P108 Switch-off mode RF
Setting range
0 … 3
Other applicable parameter(s): P103, P107, P130, P210
Factory setting
{ 2 }
Description
This parameter determines the reaction of the motor starter on the removal of the
enable.
Note
As long as parameter P130=0 is set, switch-off mode is determined via the DIP switch
S2-DIP3/4. In this case the parameter can only be read, but not changed. It then
corresponds to the setting that is determined by the DIP switch. ( Section 4.2.2.4
"Overview of disconnection modes")
Setting values
Value Meaning
0 Switch-off mode 1
The phase control becomes continuous, increased from 0 to 100%
within the time period in accordance with P103 or potentiometer P3
(voltage drops). The brake is then applied in accordance with the
time specified by P107 or P3.
1
Switch-off mode 2
The phase control becomes continuous, increased from a start
value (Y) to 100% within a time period (X) (voltage drops). The
start value (Y) is determined by P210 or potentiometer P2. The
time period (X) is determined by P103 or potentiometer P3,
whereby the starting point of the time axis is shifted to the
theoretical start value (Y=0 %).
The brake is then applied in accordance with the time specified by
P107 or P3.
2
Switch-off mode 3
The output voltage is shut off immediately and the brake is applied
when the voltage reaches "0 %" or after P107 has elapsed.
3 Switch-off mode 4
The output voltage is shut off immediately and the brake is applied
in accordance with the time specified by P103 or P3.
P114 Brake release time FL
Setting range
0.00 ... 3.00 s
Factory setting
{ 0.05 }
Description
Setting of the time delay for enabling the motor after switch on.
Note
Electromagnetic brakes have a delayed reaction time for their release, which depends
on physical factors. If the brake release time set in parameter P114 is too long the
motor operates against the brake, which is still applied. This can result in a start-up
current that is too high, which will make the starter shut off with an overcurrent error.
P130 Parameter source FL
Setting range
0 … 1
Other applicable parameter(s) P550
Factory setting
{ 0 }
Description
Selection of whether the DIP switches (S1, S2) and potentiometers (P1-P3) have
priority over the parameter setting.
Note
• Switch-over of P130 from setting 1  0:
The RAM memory is deleted, parameter settings which have not been transferred
to the flash memory (P550) are lost.
• Switch-over of P130 from setting 0

1:
The default values of the parameter are used. To adopt parameter values from the
flash memory the FI must be restarted (note the wait time between two mains
switch on cycles! ( Section) 7 "Technical data").
Setting values
Value Meaning
0
Potentiometer/Switch
All parameters which are marked "RF" can only be read but cannot
be changed. These are determined by (S1, S2) and (P1-P3).
1 Flash memory
All settings at the device are determined by the parameters. (S1,
S2) and (P1-P3) have no influence.
2
Potentiometer switch + flash
As for setting "0" However, the functions of the digital inputs and
outputs are determined via the parameters (P420 or P434).
