10-3

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.
