PARAMETER AND VARIABLE DESCRIPTIONS
1557-UM050F-EN-P – June 2013
Drive Control Firmware Revision Number [Drive contrl FRN]
Linear number:
15
Minimum value:
0.00
Maximum value:
99.99
Default value:
N/A
This parameter specifies the revision of firmware installed in the Drive Control boards. Changing the value of
this parameter has no effect.
Prior to Rev 4.60/5
.10, this parameter was called simply “Firmware Revision”.
Communications Processor Firmware Revision Number [Comm proc FRN]
Linear number:
16
Minimum value:
0.00
Maximum value:
99.99
Default value:
N/A
This parameter specifies the revision of firmware installed in the Communications Processor board. Changing
the value of this parameter has no effect.
This parameter was added in Rev 4.60/5.10.
2 Nameplate Parameters
Rated Line Frequency [Rated line freq]
Linear number:
17
Minimum value:
50 Hz
Maximum value:
60 Hz
Default value:
60 Hz
This parameter specifies the rated frequency of the drive, and must be set to either 50 Hz or 60 Hz.
Capacitor kvar [Capacitor kvar]
Linear number:
20
Minimum value:
1 kvar
Maximum value:
7500 kvar
Default value:
100 kvar
This parameter specifies the total three phase nameplate kvar of the motor filter capacitors.
Capacitor Volts [Capacitor volts]
Linear number:
21
Minimum value:
1000 V
Maximum value:
10000 V
Default value:
2400 V
This parameter specifies the nameplate voltage rating of the motor filter capacitors. If the rated capacitor
voltage is less than the rated motor voltage then the drive assumes that the capacitors are connected in wye
and multiplies the rated capacitor voltage by
3. Otherwise the drive assumes that the capacitors are
connected in delta and uses this parameter unchanged.
Prior to Rev 4.60/5.10, this parameter specified line to line rated voltage regardless of the capacitor connection.
