12.2.10 Event 39: Overtemperature drive controller i2t
The possible effects depend on the configured level (U02):
§ 0: Inactive
§ 1: Message
§ 2: Warning
§ 3: Fault
The maximum permitted output current is limited to 100% of I
2N,PU
(R04). If the i
2
t value (E24) increases to 105%, event 59:
Overtemperature drive controller i2t is triggered.
The drive controller is interrupted if:
§ A29 = 0: Inactive for STOBER device controller
or
§ A540 = 0: disable drive, motor is free to rotate for CiA device controller
Response:
§ The power unit is disabled and axis movement is no longer controlled by the drive controller
§ The brakes are no longer controlled by the drive controller and engage in the event of an inactive release override
(F06)
The drive controller is interrupted with a quick stop if:
§ A29 = 1: Active for STOBER device controller
or
§ A540 = 2: slow down on quick stop ramp for CiA device controller
Response:
§ The axis is stopped by a quick stop; meanwhile, the brakes are controlled by the drive controller and remain released
§ At the end of the quick stop, the power unit is disabled and axis movement is no longer controlled by the drive
controller; the brakes are no longer controlled by the drive controller and engage in the event of an inactive release
override (F06)
Cause Check and action
Wrong drive controller design Check the design and change the drive controller type if necessary
Increased or reduced mechanical
friction
Check the service status of the mechanics and service them if necessary
Mechanical block Check the output and correct the block if necessary
Short deceleration/acceleration
times
Check the actual current during the braking process using the scope image (E00);
reduce the deceleration and acceleration values if necessary
Clock frequency too high Check the utilization of the drive, taking into account derating and the configured
clock frequency (E20, B24); reduce the configured clock frequency or replace the
drive controller if necessary
