Preselection 1 Menu
MODE 1
Switching conditions for preselection 1. Output switches under the following conditions:
0
|RESULT|>=|PRES|
Absolute value of the display value is greater or equal absolute value of
PRESELECTION 1
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value >= PRESELECTION 1  ON,
Display value < PRESELECTION 1 – HYSTERESIS 1 OFF
1
|RESULT|<=|PRES|
Absolute value of the display value is less or equal absolute value of
PRESELECTION 1 (start-up suppression (START UP DELAY) is advisable)
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value <= PRESELECTION 1  ON,
Display value > PRESELECTION 1 + HYSTERESIS 1 OFF
2
|RESULT|=|PRES|
Absolute value of the display value is equal absolute value of PRESELECTION
1
A range (Preselection +/- ½ Hysteresis) can be defined and monitored in
conjunction with the hysteresis.
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value > PRESELECTION 1 + ½ HYSTERESIS 1  OFF,
Display value < PRESELECTION 1 - ½ HYSTERESIS 1  OFF
3
RESULT>=PRES
Display value is greater or equal PRESELECTION 1, e.g. overspeed
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value >= PRESELECTION 1  ON,
Display value < PRESELECTION 1 – HYSTERESIS 1 OFF
4
RESULT<=PRES
Display value is less or equal PRESELECTION 1, e.g. underspeed
(start-up suppression (START UP DELAY) is advisable)
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value <= PRESELECTION 1  ON,
Display value > PRESELECTION 1 + HYSTERESIS 1 OFF
5
RESULT=PRES
Display value is equal PRESELECTION 1. A range (Preselection +/- ½
Hysteresis) can be defined and monitored in conjunction with the hysteresis.
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value > PRESELECTION 1 + ½ HYSTERESIS 1  OFF,
Display value < PRESELECTION 1 - ½ HYSTERESIS 1  OFF
6
RESULT=0
Display value is zero (Standstill after STANDSTILL TIME 1(s)),
e. g. standstill monitoring.
(Only in MODE: "START/STOP" + OPERATIONAL MODE: "SPEED" and in MODE:
"FREQUENCY").
7
RES>=PRES-TRAIL
Trailing PRESELECTION 1:
Display value is greater or equal PRESELECTION 1 – PRESELECTION 4  ON,
PRESELECTION 4 is the trailing value from PRESELECTION 1
8
ERROR SET
Error message for device errors.
