Description of power section parameters
Parameters
Binary inputs
DI10 – DI17
index 8348.0,
bits 0 – 7
The parameters show the status of the virtual binary inputs DI10 to DI17.
Binary inputs
DI10 – DI17
index 8340.0 –
8347.0
This parameter is used to specify the assignment of virtual binary inputs DI10 – DI17, or
the assignment of the binary inputs of an application option. You can program the binary
inputs to the following functions:
Power section parameters \ terminal assignment \ binary outputs
Binary outputs
DO10 – DO17
index 8360.0,
bits0–7
The parameters show the status of the virtual binary outputs DO10 to DO17.
Binary outputs
DO10–DO17
index 8352.0 –
8359.0
This parameter is used to specify the assignment of virtual binary outputs DO10 – DO17,
or the assignment of the binary outputs of an application option. You can program the
binary outputs to the following functions:
Function
Effect in case of
"0" signal "1" signal
0 = No function ––
1 = Enable/Stop Stop at t13 Enable
2 = CW/stop Stop at t11 or t12 Enable CW
3 = CCW/stop Stop at t11 or t12 Enable CCW
4 = n11
n13
External setpoints only n11
n13
5 = n12 External setpoints only n12
8 = Speed ramp 2 1st ramp (t11) active 2nd ramp (t12) active
9 = Reserved ––
10 = Reserved ––
11 = /External error, 0 active External error –
12 = Error reset Reset on positive edge ("0" to "1")
13 = Reserved ––
14 = /Limit switch right Right limit switch reached Not reached
15 = /Limit switch left Left limit switch reached Not reached
16 = IPOS input Function depends on IPOS function
17 = Reference cam Not activated Activated
18 = Reference travel start – Start referencing for IPOS
19 = Slave free running Master-slave operation Slave free running
20 = Setpoint acceptance active Do not accept Accept setpoint
30 = /Controller inhibit, 0 active Controller inhibit active Controller enabled
INFORMATION
The binary signals are only valid if the inverter has signaled "ready" after it has been
switched on and if no error message has been issued. Binary signals have "0" status
while the unit is being initialized.
Several terminals can be assigned the same function.
