10.1 Overview
10 System Connections
Tool class 1
 The user program confirms tool class 1. The PSENvip switches to a
RUN state.
 The PSENvip switches to a HOLD state if
– The tool class sent by the PSENvip and reflected by the user pro-
gram do not match.
– Errors occur in the communication protocol.
– Overall communication takes longer than 600 ms.
– A single communication phase takes longer than 200 ms (see
Chapter 4-4, section entitled "Communication sequence").
 Note:
The PSENvip switches to a RUN state if the user program fails to re-
act to the communication request via the PSENvip once a timeout of
200 ms has elapsed.
As a result, tools of tool class 1 can also be used with user programs
that do not support communication.
Tool class 2
 The user program confirms tool class 2. The PSENvip switches to a
RUN state.
 The PSENvip switches to a HOLD state if
– No communication is established (within 30 s on power-up, other-
wise within 200 ms).
– The tool class sent by the PSENvip and reflected by the user pro-
gram do not match.
– Errors occur in the communications protocol.
– Overall communication takes longer than 600 ms.
– A single communication phase takes longer than 200 ms (see
Chapter 4-4, section entitled "Communication sequence").
 The switchover point must be raised in comparison with the regular
switchover point. The switchover to lower speed must take place ear-
lier.
 The user program must convey a higher switchover point to the CNC
controller and then monitor this.
