Detailed Description of the Parameters
.
CTW900 | 107
NOTE!
For converters of Size D (1500A and 2000A), the indication in P0030 will correspond to the
temperature of the field bridge heatsink.
P0132 – Maximum Overspeed Level
Adjustable Range:
0 to 100 %
Factory Setting:
10 %
Properties:
Groups of
01 PARAMETER GROUPS or 01 PARAMETER GROUPS
Access via HMI:
23 Limits
........
38 Protections
........
Description:
This parameter establishes the highest speed value at which the motor can operate, and it must be set with a
percentage of the maximum speed limit (P0134).
Therefore, when the effective speed exceeds the value of P0134+P0132 for over two seconds, the CTW900 will
disable the armature firing and will indicate the Overspeed fault (F150).
If you wish to disable this protection, set P0132 = 0 %.
Note:
Function active only in the control mode “Speed+Torque” (P0299 = 0).
P0135 – Maximum Output Current
Adjustable Range:
0 to 1.25x I
rat
Factory Setting:
1.0x I
rat
Properties:
Groups of
01 PARAMETER GROUPS or 01 PARAMETER GROUPS
Access via HMI:
23 Limits
........
38 Protections
........
Description:
It establishes the maximum level that the output current can reach without the actuation of the Overcurrent.
In case the effective current (P0003) exceeds the value defined in P0135 for over two seconds, the CTW900 will
disable the armature firing and will display the fault F071.
P0137 – Time for Stall Protection
Adjustable Range:
0 to 100 s
Factory Setting:
2 s
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It defines the time for the actuation of the Stall protection (F077), which monitors the motor speed and current
according to the values defined in P0139 and P0355.
Thus, when the conditions of P0139 and P0355 are met, the protection will actuate after the time set in P0137
has elapsed.
P0139 – Speed for Stall Protection
Adjustable Range:
0 to 1000 rpm
Factory Setting:
18 rpm
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
38 Protections
........
Description:
It establishes the speed below which the motor shaft will be considered locked so as to enable the Stall
Protection (F077).
