Starting up the inverter with INTERBUS (MCH42A)
Startup
Parameter channel
performs a read
service
To read a parameter via the parameter channel, it is necessary to execute a
PCP WRITE service first. The PCP WRITE service specifies where the data of the
inverter should be made available. A read service must be executed on the acyclic
parameter channel so that these data can reach the master. This means that the
execution of read services via the parameter channel always requires a PCP WRITE
and then a PCP READ service. The following table shows how read services are
executed via the acyclical MOVILINK
®
parameter channel.
1. Receipt is confirmed immediately; parameter channel is evaluated and requested
service is executed.
2. Service confirmation is entered into parameter channel and can be evaluated via
READ access in the master.
The MOVILINK
®
acyclic parameter channel is handled only locally on the INTERBUS
interface and is defined as shown in the following table.

1. Initiate the service coded in the parameter channel by means of a WRITE to the "MOVILINK
®
parameter
channel cyclical" object.

OK
2. READ "MOVILINK
®
cyclic parameter channel" and evaluation of service confirmation in the parameter
channel.
