To use feedback control with velocity semifeedforward:
 Activate the velocity feedforward control with MP1391 and/or MP1392.
 Determine the k
v
factor for velocity feedforward control (MP1510.x).
 Activate the velocity semifeedforward control by entering the desired factor
in MP1396.x.
 Determine the k
v
factor for velocity semifeedforward control (MP1516.x).
 Enter MP1396.x = 1 to return to velocity feedforward control.
 For example, you may now use FN17: SYSWRITE ID 600 in an OEM cycle
to overwrite or reestablish the factor in MP1396.x.
