6 Design and Functions

The Z25 unit has 4 front-panel keys. The figure below shows the respective basic functions:
Function key
Menu navigation for parameter level
Incremental / Absolute switchover

The functions and key combinations of the keys are described in next section ( 6.3).
6.1

External Inputs

The device has 2 digital control inputs which can be connected via the 8 pin RIA connector S1.
The sensitivity of external input 1 is adjustable by parameter P19 and can be defined "level-sensitive" or "edge-
sensitive". The input is 24 VDC / PNP and active with a high level resp. with a positive edge.
The external input 2 is always „level-sensitive" and cannot be changed. The input is 24 VDC / PNP and active
with a high level.
The function of input 1 can be programmed by using parameter 17 (connector S1/5  9)

The function of input 2 can be programmed by using parameter 18 (connector S1/6  9)

(see parameter description  7).

Encoder Supply

An encoder supply of 24 VDC is available at Pin 1(-) and 2(+) of both connectors (8 pin RIA connector S1 and
female 9 pin D-SUB connector S2  9). The maximum current load is 300 mA.
Please note: there is no 5 VDC encoder supply available!
