Explanation of the parameters
Parameters
Requirements: Motor utilization is always determined based on the rated motor current.
Enter the duration of the machine cycle to receive an exact statement concerning the
utilization for the motor powering the machine cycle.
The following signal and display functions are available in conjunction with motor pro-
tection:
Set the following parameters:
P341 / P343 Type
of cooling 1 / 2
Setting range: FAN COOLED / FORCED COOLING
For calculation of the thermal motor load as described in P340 Motor protection 1 / P342
Motor protection 2 you will need to know the type of cooling for the motor.
P344 Interval for
motor protection
Setting range: 0.1 ... 4 ... 20 s
P344 is not relevant for asynchronous motors. For synchronous motors, this parameter
corresponds to the cycle time of the movement and is used for the function P006 Motor
utilization 1 / P007 Motor utilization 2 . The setting range is 100 ms ... 20000 ms.
You should always set the time for roundtrip travel (back and forth).
Parameters
Signal and display function
Display of motor utilization for parameter set 1. Valid after ca. 10 to 20
cycles or after ca 2 s and can be evaluated using IPOS
plus®
or from a
PLC.
In setting P340 = ON SERVO without function
In setting P340 = ON SERVO without function
Parameters
Meaning
P344 Motor protection interval
Corresponds to the machine cycle of the application.
Range: 0.1 s... 20 s
NOTE
Activating the function does not trigger monitoring or protection of the connected motor.
Protection must be guaranteed via TF/TH.
Setting a binary output to "Motor utilization_1" or "Motor utilization_2" also has no effect
when P340 is set to ON SERVO.
