11.1.7
Power monitoring for the brake chopper
Power monitoring for the internal brake resistor is implemented in the operating software.
When the power monitoring “I²t brake chopper” reaches 100% the power of the internal brake resistor is switched back to the
rated output power.
11.1.8
I²t monitoring for the PFC stage
I²t monitoring for the PFC is implemented in the operating software (except the C 1-08).
11.1.9
Initial operation status
Servo positioning controllers, which are sent to item for service, will be equipped with a different firmware and other
parameters for testing purposes.
Before the next initial operation at the customer the item servo positioning controller C 1-Series must be parameterized again.
The parameterisation software item Motion Soft
queries the initial operation status and asks the user to parameterize the
servo positioning controller. At the same time the device shows an “A” on the seven-segment display to indicate that it is ready
but not yet parameterized.
11.1.10
Rapid discharge of the DC bus
If the system detects a failure of the mains supply, the DC bus is rapidly discharged within the safety period in accordance with
EN 60204-1.
Delayed activation of the brake chopper according to power classes in the case of parallel operation and mains supply failure
ensures that the main energy during rapid discharge of the DC bus is taken over through the braking resistors of the higher
power classes.
11.1.11
Operating hours counter
An operating hours counter is implemented, which has been designed for at least 200 000 operating hours. The operating
hours counter is displayed in the parameterisation software item Motion Soft
.
