After applying the coding to the inputs, the desired travel job can be started by a positive
slope on the PCM Start input.
Resetting the PCM Start input during an active positioning process will result in cancellation
of the travel job but the drive will continue to be controlled.
An example of calling travel data set no. 3 is shown below
Step 1: Create number of travel data set
Step 2: Starting the positioning job
4.1.2 Current limiting
Measuring the supply current cannot indicate the actual motor current. With
cycled output stages, the supply current does not correspond to the motor
current. Actual motor current can be read via the interface.
The current limit is set via Parameter Current Limiting (Object 2619h), which serves primarily
for protecting the drive against overload.
With the default set, the nominal torque indicated on the product data sheet is achieved.
Drive overload results in limiting the motor current to the set value.
As a consequence, the actuator cannot maintain the speed set, the contouring error increases.
The actuator changes to the error status if the contouring error exceeds the contouring error
limit defined by the Contouring Error Limit parameter (Object 2618h): Contouring error.
