Start-up of a synchronous motor
The following chapter describes the initial start-up of a synchronous motor splitted in speed controlled systems
with encoder feedback (F5A-S) and speed controlled systems without encoder feedback (F5E-S).
6.2.2.1Start-up F5A-S
Steps 1 to 10 can be skiped when using a KEB servo system consisting of KEB COMBIVERT F5 and KEB
servo motor.
In this case the unit is already preset by a specific motor down load.
The following steps describe a standard start-up when using a "customer-specific motor“. Enocer interface 1 is
used as encoder feedback.
1.
Open control release
Deactivate terminal X2A.16
→ Inverter state ru.00 = noP/ „no control release“
2.
Selection of the speed range
The useable speed range is adjusted with ud.02:

The KEB COMBIVERT can have access to 8 parameter sets (0-7). Through programming the inverter can change
parameter sets autonomously and can thus start different modes of operation. This parameter shows the parameter
set, with which the inverter is operating currently. Independent of it another parameter set can be edited by bus (also
see chapter 7.14).

The motorpoti-function in the KEB COMBIVERT imitates a mechanical, motor operated potentiometer. The control
occurs via 2 programmable inputs („poti up“ and „poti down“). The display is limited by oP.53/54. The adjustment of the
motorpoti is done with the parameters oP.50...oP.59 (also see chapt. 15.3 „Motorpoti“). By way of the bus the motorpoti
can be set to any chosen value between -100...100%. In addition to the inputs the motorpoti can be operated with the
keys „UP“ and „DOWN“. Then the rate of change is not constant.

In order to preclude „E.OL“ - errors by too high load (load reduction in due time), the internal count of the OL-counter
can be made visible with this indication. At 100 % the inverter switches off with error „E.OL“. The error can be reset
only after a cooling time (blinking display „E.nOL“).
