3-81 Quick Stop Ramp Time
Range: Function:
Size [0.01 - Enter the quick-stop ramp-down time,
related 3600 s] which is the deceleration time from the
*
synchronous motor speed to 0 Hz. Ensure
that no resulting overvoltage occurs in the
inverter due to regenerative operation of
the motor required to achieve the given
ramp-down time. Ensure also that the
generated current required to achieve the
given ramp-down time does not exceed
the current limit (set in
parameter 4-18 Current Limit). Activate quick
stop with a signal on a selected digital
input, or via the serial communication port.

4.4.8 3-9* Digital Potentiometer
The digital potentiometer enables increase or decrease of
the actual reference by adjusting the set-up of the digital
inputs using the functions Increase, Decrease or Clear. To
activate the function, at least 1 digital input must be set to
Increase or Decrease.
3-90 Step Size
Range: Function:
0.10 % [0.01 - Enter the increment size required for
200 %] increase/decrease as a percentage of the
*
synchronous motor speed, n
decrease is activated, the resulting reference
is increased/decreased by the amount set in
this parameter.
3-92 Power Restore
Option: Function:
[0] Off Reset the digital potentiometer reference to 0% after
*
power-up.
[1] On Restore the most recent digital potentiometer
reference at power-up.
3-93 Maximum Limit
Range: Function:
100 % [-200 - Set the maximum permissible value for the
*
200 %] resulting reference. This is recommended if
the digital potentiometer is used for fine-
tuning of the resulting reference.
3-94 Minimum Limit
Range: Function:
-100 % [-200 - Set the minimum allowed value for the
200 %] resulting reference. This is recommended if
the digital potentiometer is used for fine-
tuning of the resulting reference.
3-95 Ramp Delay
Range: Function:
1000 [0 - Enter the delay required from activation
ms 3600000 ms] of the digital potentiometer function
*
until the frequency converter starts to
ramp the reference. With a delay of 0 ms,
the reference starts to ramp as soon as
increase/decrease is activated.
