Operation of the Unit
CP.11 Heat sink temperature
Display of the actual heat sink temperature in °C. First a pre-warning can be given via digital output if the
heat sink temperature is too high, so a controlled deceleration of the unit is possible. The modulation is shut
off and the unit de-activated when reaching the max. heat sink temperature, if there is no reaction to the
pre-warning.
CP.12 Over load counter
The average load of the COMBIVERT R6-S can be evaluated with this parameter in order to avoid an E.OL
error (time based overload). When the actual load goes above 105%, the counter begins to increment. The
Error E.OL is triggered, if the overload counter reaches 100 %.
CP.13 Active power
CP.13 displays the actual active power of the COMBIVERT R6-S. Motor power is displayed with positive
values, generated power is displayed with negative values.
CP.17 Apparent power / Line input
Display of the actual apparent power at the mains input (kVA).
CP.18 Analog output 1 / amplifi cation factor
This serves as a gain for the analog output 1. This output provides a signal in a range of 0...10 VDC =
0...150 % I which corresponds to the DC-bus current. The gain can be adjusted with CP.18 in a range of
DC
0...±20,00. With this parameter, the analog output signal can be adapted to individual requirements.
CP.19 DC Bus switching level
This sets a voltage threshold for the switching of the relay output R2, which is programmed to control the
line contactor when Wiring Scheme B is utilized (Section 4.4.4 or 4.4.5). During power on, when the DC bus
voltage rises above this value and the internal charging contactor of the R6 unit is closed, then the output is
activated. This allows the drive and regen unit to precharge and power up together. If the line supply drops
below this value during power off or during operation due to line sag and/or DC bus sag under (motoric)
load, then the output controlling the line contactor would deactivate, causing the line contactor to open; if
this occurs, the input line phases would not be detected by the commutation choke synchronization module,
causing an E.net fault. Nominal and minimum settings based on line supply voltage are as follows:
Line Voltage - VAC
460
400-415
230
208
Setting this value too low when Wiring Scheme B is utilized (Section 4.4.4 or 4.4.5), or not
utilizing the line contactor control for power up of the units may cause damage.
