The KEB COMBIVERT F4-F permits the storing and the position-controlled approach
of up to 8 positions. The position setting is based on the parameter set programming,
at that one position can be deposited in each parameter set.
The position setting and display can be done either in increments or revolutions. Through
the Teach-function it is possible to read-in the actual position as setpoint position
value.
Basically one revolution is devided into 65536 (2
signals 1 Vss allow the utilization of this high resolution.)
The entire value range for position settings lies at 4.294.967.296 (2
The positioning can be done relative to the actual position or to a fixed absolute position.
The drive profile (maximum speed, ramps, position controller) is individually adjustable
for every positioning set.
Parameters Pc.0, Pd.0 and Sn.0 permit the change between the different modes (see
Fig. 6.11.1).

1) following restrictions apply to this setting:
- no speed-dependent K
- fast setpoint setting (SP .0 = 18) is not possible
- the standstill position controller CS.14 has no function
The changeover from Pc.0 can be done only at switched off modulation (operating
condition „nop"). When changing Pc.0 the inverter automatically carries out a restart.
At this the inverter is not ready for operation for a short time.

By means of a digital input (di.3...di.12) the synchronous module (value 9) or the
positioning module (value 22) can be deactivated and it can be changed to the standard
mode.
