Start Lock Kp (I20) is the proportional gain with units of (user units/s) / user unit. A Start Lock Kp (I20) of unity and a position error of one user unit will
give a position control loop speed of 1 user unit/s.
This sets the position loop proportional gain speed clamp i.e. the maximum speed used to correct the motor position, used to hold the position of the
motor when releasing the brake. This is used when Start Lock Enable (I22) = On (1).
When set to Off (0), position lock control is disabled.
When set to On (1), position lock control is enabled. The position loop is used to maintain the position of the motor on brake release. If a previous
travel has been completed, the position of the motor after the brake has been applied but before the drive is disabled is stored and used as the set
point position on the next start.
In Open loop mode this is not available.
Position locking Start Lock Enable (I22) must not be used at the same time as load cell compensation Load Cell Compensation Enable (E10).
