8902/RE Resolver Speed Feedback Option
Initial Set-up
Configuring the 890 Drive
Note:
The DSE 890 Configuration Tool is Parker SSD Drives’ Windows-based block
programming software and is supplied with each drive.
Use the DSE 890 Configuration Tool to configure the RESOLVER function block, as detailed
below.
You will require a PMAC (Permanent Magnet AC) Configuration when using DSE 890: create
a "New Configuration" in DSE 890 and select "890 Permanent Magnet AC" in the dialog box.
Double-click on the MOTOR CONTROL function block in the new configuration to display the
RESOLVER function block.
DSE 890 offers a "Motor Wizard" to quickly enter parameter information into the RESOLVER
function block: from the menu at the top of the screen select Edit
→
Motor Wizard. In the pop-
up dialog box you can now select the motor and resolver from the drop-down lists.
Alternatively, you can enter parameter information directly into the RESOLVER function block.
The parameters are described below.
RESOLVER Function Block
SETUP::MOTOR CONTROL::RESOLVER
This block allows Speed Feedback to be measured using a resolver.
Note:
Only parameters relevant to the Resolver are described below.
Parameter Descriptions
NAME
Range:
Resolver name/designation
POLES
Range: 2 to 20
Number of resolver poles. In case of multi-pair poles resolver, the resolution of the resolver
option is multiplied by the number of pair poles.
RATIO
Range: 0.2 to 1.0
Transformation ratio of the resolver
SPEED MAX
Range: 0 to 2
31
(user units)
Mechanical maximum speed supported by the resolver.
ACCURACY
Range: 0 to 60.0 minutes
This parameter represents the nominal accuracy of the resolver. (This information is only
informative and could be left unspecified).
CARRIER VOLTAGE
Range: 5.0 to 10.0 Vrms
This parameter represents the nominal carrier voltage for the resolver. (This information is
only informative and could be left unspecified).
CURRENT
Range: 0.0 to 70mA rms
This information represents the nominal current needed to run the resolver. (This information
is only informative and could be left unspecified).
INERTIA
Range: 10.0 to 100000 Kgcm²
This information represents the resolver rotor inertia. (This information is only informative
and could be left unspecified).
