8.2.2 Available PCP services
The PCP services (PCP = Peripherals Communication Protocol) serve to transmit
parameters via the PCP channel.
Lenze controllers support the following PCP services:
ƒ "Initiate": Establishing connection from the master to the controller (¶ 50)
ƒ "Abort": Aborting connection (¶ 50)
ƒ "Read": Reading parameters (¶ 51)
ƒ "Write": Writing parameters (¶ 51)
ƒ "Get−OD": Reading out the object directory (OD) (¶ 51)
ƒ "Identify": Identification of the controller (¶ 52)
ƒ "Status": Reading the status of the controller (¶ 53)
In the following, only those parameters and their contents are shown which are returned
by the Lenze controllers. All other transfer parameters of the given PCP services can be
obtained from the corresponding descriptions of the master.
