Response of the new version:
The controlled accelerating current C0995/2 is activated for an acceleration/deceleration ramp (C0012/C0013) of up to t=80s.
This also leads to an improved reversing behaviour.
Fluctuations of the analog input no longer have an influence on accelerating current and standstill current.
What happens?
The controlled accelerating current C0995/2 is only activated for a maximum acceleration ramp of t=17s. During reversing, this may lead to an overcurrent interruption or stalling of the machine.
In the controlled range, the current fluctuates between standstill current C995/1 and accelerating current C995/2.
The problem only occurs when using the analog input as setpoint.
When does this behaviour occur?
The behaviour occurs when using the SLPSM control mode and ramp times C0012/C0013 > 17 s in conjunction with the analog input.
Which products are affected?
Inverter Drives 8400 StateLine FW V13.01.00.00 - V15.00.00
Inverter Drives 8400 HighLine FW V13.01.00.00 - V15.00.00
Inverter Drives 8400 TopLine FW V13.01.00.00 - V15.00.00
Short-term measures:
Set standstill current C0995/1 and accelerating current C0995/2 to the same value.
Evaluation/recommendations:
With the same setting for standstill current C0995/1 and accelerating current C995/2, there will be an increased temperature rise of the machine at standstill. This may reduce the service life of the motor.
