P0363 – Maximum Line Unbalance
Adjustable Range:
0 to 30 %
Factory Setting:
15 %
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It determines the maximum limit of unbalance between the line voltages (P0033, P0034 and P0035) for the
actuation of the protection against line voltage unbalance (F006). Its value is expressed in percentage of the
rated voltage configured in P0296.
Thus, if the difference between the values of the line voltages remains above the value set in P0363 for more
than two seconds, the converter will be disabled by fault F006.
For the percentage calculation of the difference between the line voltages, the following relations are used:

NOTE!
The protection will be disabled if P0363 is set to 0 %.
P0364 – Maximum Variation of the Line Frequency
Adjustable Range:
1 to 10 %
Factory Setting:
5 %
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It defines the limits of the variation in the line frequency (P0005) for the actuation of the protections against
frequency out of range (F008). Its value is expressed in percentage of the rated frequency of the supply line (50
Hz or 60 Hz).
With this protection, when the line frequency (P0005) is below or above the maximum variation set in P0364, the
converter will be disabled by fault F008.
The upper and lower limits for the actuation of the protection can be obtained from the equation below:
(

Note:
■
Parameter P0364 also defines the maximum variation allowed for the field supply frequency when it is
supplied externally (through connector X3). In this case, if the field supply frequency is out of the accepted
range, the converter will be disabled by fault F009.

Communication [39]
In order to exchange information via communication network, the CTW900 features several standardized
communication protocols, such as MODBUS, Profibus, CANopen, DeviceNet, EtherNet/IP and PROFINET.
For further details regarding the inverter configuration to operate in those protocols, refer to the Modbus and
Anybus Communication Manual of the CTW900.
