Slave Modes for Multi-axis Cascaded Systems

Slave, Safe Limited Speed
Mode

When properly configured for Slave, Safe Limited Speed mode, the drive
performs the same functions as Safe Limited Speed mode as described on

page 71

.

However, the drive regards the Door Monitor input as a Door Control output
from an upstream axis, and performs a logical AND with its internal Door
Control signal to form the cascaded Door Control output. Door Monitoring,
Enabling Switch Monitoring, and Lock Monitoring functions are not allowed in
this mode.

For the door to unlock, all axes must be below safe limited speed.

Slave, Safe Limited Speed
Parameters

To configure the drive for Slave, Safe Limited Speed monitoring, set these
parameters in addition to the Slave, Safe Stop parameters listed on

page 91

. See

Multi-axis Connections

on

page 101

for details on configuring slave drives.

TIP

Only the middle and last drive in a multi-axis system can be configured for
slave modes.
