Power Supply
The units require a DC supply from 17 to 30 V which must be applied to terminals 1 and 2.
Depending on the input voltage level and internal states, the power consumption may vary and
lies in a range of about 70 mA with a 24 V input (plus encoder currents taken from the auxiliary
voltage output).

Auxiliary Output for Encoder Supply
Terminals 4 and 3 provide a +5.2 VDC / 200 mA auxiliary output for supply of encoders and
sensors.
4.8.
Impulse Inputs for Encoders and Sensors
The setup menu of the unit allows individual setting of the desired characteristics of the signal
inputs. According to the application the units will accept single-channel signals (input A only with
no direction information) as well as dual channel signals A/B including information of the
direction of rotation. The following input formats and levels are acceptable:
symmetric differential input with RS422 format A, /A, B, /B
asymmetric (single-ended) TTL levels (A and/or B only without inverted channels)
HTL level 10 ... 30 V, alternatively differential (A, /A, B, /B) or single-ended
(A and B only, without inverted channels)
Signals from proximity switches or photocells providing HTL level (10 ... 30 V)
NAMUR (2-wire) signals
4.9.
Control Inputs
Two programmable control inputs allow the assignment of functions like remote start-up-delay,
reset of relay lock, hardware interlock of the keypad and similar.
Both inputs provide PNP characteristics and require HTL level. Also it is possible to set the control
function to "active LOW" or "active HIGH".
For evaluation of dynamic events the desired "active edge" can be set (rising or falling edge)
