accuracy and the signal-to-noise ratio will be reduced. Contact Delta Computer Systems,
Inc. to discuss options for your application.
Both Resolver interfaces on a Resolver (R) module must always be set to the identical
Reference Amplitude. Changing the Reference Amplitude on one input will automatically
change it on the other input.
Because this parameter affects motion, the axis must be disabled or in Direct Output
before writing to this parameter. The Enabled and Direct Output Status Bits indicate these
states of the axis. When changing this parameter from RMCTools, the software will
automatically do this for you. This may cause a halt on the axis, which is expected.
9.2.2.2.23.19. Reference Frequency
Type: Axis Parameter Register
RMC70 Address: %MDn.14, where n = 12+ the axis number
RMC150 Address: %MDn.14, where n = 24+ the axis number
System Tag: _Axis[n].RefFreq, where n is the axis number
How to Find: Axes Parameters Pane, Setup tab: Primary Control Setup
Data Type: REAL
Units: Hz
Range: 800-5000
Default Value: 2500
Description
This parameter applies only to the Resolver (R) module. This parameter specifies the
frequency of the reference signal transmitted by the Resolver (R) module to the resolver
device. This value should be set to the frequency specified by the datasheet of the
resolver device.
Note: This parameter does not apply to the RW module.
Changing this Parameter
Both Resolver interfaces on a Resolver (R) module must always set to the identical
Reference Frequency. Changing the Reference Frequency on one input will automatically
change it on the other input.

before writing to this parameter. The Enabled and Direct Output Status Bits indicate these
