40i TS - v1205 - Installation/Operation - (14/29)
3.4
General technical characteristics
Universal Power Supply between 100V AC and 240V AC ±10% at mains frequency between 45 Hz
and 400 Hz between 120V DC and 300 V DC. It withstands power outages of up to 20 milliseconds.
-10-year memory backup of installation parameters when the unit is off.
-The operating temperature inside the DRO enclosure must be between 5º C and 45º C (41ºF and
113ºF).
-The storage temperature inside the DRO enclosure must be -25º C and +70º C (-13º F and 158º F).
-Maximum relative humidity: 95% non condensing at 45ºC (113ºF).
-Front Panel Sealing: IP54 (DIN 40050), Rear panel: IP4X (DIN40050) except for built-in models in
which case is: IP20.

Connection of the feedback systems
The feedback systems (linear or rotary encoders) are connected via SUB-D HD type 15-pin female
connectors: X1 through X4.
Characteristics of feedback inputs: X1, X2, X3 and X4:
-Maximum feedback consumption: 250 mA at the +5V input.
-Admits square-wave signal (TTL).
-It admits voltage modulated 1 Vpp sinusoidal signal.
-It admits SSI communication for absolute encoders.
-Maximum frequency: 750 kHz
-Phase shift: 90º ±20º, hysteresis: 0.25 V, Vmax: 7V,
maximum input current: 3mA
- High threshold (logic state 1): 2.4 V < VIH< 5 V
- Low threshold (logic state 0): 0.0 V < VIL< 0.55 V
