Parameterization Rexroth IndraDrive FCS01.1
DOK-INDRV*--FCS01*****-IB01_EN-P
Functions pulse input: 2...22kHz (only for DIG 2 and DIG 3)
For these functions, the respective inputs evaluates the applied pulse
frequency. The frequency range 2kHz to 22kHz covers the value range 0
to 100%. The inputs act up to a maximum pulse frequency of 32kHz. The
voltage level may be between 15V and 24V and the duty-cycle between
50% and 80%.

Maximum frequency
2
In analog range, the maximum frequency of the FU is
set. 100% corresponds to the setting in parameter
P411. 0% corresponds to the setting in parameter
P410. The value cannot fall below the values for the
min./max. output frequency (P104/P105) or exceed
them. Pulses

is needed to establish a control loop. The analog input
(actual value) is compared to the setpoint value (e.g.
another analog input, or fixed frequency). The output
frequency is adjusted as far as possible until the
actual value has approached the setpoint.
(see controlled variables P413 - P416).
The output frequency cannot fall below the
programmed value of the minimum frequency in
parameter P104. (no rotation direction reversal)

this function allows for teaching the controller in
advance a value for the torque requirement
(feedforward control). In lifting gears with separate
load sensing function, this function can be used to
ensure better load transfer.

The limits of these values are determined by the parameter >Minimum frequency secondary setpoints< P410 and
the parameter >Maximum frequency secondary setpoints< P411.
