Chapter 2 Stand Alone Regulator Installation, Wiring and Configuration
Relay Output and Thermistor/Thermal Switch Wiring
Two normally open relay outputs and one motor thermistor (PTC) or thermal
switch input are available for use and must be configured with the appropriate
parameters. See “Relay Outputs” and “Thermistors and Thermal Switches” in the
PowerFlex Digital DC Drive User Manual, publication
20P-UM001 for details.
I/O, Digital Encoder, and DC Analog Tachometer Wiring
The following standard I/O and feedback options are available with the SAR.
• Eight digital inputs, four digital outputs, three analog inputs, and two
analog outputs are available. Additional digital and analog I/O is available
when using the optional I/O expansion circuit board.
• An input terminal block is available for an incremental, dual channel, two
channel optional (with jumper), differential (recommended) or single-
ended encoder with an input voltage configurable for +2.5V…5.2V or
+5.4V…15.2V.
• An input terminal block is available for a DC analog tachometer with a
maximum input voltage of 22.7V, 45.4V, 90.7V, 181.6V, or 302.9V and an
input current of 8 mA full scale.
See “I/O Wiring” in the PowerFlex Digital DC Drive User Manual, publication
20P-UM001 for details.
Resolver Feedback Option Module Wiring
A resolver feedback module is available for purchase separately from the SAR.
The resolver feedback option module includes the PowerFlex DC Drive Resolver
Feedback Option Module Installation Instructions, publication
20P-IN071 . See
the PowerFlex Digital DC Drive User Manual, publication 20P-UM001 for
resolver configuration details.
SAR Motor Field Current
Configuration
The SAR motor field current must be configured with both a hardware DIP
switch (S14) and by setting parameter 374 [Drv Fld Brdg Cur] to the appropriate
value. For each field current rating, in this case 40 and 70 A, there are several
ranges to choose from with regard to the maximum range of the field current.
The lowest range that is greater than the maximum motor field current should be
selected to ensure the best resolution. See “Field Current Configuration” in the
PowerFlex Digital DC Drive User Manual, publication
20P-UM001 for
instructions.
