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
∗
10
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.
