Technical description 8100_A
7.4 DISPLAY PARAMETERS
Display parameters can only be read.
7.4.1 DISPLAYSET-VALUE2 C049
C049 shows the momentary set-value 2 (in % fdmax). Independently of the
operating mode. set-value 2 is always provided via the control terminals 1, 2, and
not via the LECOMinterface or the keypad 810288.
With suitable configuration (see 7.1.6) set-value 2 is added internally to set-value 1
(C046). The total is limited internally to :I::fdmax'
7.4.2 OUTPUT FREQUENCYC050
C050 shows the actual running frequency in Hz.
7.4.3 ACTUALVALUEOF PI-CONTROLLER
Code C051 shows the actual value of the PI-controller. Depending on the display of
set-value 1 (C046). you can select with C172 a scaled display (in % fdmax)or an
absolute display (in Hz).
In open-Ioop control, "0" is shown with C051.
7.4.4 MOTOR VOLTAGEC052
C052 shows the actual output voltage and therefore the motor voltage in Volts.
Caution! Even when the display shows "OV". the motor terminals may carry
voltage. 8efore working on the motor side. always disconnect the
controller from mains and wait at least 30 seconds.
7.4.5 DC BUSVOLTAGEC053
CO53 shows the actual DC bus voltage in Volts.
7.4.6 TRIP FAULT INDICATIONC0067
Code C067 displays a momentary fault (see 8). The fault can also be reset under this
code.
Reset faults are saved in the history butter and can be read using the LECOM
interface with codes C161 to C168. When using the operating unit 810288. they
can be displayed by pressing the . key. A maximum of eight fault indications can
be read; the last fault is displayed first. then the one before and so on.
