SETUP
5.1 Connecting the encoder
The incremental encoder is connected to the 15-pole SUB-D socket that is fitted on the
left side of the HENQ 1100, see section 6.3.1, page 11 � Please note that, in the interest
of functional reliability, you should only wire up those pins in the encoder plug that are
actually required for the particular encoder (applies in particular to the pins for the supply
voltage 5 V oder 9���30 V)�
As an option, prefabricated cables with plug connectors are available for the various
types of encoder�
These cables have open cable ends on the encoder side�
5.2 Evaluation of sinewave signals
Evaluation of the signals from sinewave encoders can only be performed to a limited
extent, since the differential signals from the encoder are converted into TTL signals� It is
therefore not possible to check the levels�
The output from the HENQ 1100 is always a simulated TTL source, so that it is not pos-
sible to make a daisy-chain signal loop�
5.3 Connecting the supply voltage for the HENQ 1100
For proper operation, the HENQ 1100 requires a supply voltage of 9���30 V� The supply
must be able to carry a current load of at least 500 mA�
The connection is made through a 2-pole round socket on the right side of the instrument
with the inner conductor as positive pole, see section 6.1.2, page 9 �
The encoder power is supplied either from the the HENQ 1100, see section 6.2.1, page
10 , or from the frequency inverter or the control system, see section 6.2.2, page 10 �
The selection is made in menu

5.4 HENQ 1100 with accumulator option
The HENQ 1100 can optionally be fitted with an accumulator (12 V block accumulator with
integrated charging circuitry) that enables operation independently of the electrical supply
for up to 5 hours�
If, during this operation, the accumulator voltage falls below the permissible level of approx�
12 V, then the device will produce a “Low Battery Voltage” warning�
If the device is then not switched off, and the accumulator voltage continues to drop, then
the protection against complete discharge of the accumulator is activated, which will auto-
matically switch off the device�
It will then only be possible to switch on the device again when the accumulator has been
recharged� To fully recharge the accumulator, it is recommended that the HENQ 1100 is
attached to the plug-in power supply for about 5 hours� Charging will automatically be ended
as soon as the accumulator is fully recharged, and the voltage indicator (Menu ) will
show about 13 V�
