BU 0500 GB-1013 103
Value Function Description Signal
34 Maximum frequency 2 3 The maximum frequency of the FI is set in the analog range. 100%
corresponds to the setting in parameter P411. 0% corresponds to the
setting in parameter P410. The values for the minimum/maximum
output frequencies (P104/P105) cannot be undershot/exceeded Impulse
35 Act.freq PID limited
2 3 Actual PID frequency limited, is required to set up a control loop. The
digital/analog input (actual value) is compared with the setpoint (e.g.
other analog input or fixed frequency). The output frequency is
adjusted as far as possible until the actual value equals the setpoint.
(see control variables P413 – P416)
The output frequency cannot fall below the programmed minimum
frequency value in parameter P104. (No rotation direction change!) Impulse
36 Act. freq. PID controlled
2 3
As function 35, >Actual frequency PID limited< but the FI switches
the output frequency off when the >Minimum frequency< P104 is
reached. Impulse
37 Servo mode torque
2
The motor torque can be set or limited via this function in Servo
mode. Impulse
38 Torque precontrol
2
A function which enables a value for the anticipated torque
requirement to be entered in the controller (interference factor
switching). This function can be used to improve the load take-up of
lifting equipment with separate load detection.

The limits of these values are set by the parameters >Minimum frequency auxiliary setpoints< P410 and >Maximum frequency
auxiliary setpoints< P411.

HTL encoder function (only DIN2/4 )
For the evaluation of an HTL encoder, the digital inputs DIN2 and DIN4 must be parameterised with
the following functions.

HTL
encoder
This function
can only be
used for digital
inputs 2 (DIN2)
and 4 (DIN4)
!
A 24V HTL encoder can be connected to DIN 2 and DIN 4 in order to
measure the speed. The maximum frequency at the DIN is limited to
10kHz. Accordingly, a suitable encoder (low pulse number) or
suitable mounting (slow speed) SHOULD BE USED.
The direction of counting can be changed by exchanging the
functions on the digital inputs.
Further settings are in P461, P462, P463.
