SA3100 Drive Configuration and Programming

C.7 Diagnostic Variables

The programmer enters the values in the diagnostic variables to establish thresholds

at which drive warnings are generated.

RES_GAN% Resolver Gain

When RES_GA% is equal to zero, the gain

tuning procedure is performed automatically by

the operating system. Zero is the default value.

The value can range from 0 to 255 counts, with

1 count representing 0.15 volts of gain.

Units: Counts

Default Value: 0

Low Limit: 0

High Limit: 255

Step: 1

This value should be generated using the auto-tuning procedure because the PMI

Processor can take into account the entire resolver circuit when setting the proper

gain value.

If the gain needs to be re-calibrated, reset the value of RES_GAN% to zero.

However, do not reset the value of RES_GAN% to zero while the inner loop is

running (i.e., TRQ_ON@ is set). If the value is adjusted too low, a drive fault

(register 202/1202, bit 8) will occur.

GIT_E1% Ground Current Warning Threshold

A drive warning is generated (203/1203, bit 4) if

ground current exceeds the value stored in this

variable. The value is entered in amps times

10, e.g., 10.1 amps is entered as 101.

Units: Amps

∗

Default Value: 100

Low Limit: 10

High Limit: 2000

Step: 1

This value should be set above the value in the ground current feedback register

(208/1208) after the drive is operational.
