Description of power section parameters
Parameters
Ramp monitoring
index 8928.0
This parameter is used to activate ramp monitoring:
• Setting range: YES / NO
If you set the deceleration ramps to a value that is much shorter than can be physically
achieved in the system, the rotating drive will be stopped once the monitoring time has
expired.
The respective ramp time also has to be increased, if the ramp timeout is definitely
triggered by a preset ramp that cannot be traveled. This parameter is an additional
monitoring function for speed monitoring. However, it only applies to the deceleration
ramp. This means the parameter can be used to monitor the deceleration ramp, stop
ramp or emergency stop ramp if speed monitoring is not desired.

Ramp t3 up/down
index 8486.0,
8467.0
These parameters are used to set ramp t3:
• Unit: [s]
• Setting range: 0.2 – 20 – 2000 s
The ramp is active when the terminal assignment in the command PCB was configured
to motor potentiometer right or motor potentiometer left.
The ramp times refer to a setpoint step change of
쑶
n = 3000 rpm.
Save last setpoint
index 8488.0
• ON: If MOTOR POT UP and MOTOR POT DOWN = "0," the last applicable motor
potentiometer setpoint is stored in the non-volatile memory 2 s afterwards. The last
motor potentiometer setpoint takes effect again after power off and power on.
• OFF: Following power off/power on or after withdrawal of the enable signal, the
inverter starts with minimum speed index 8516.0.
