000 – Sets the address of the inverter when the serial
030 interface is used. (See section 7 for further details.)
(000)
Sets the parity and baud rate of the serial address:
Parity
000 Even
001 Even
002 Even
003 Odd
004 Odd
005 Odd
006 Ignored
007 Ignored
008 Ignored
Note: The master unit must still transmit a parity
bit in each byte.

000 15 ms debounce of digital inputs
(for relays or switches).
001 No debounce
– suitable for transistor–controlled inputs in control
systems which require a fast response.
(000)
000
Normal operation – fixed frequency disabled.
001
Selects fixed frequencies. In this mode the
inverter only outputs fixed frequencies, ramping
between the fixed frequencies at rates set by P02
and P03. The fixed frequencies are selected using
and terminals (X11.17 and X11.18) in
accordance with the following table:
(1 = 7 – 33 V)
(0 = < 7 V)
002
Allows three fixed frequencies (P26, P27 & P28)
and one analogue set–point in accordance with
the following table:
Note: 002 is only valid if P04 is set to 000, 001,
002, 007, 008 or 009.
