Detailed Description of the Parameters
.
112 | CTW900
Description:
It defines the maximum overvoltage level in the armature in relation to the motor rated voltage (P0400).
With this setting, when the armature voltage (P0007) exceeds the value of [(100 % + P0358) x P0400] for more
than two seconds, the converter will be disabled by fault F022.
NOTE!
The protection will be disabled if P0358 is set to 0 %.
P0359 – Maximum Overcurrent in the Field
Adjustable Range:
0 to 35 %
Factory Setting:
10 %
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It determines the maximum overcurrent level in the field in relation to the rated current set in P0404.
Thus, when the field current (P0008) exceeds the value of [(100 % + P0359) x P0404] for a more than two
seconds, the converter will be disabled by fault F070.
NOTE!
The protection will be disabled if P0359 is set to 0 %.
P0361 – Maximum Overvoltage in the Line
Adjustable Range:
0 to 30 %
Factory Setting:
15 %
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It defines the maximum overvoltage level in the line in relation to the rated voltage configured in P0296.
With this protection, when the line voltage (P0004) exceeds the value of [(100 % + P0361) x P0296] for more
than five seconds, the converter will be disabled by fault F004.
NOTE!
The protection will be disabled if P0361 is set to 0 %.
P0362 – Undervoltage Level in the Line
Adjustable Range:
0 to 30 %
Factory Setting:
20 %
Properties:
CFG1
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It establishes the level for the actuation of the protection against undervoltage in the line (F003) in relation to the
rated voltage configured in P0296.
With this protection, when the line voltage (P0004) falls below the value of [100 % – P0362) x P0296] for a
period over the setting in P0357, the converter will be disabled by fault F003.
