5.3.7 Increment Mode Relative (Mode 7)

Increment mode relative

Mode

Override 1 to 200%

Parameters

Forward/Reverse/Stop/Exec

Function

This mode differs from mode 6 primarily as regards specification of the target

position; in this mode, you specify the target coordinate in relation to the current

position of the drive.

As in mode 6, the incremental speed can be varied by specifying an Override

factor.

Prerequisites when a reference point has been set:

The resulting target coordinate must lie between the two software limit switches.

When you use this mode without having set a reference point, the target position

may lie anywhere within the range of the two hardware limit switches.

The positioning direction depends on

• the first function selected in this mode

and

• the sign of the position specification

Table 5-9 shows how the direction of travel is determined.
