5 Frequency inverters – settings and displays

5.1 Frequency inverter bus parameters


To operate the inverter with the InterBus protocol, the bus must be connected to the master and some settings
have to be made on the frequency inverter.

With InterBus protocol, the inverter parameters are mapped in the range 2000

hex

to 23E7

hex

(= 8192

dec

to

9191

dec

), i.e. when parameterisation is carried out via the bus, the parameter numbers must be added to the

value 2000

hex

(e.g. P508

obj 21FC

hex

).



The frequency inverter can always be parameterised. Control of the inverter via InterBus can be activated by
setting parameter P509 to value 12, 13 or 14. (see below)

Parameter

Available in Option

P507

PPO type

Always visible

1 ... 4

[ 1 ]

Only with Profibus or InterBus option

1 = PPO type 1: InterBus with data length of 3 words (see Chap. 4.2.1)

2 = PPO type 2: InterBus with data length of 5 words (see Chap. 4.2.2)

3, 4 = PPO type 3, 4: reserved

Interface

Always visible

0 ... 21

[ 0 ]

valid for
SK 300/700/750E

Selection of the interface from which the inverter is controlled.

0 = Control terminals or keypad control with the Control Box (optional), the ParameterBox

(optional) or the potentiometer option.

1 = Control terminals only. The inverter can only be controlled via the digital inputs and the analog

input.

12= InterBus setpoint.

The frequency setpoint is transferred via InterBus

.

Control via the digital inputs

is still active.

13= InterBus control word. The control signals (enable, rotational direction ...) are transferred via
InterBus, the setpoint via the analog input or the fixed frequencies.

14= InterBus. All control data and setpoints are transferred via InterBus. The analog input and the
digital inputs have no function (except safety functions, see below)

P510

Auxiliary setpoint interface

Always visible

0 ... 7

[ 0 ]

valid for
SK 300/700/750E

Selection of the interface from which the inverter is controlled.

0 = Auto: The auxiliary setpoint value is automatically

taken from the interface of the master setpoint value
