Product overview
2.1 Properties
Introduction
The technology module enables you to connect up to four stepper motor axes to an S7-1500
system. The module is linked to technology objects by means of an implementation of the
PROFIdrive frame 3 and forms the interface to the drive. The number of steps that are output
is returned as the actual position value.
Properties

– Interfaces:
– Configurable diagnostics (per channel)
– Configurable interpulse period for auto reverse
– Configurable input delay: none, 0.05 ms ... 20 ms
● Supported signal types for pulse output
– Pulse encoder with direction signal
– Pulse encoder with forward signal and backward signal
– Incremental encoder with two signals with a 90° phase shift
● Supported system functions
– Isochronous mode
