Operating Instructions ACU
15.10.3 Controlling the Motor via the Control Unit
Parameter Reference Frequency Source 475 enables linking of the reference sources in the
reference frequency channel. The operation modes can be set without the function "Motorpoti (KP)".
If an operation mode without „Motorpoti (KP)“ is selected, a connected motor can be controlled via
the keys of the control unit KP 500.
The function is activated as described in Chapter 15.10.3 "15.10.3".
The speed of the modification of the reference value is limited by parameter Ramp Keypad-
Motorpoti 473.
15.11 PWM-/repetition frequency input
The use of a PWM (pulse-width modulated) frequency signal completes the various possibilities of
the reference value specification. The signal at one of the available digital inputs is evaluated
according to the selected Operation Mode 496.
PWM frequencies ranging from 50 Hz to 150 kHz can be evaluated.
The PWM signal or repetition frequency are zero.
