Start signal
With PNU A002, you specify how the start signal is to be issued:
• through digital inputs, for example the FW input or a digital
input configured as REV,
• with the ON key on the keypad,
• through the RS 485 serial interface,
• through slot 1 or 2 for optional modules.
Base frequency
The base frequency is the frequency at which the output voltage
has its maximum value.
End frequency
If a constant-voltage frequency range exists beyond the transition
frequency set with PNU A003 , define this range with PNU A004 .
The maximum end frequency must not be smaller than the base
frequency.
