Ramp monitoring 1 / 2
Setting range:
YES
/ NO
If you set the deceleration ramps to a value that is a lot shorter than can be
physically accomplished in this system, the turning drive will be stopped after
expiration of the monitoring time. Such a setting will cause a fault signal and
increase brake wear.
This step also entails an increased setting of the respective ramp, if the ramp
timeout definitely appears in form of a preset ramp that cannot be traveled.
This parameter is an additional monitoring function for speed monitoring. This
parameter only applies to the downwards ramp. This means the parameter can
be used to monitor the downwards ramp, stop ramp or emergency stop ramp if
speed monitoring is not desired.

EEPROM will appear after about 100,000 storage operations.
Store only after setpoint change. If a fixed setpoint is deselected, the fixed
setpoint will be used as motor potentiometer value.
on / ON
The inverter starts with the last set motor potentiometer setpoint:
•
After power off and on
•
After revoking ENABLE
If a fixed setpoint is deselected, the old motor potentiometer setpoint will be
used again.

Fixed setpoints 1 / 2
You can activate the fixed setpoints via the binary inputs DI02 ... DI05 with the arguments n11/n21 / n12/n22 and activate FIXED SETP.
CHANGE (parameter 60_). You activate the fixed setpoints n13/n23 by assigning the functions n11/n21 and n12/n22 to two binary
inputs and applying a "1" signal to the two inputs.
