Detailed Description of the Parameters
.
CTW900 | 105
NOTE!
In case the options 6 to 9 are selected for a converter class 05 (200 to 500 V), the message
“Hardware incompatible with this option” will be displayed, and the configuration will be disabled.
P0298 – Converter Type
Adjustable Range:
0 = Single Bridge
Factory Setting:
According to
1 = Double Bridge
model of the
converter
Properties:
CFG2
Groups of
01 PARAMETER GROUPS
Access via HMI:
36 Drive Data
........
Description:
It defines the type of the CTW900 in relation to the configuration of the armature bridge:
■
option 0 (Single Bridge) = converter Unidirectional (1-Q);
■
option 1 (Double Bridge) = converter Antiparallel (4-Q).
Antiparallel converters enable the operation of the motor in the four quadrants of the curve Torque x Speed
(Figure 4.1), while Unidirectional converters allow the operation of the motor only in the first quadrant.
NOTE!
For converters of the Antiparallel type (CTW900
A
), it is possible to configure them to operate just in
the Unidirectional mode by changing the setting of P0298 to option 0.
P0642 – Self-Diagnose
Adjustable Range:
0000h to FFFFh
Factory Setting:
Properties:
RO
Groups of
01 PARAMETER GROUPS
Access via HMI:
36 Drive Data
........
Description:
It informs the failure code when the “Self-Diagnose” fault (F084) is identified.
In case this fault occurs after the power-up, check the value contained in this parameter and contact WEG for
further details.
7.3.17
Motor Data [37]
In this group are the parameters for the setting of the characteristics of the motor used. They must be
configured according to the data on the motor nameplate or on its data sheet (if available).
P0400 – Armature Rated Voltage
Adjustable Range:
0 to 1200 V
Factory Setting:
400 V
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
Access via HMI:
37 Motor Data
........
Description:
Rated voltage of the motor armature, at which the motor reaches its rated speed (for full field).
Set according to the data on the motor nameplate.
