Transmitting individual parameters via AS-Interface
Communication with AS-Interface Double Slave GLK31A
The response of the MOVILINK
®
protocol is evaluated with the "Read request" service
as follows to make sure that the MOVIGEAR
®
inverter has changed parameter 8807.0 .
"Read request" service:
The slave replies after the system-related telegram runtime.
"Read response OK" response telegram:
Setting ramp t11
down Set ramp t11 down (parameter 8808.0 ) to 0.5 s. The ramp time for ramp t11 down is set
in the same way as the ramp time for ramp t11 up.
Ramp t11 down has index 8808
dec
= 0x2268 and subindex 0.
