will increase until that condition is met. By adding an additional derivative limit on following
error, the servo will fault within milliseconds of contact with an object.
EXAMPLE:
DEL=VT 'Set limit to commanded speed
If dE/dt equals commanded velocity, then the motor just hit a hard stop. Normally, the motor
would have to continue applying torque until the normal following error is exceeded.
However, if DEL (dE/dt limit) is set to target velocity (VT), then as soon as contact is made
with a hard stop, the controller will immediately fault without any wind up.
