.. _movej_h2r:

movej_h2r
------------------------------------------

This function moves the robot to a target position in joint space. It is a hold-to-run version of the movej command.
It initiates the motion, which must be sustained by periodically calling the hold2run command.

      return _safe_movej_h2r(_rbtCtrl, fTargetPos, fTargetVel, fTargetAcc, fTargetTime, eMoveMode, fBlendingRadius, eBlendingType);
