The LCD indicates the settings which the drive inverter is presently using.

Start motor The inverter is started by pressing the key. This key is deactivated in the default setting.

Parameter P0700 or P0719 should be changed as follows to activate the key:

OP: P0700 = 1 or P0719 = 0 ... 16

OFF1 When this key is pressed, the motor comes to a standstill within the selected

ramp-down time. It is deactivated in the default setting; to activate → refer to the

"Start motor" key.

Stop motor

OFF2 The motor coasts down to a standstill by pressing the key twice (or pressing

once for a longer period of time). This function is always activated.

Direction

reversal

To reverse the direction of rotation of the motor, press this key. The opposing direction is

displayed using the minus character (-) or by the flashing decimal point. In the default

setting this function is deactivated. To activate it → refer to the "Start motor" key.

Jog motor In the "Ready to power-on" state, when this key is pressed, the motor starts and rotates

with the pre-set jog frequency. The motor stops when the key is released. When the motor

is rotating, this key has no effect.

Function This key can be used to display additional information.

If you press the key during operation, independent of the particular parameter, for two

seconds, the following data will be displayed:

1. Voltage of the DC current link (designated by d – units V).

2. Output current (A)

3. Output frequency (Hz)

4. Output voltage (designated by o – units V).

5. The value, selected in P0005 (if P0005 is configured so that one of the above pieces

of data is displayed (1 to 4), then the associated value is not re-displayed).

The displays mentioned above are run-through one after the other by pressing again.

Step function

Starting from any parameter (rXXXX or PXXXX), if the key Fn is briefly pressed, then a

jump is immediately made to r0000. You can then, when required, change an additional

parameter. After returning to r0000, when key Fn is pressed, then the system returns to

the starting point.
