Operation of the Device

5.1

Operation with PC and system software COMBIVIS

Instructions for the installation and operation of the system software COMBIVIS can be taken
from the appropriate software instruction.
5.2

Switch-on procedure

The COMBIVERT R6-S is initialized after connection of the supply voltage. The power unit
code is checked first. When an invalid power unit is recognized, error "E.Puci" (Power unit
code invalid) is released and displayed in the operator. This error cannot be reset, the power
unit must be checked.
The COMBIVERT R6-S changes into synchronisation phase if a valid power unit is recog-
nized. The following procedures take place one after another during this synchronisation
phase:
• Check for correct synchronisation connection (if a synchronisation signal is missing, error
"E.nEt" is triggered)
• Checking the phase allocation of synchronous signals to the mains phases. If a phase is
missing or a phase allocation error occurs, error "E.SYn" is triggered.
The current mains frequency and mains voltage are determined after successful synchro-
nisation. The correct connection of the COMBIVERT R6-S is now ensured. If the control
release (terminal ST) is set, the COMBIVERT R6-S now independently starts the intended
operation. Depending whether regenerative requirement is available, the COMBIVERT R6-S
is in status "rEGEn" or "Stb".
Status "Stb"
COMBIVERT R6-S detects a typical voltage level in the DC link circuit of the connected fre-
quency inverter (motor operation) and keeps the modulation signals of the regenerative unit
deactivated.
Status "rEGEn"
If the DC voltage in the DC link (CP.09 or ru.19) exceeds the value of the regeneration level
(CP.34 or cs.02) referring to the reference value ru.18, the modulation signals are activated
and the unit changes into regenerative operation. The regenerative unit is switched active, if
regenerative operation is requested by an additional installed COMBIVERT R6-S in the sys-
tem (master /slave operation).
