P426

Quick stop time

S P

Always available

0 ... 10.00 s
[ 0.1 ]

Deceleration time setting for the quick stop function, which can be triggered by digital input, bus
control, keyboard or automatically in the case of an error.
Quick stop time is the time for the linear frequency decrease from the set maximum frequency (P105)
to 0Hz. If an actual setpoint <100% is being used, the emergency stop time is reduced
correspondingly.

P427

Quick stop on error

0 = Off, automatic quick stop during error is deactivated
1 = With mains failure, automatic quick stop during mains failure
2 = With

errors

, automatic quick stop during error

3 = Error or mains failure, automatic quick stop during mains failure or error

P428

0 = Off, the FI needs a flank for enable (signal change from "low" to "high") at the respective

digital input or PotentiometerBox switch.

1 = On, the FI reacts to a high level. This applies both for digital input signals and switched

PotentiometerBox.

2 = Immediate

with

mains

voltage

, when the mains voltage is switched on, the drive starts

immediately with the set minimum or jog frequency without a high level being present at a
digital input or via the PotentiometerBox.
Requirement: No digital inputs should be programmed for enable!


Setpoint specification:
Without analog input signal via customer unit or PotentiometerBox:
Æ

Set minimum frequency (P104) or jog frequency (P113)

P104 = Only positive value can be set for rotation right

P113 = Right or left rotation depending on sign

Æ

If P104 and P113 are set with same sign, they are added.

With analog input signal via customer unit or PotentiometerBox:
Æ

P104 applies as minimum value for analog input signal (CU or potentiometer),

is therefore not added. P105 (max. frequency) is the maximum value for

the analog input signal.

Æ

When the jog frequency is set (P113), it is added to the analog input signal.

Æ

When the PotentiometerBox is used, the switch is inactive (only operating light).

Attention

If no digital input is programmed for "Enable" and the parameter P428 is changed
to [2]= "Immediate with mains", the motor will start immediately because all enable
conditions have been fulfilled.
