INTRODUCTION
MB112EN - 11185046, 19A1, Baumer_HENQ1100_OI_EN 2/32
2. INTRODUCTION
The Baumer Hübner ENcoder Quality Measurement System HENQ 1100 is a hand-held
instrument for the testing of incremental encoders that produce HTL/TTL or SinCos signals.
Fast signal processing also facilitates the detection of sporadic errors, such as those caused
by interference in the signal leads or short voltage drop-outs in the power supply. The angu-
lar position and speed are in addition displayed continuously.
As well as Baumer Hübner incremental encoders, encoders from other manufacturers that
put out TTL/HTL or sin/cos signals can also be connected.
Power is fed to the encoder either via the HENQ 1100 or externally. So the encoder can be
run separately, disconnected from its normal supply, or one can tap into a system that is
running.
The operation of the instrument is carried out through the built-in user friendly keypad and a
4-line LCD with background lighting.
The memory makes it possible to collect measurements from several encoders and evaluate
them.
It is possible to connect a laptop or PC via the integrated RS-485 interface (optional RS-232
or USB-RS-485-converter).
Then a Windows measurement application enables a continuous display and recording of
current data, including any errors in the encoder or its wiring. Statistical evaluation is also
possible.
User-denedprolescanbeusedtoprogramvariousthresholdsasparameters,forinstan-
ce: permissible phase shift, permissible pulse/pause ratio.
Errors are signaled not only visually, through the LCD, but also acoustically, by a built-in
buzzer.

SETUP
5/32 MB112EN - 11185046, 19A1, Baumer_HENQ1100_OI_EN
5. SETUP
5.1 Connecting the encoder
Theincrementalencoderisconnectedtothe15-poleSUB-Dsocketthatistted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
INT/EXT ( INT : HENQ 1100, EXT : Controller).
5.4 HENQ 1100 with accumulator option
TheHENQ1100canoptionallybetted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.

SETUP
MB112EN - 11185046, 19A1, Baumer_HENQ1100_OI_EN 6/32
Inordertoincreasetheoperatingtime,aHENQ1100thatisttedwiththeaccumulatorop-
tion can be switched off by the On/Off switch.
If the HENQ 1100 is connected to the plug-in power supply, then the On/Off switch changes
it from charging mode (no display indication, display lighting is inactive) to measurement
mode and back again. On a HENQ 1100 without the accumulator option, the On/Off switch
has no function.
The accumulator is not charged up in measurement mode.
In accumulator operation, the encoder can still be supplied from the HENQ 1100, whereby
thecurrentconsumptionoftheencoderwilldecisivelyinuencetheoperatingtime.
5.5 Entering the encoder data (menu )
The HENQ 1100 makes provision for the attachment of any encoder with TTL (RS422),
HTL or SinCos output signals.
The encoder data are entered in menu as follows:
If the device is used in conjunction with encoders from Baumer Hübner, then the appro-
priate type (
1 - 40 ) can be selected in the menu item ENCODER , siehe Fig.5, page 16.
BecauseofthelargenumberofBaumerHübnerencodertypes,theeldforselectionis
restricted to the most common models available at present. When the encoder type has
been selected, the parameters MaxSpeed , inv.Sig. , ZeroPuls , with K2 , RefLevel
and Pulse-No are displayed for checking.
If your encoder is not present in the selection menu, select ‘
0 ’ (User Setting), see Fig.6,
page 16, in the menu item
ENCODER . Then you can set the encoder parameters th-
rough the menu items inv.Sig. , ZeroPuls , with K2 , RefLevel and Pulse-No , see
Fig.4, page 16 and Fig.6, page 16, individually by hand.
Itisalsopossibletoedittheencoderdatabasebyusingthe”cong“key,seeFig.7,
page 18. In the following submenu, the parameters encoder name
############# ,
MaxSpeed , inv.Sig. , ZeroPuls , with K2 , RefLevel and Pulse-No can be set
individually.
5.6 Measuring the encoder supply (menu )
After connecting up a incremental encoder, it is recommended to check the supply to the
encoder, see section 7.2.5, page 22.
For this purpose, the HENQ 1100 offers the option in menu of displaying the supply
voltages present at the encoder connection (5 V and 9...30 V), the current drawn (in mA)
and the power consumption (in mW).
This makes it easy to detect wiring errors, such as a short-circuit or cable break, or an
encoder fault.
The current drawn by the output driver that is integrated in the HENQ 1100 is shown in
the last line of the display. This will only be non-zero if the encoder signals provided by
the HENQ 1100 are passed on to a control system, see section 6.2.2, page 10.

SETUP
7/32 MB112EN - 11185046, 19A1, Baumer_HENQ1100_OI_EN
5.7 Checking the signal levels (menu )
The signal levels of the encoder can be checked in this menu.
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 necessary to check the levels.
At standstill, the momentary HIGH (H) and LOW (L) levels of the encoder signals will be
displayed.Ifthelevelisundenedorthereisnocorrespondingsignal(openinput),then
the ‘
? ’ symbol will appear.
When the encoder is rotating, correct signal levels will be acknowledged by a ‘ √ ’ mark.
5.8 Display measurements as text (menu )
In menu the following measurements are displayed as text, see also section 7.2.3,
page 20:
Display 1: Speed in revolutions per minute (
+00072 rpm )
For encoders that provide two signals in quadrature (K1 and K2, with a 90° phase shift),
the mathematical sign determines the direction of rotation. For encoders with a single K1
signal output, only the magnitude is shown.
Display 2: Pulse/pause ratio of the K1 signal (
K1=50:50 )
Therstgureindicatesthedurationofthehighlevelasapercentageoftheentirecycle.
ThesecondgureindicatesthedurationofthelowleveloftheK1signal,asapercenta-
ge.
Display 3: Pulse/pause ratio of the K2 signal (
K2=48:52 )
Therstgureindicatesthedurationofthehighlevelasapercentageoftheentirecycle.
Thesecondgureindicatesthedurationofthelowlevel,asapercentage.
)Please note:
Principle limitations mean that the pulse/pause ratio will be affected during rapid
acceleration.
Display 4: Angular position (
A=29.0° )
Display of the angular position, in degrees.
Display 5: Phase shift between K1 und K2 (
P=089° )
The displayed value is the phase shift (in degrees) between the rising edge of the K1
signal and the rising edge of the K2 signal.
)Please note:
If the pulse/pause ratio of the encoder signals K1 and/or K2 is other than 50:50,
then there will be different values measured for the phase shift between K1 and K2,
depending on the rotating direction.
Principle limitations also mean that the calculation of the phase shift will be affected
during rapid acceleration.

SETUP
MB112EN - 11185046, 19A1, Baumer_HENQ1100_OI_EN 8/32
Display 6: Position of the reference signal ( Z=282° )
This value gives the position (in degrees) of the reference signal relative to the position
of the encoder after the supply voltage for the HENQ 1100 is switched on or the encoder
changed.
5.9 Display measurements as graphics (menu )
A bar graph display is used for online presentation of the measured values.
The values indicated are, see also section 7.2.2, page 19:
Column 1:
The speed value ( shown at left, next to plain text with mathematical sign).
The scaling is made so that the highest bar corresponds to the value for the menu item
MaxSpeed set in menu .
Column 3 and 4:
This value gives the position and the position of the reference signal relative to the
position of the encoder after the supply voltage for the HENQ 1100 is switched on or the
encoder changed.
The lowest bar corresponds to 0° and the highest corresponds to 360°.
Column 6 and 7:
The pulse/pause ratio of the encoder signals K1 and/or K2, whereby the middle of the
bar corresponds to a 50:50 ratio. The highest or lowest value, respectively, refers to the
maximum error
MS_Error as set up in menu (for example 30:70 resp. 70:30).
Column 9:
The phase shift of K1 relative to the rising edge of K2, whereby the middle of the bar
corresponds to 90°.
In menu the maximum permitted phase shift can be set up in the menu item
PhaseErr .
The lowest bar corresponds to a [90° -
PhaseErr ] and the highest corresponds to a
[90° +
PhaseErr ].
Ifareferencesignalisavailable,itsrstappearanceisacknowledgedby
K0=OK! .
If the reference signal fails then even once, this will be detected and signaled by K0=ERR .
