Operation
Limits the rate of the change of the signal.
The input signal (IN) is connected directly to the output (O) if the input signal does not
exceed the defined step change limits (STEP+ and STEP-). If the input signal change
exceeds these limits, the output signal change is limited by the maximum step change
(STEP+/STEP- depending on the direction of rotation). After this, the output signal is
accelerated/decelerated by the defined ramp value (SLOPE+/SLOPE-) per second until
the input and output signal values are equal.
The output is limited by the defined minimum and maximum values (OLL and OHL). If
the actual value of the output falls below the specified minimum limit (OLL), output O=LL
is set to 1. If the actual value of the output exceeds the specified maximum limit (OHL),
output O=HL is set to 1.
If the balancing input (BAL) is set to 1, the output (O) is set to the value of the balance
reference input (BAL_ref). Balancing reference is also limited by the minimum and
maximum values (OLL and OHL).
