nonvolatile memory. It uses this value for all future operations. You do not need to
perform this procedure again.
