Note:
The parameter Ref Speed High must always be larger than Ref Speed Low. If the parameter Ref
Ramp is set to zero, a jump is executed. A negative ramp end point can be achieved with the
Direction command. The Direction command should be executed before the Reference command is
set. The direction may only be changed once per complete cycle.
The Reference command can be reset earlier. If the Special Mode is set to 2, reset the Reference
command means an abort. In this case, the sequence would have to correspond the image below to
complete the cycle.
Process Reference: Edge Prestop = 0
If Edge Prestop = 1, an inversion of Prestop produces the same course
Process Reference: Edge Prestop = 0
If the limit switch already appears during the ascending ramp, the frequency is then ramped down at
the current position. If the limit switch already appears during the reverse ramp, the ramp is stopped at
the current position.
