Once current regulator diagnostic is executed, step current response can be observed from trace
function or current probes on w-phase. It is recommended to use current probe to observe step
current response. Figure 4 shows (current probe) the step current response of w-phase when
Current Reg diagnostic function is executed. In this figure, 25% step rated motor current is
commanded. The step level can be controlled by parameter ParkI (inside Current Reg Diagnostic
function). Figure 5 shows the expanded version of Figure 4. The measured current loop response
is critically damped at 0.65 msec time constant (0 – 66.3% of final steady value), which is
approximately equal to the anticipated current regulator bandwidth response (1/1500 =
0.667msec).
