The goal is to adjust timer US.17

such that the pre-torque ramp down

phase occurs exactly when the brake

releases and the roll back occurs.

Note: by monitoring LF.86 it is possible

to see what phase the drive is in. A

value of 4 is the ramp up phase and

is controlled by US.17. A value of 3

is the ramp down phase US.18.

When adjusted properly, the brake

should pick, the motor holds the load

for a short period about ¼ second,

and then the acceleration begins.
