PowerFlex 4 Custom Firmware 3
P042 [Initial Braking Pressure]
It is adjustable from 80 (minimum initial braking pressure) to 2000 (maximum
initial braking pressure). The standard software version applied minimal initial
brake “pressure” to minimize “jerk”, but let drive coast an extended period before
braking became effective. A larger value in the parameter increase the initial
braking force. A value of 2000 during testing with standard motors may result in
“cogging” and noise. 1200 to 1600 will give good performance in general, but some
modification in this range may yield better operation.
P080 [DC Braking Time]
Set to 0.1 sec for testing.
This is the maximum amount of time the DC brake will be applied.
P081 [DC Braking Current]
Set to maximum for testing (1.8 time drive rated output current).
