Digital in- and outputs
The next table indicates an overview of the functions, which can be assigned additionally to a digital input with
parameters di.24.. di.35 (only one auxilliary function is possible per input / bit 31 „I+ function“ must be activated
for the appropriate input):
di.24...di.35: Input- „+“ function
Value Explanation Fct. Para
1)
0: Reset master slave difference
Master position (ru.56) is overwritten with the slave po-
sition (ru.54)
PS.11
1: Set reference point
Actual position (ru.54) is overwritten with the reference
position (PS.17)
PS.13 *
2: Store position (teach)
actual position (ru.54) is transferred as target position
in PS.24
PS.36 *
3: Scan position
during state "active positioning" the actual position is
stored with positive edge at the input in ru.71 „Teach/
scan position display“.
PS.37 *
4: Relative position F/R
Rotation setting for relative positioning (only if in PS.27
for position setting the mode „relative to PS.38“ is se-
lected
PS.38
5: Software ST (not at di.35)
any digital input gets the function "control release" (soft-
ware emulation / function can not be set to input ST)
di.36
6: ST locking (not at di.35)
Setting the input effects a locking of the software con-
trol release
di.37
7: Reference point correction
Connection of the switches for ying referencing at slip-
aficted systems
PS.43
8: Brake monitoring
Between the end of the brake closing period (Pn.40)
and the beginning of the break opening period (Pn.36)
the brake must always be closed. If the input becomes
(or is) active during this phase, E.br is triggered.
Pn.42
9: Dead time compensation off
As long as the input is active, the dead time compensa-
tion is switched off
uF.21
10: USV operation 400V class
Activation of the input causes reduction of the level for
triggering and resetting of the undervoltage error
Pn.78
11: no digital ST (di.35 no function)
Control release only preset via terminal block (di.01 /
di.02 and control word SY.43 / SY.50 without function)
di.39
12: Start autom. Rs temperature
correction
Start of the temperature-dependent stator resistance
adaptation (only at V/f characteristic open-loop opera-
tion and SMM)
dr.61
13: Encoder channel 2 / transfer
value
The value of Ec.61 - Ec.32 before (at 14: and Ec.60
- Ec.31 before) is scanned with the positive edge and
stored in Ec.50 / Ec.51
EC.48
14: Encoder channel 1 + 2 / trans-
fer value
EC.49
15: reserved
16: Register fct. Master input
17: Register fct. Slave input
18: Target position
Determines the input for selection of positions. Evalua-
tion depending on PS.56.
PS.57
