•
The other will be used in speed control mode, where we require both acceleration and deceleration to
be active…
•
n019=2 sec n020=2 sec for speed control or any desired.
•
n54=11 (accel/deccel change by S5 or internally controlled by PLC) To allow the program to do the
changeover automatically. The PLC will simulate that input by 207.04 control bit
•
It is recommended a modified VF curve for better response in the lower frequency range … Typically
for Vector values like following are good initial values :
•
n015=30V, n016 = 0.1Hz , n017=15Hz
•
Keep n35=0 (0.01Hz resolution of speed references) for better resolution in speed control.
We also need particular settings in the PLC side :
In the PLC, following bits have to be cleared : IR209.00=0 and IR209.01=0. In this way we provide full Speed
reference and Run command control from the PLC regardless the inverter settings.
And the configuration for the input encoder (24Vdc type).
For the counter to work with the encoder we need following settings :
B-4-5
I/O Connections
In the template following basic inputs are predefined :
PLC Input 0
: A Channel encoder
PLC Input 1
: B Channel encoder
PLC Input 2
: Home/Origin sensor
Then the user program can use the rest of PLC and inverter inputs …
In our Application example we use :
PLC Input 3
for Home/Origin request and
